Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos
Introduction to Mobile and Networks 3
technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos
Introduction to Mobile and Networks 3
technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos
Introduction to Mobile and Networks 3
technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos
Introduction to Mobile and Networks 3
technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

ndash has a scalable bandwidth between 125 and 20 MHz (OFDMOFDMA systems are well suited for wide and scalable bandwidths)
ndash supports flat mixed and distributed network architectures

Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations

11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

viable technology in 2004 LTE offers a number of distinct advantages over other wireless technologies including increased performance attributes such as
ndash high spectral efficiency
ndash very low latency
ndash it supports variable bandwidths
ndash simple protocol architecture
ndash compatibility and interworking with earlier 3GPP releases
ndash interworking with other systems eg cdma2000
ndash Frequency division duplex (FDD) and time division duplex (TDD) within a single radio access technology
ndash efficient multicastbroadcast

Preface
The world of mobile and wireless networks is only 10 years old but is still expanding and evolving Instead of settling in to a steady state the changes are accelerating The upcoming 3 to 5 years will expand on the current developments under 5G This book aims to present the state-of-the-art in the field of mobile and wireless networks and to anticipate the arrival of new standards and architectures
After a description of the existing standards mainly 2G 3G and LTE this book addresses LTE-A which is the first 4G release and provides a first indication of 5G as seen through the normalizing bodies
4G technology is described in detail with the different LTE extensions related to the arrival of femtocells the increase to 1 Gbps capacity and relay techniques 5G is also discussed to show what can be expected in the near future and more precisely A chapter is devoted to ldquosmall cellsrdquo that allow offloading techniques for discharging large antennas and enable heterogeneous networks through integration with the normal macrocell
Subsequently the book focuses on wireless networks starting with small personal area networks and progressing to very large
xiv Mobile and Wireless Networks
wireless regional area networks via local area networks dominated by WiFi technology and finally metropolitan networks Current personal area networks are described through Bluetooth and new types of wireless networks such as WiGig The WiFi family continues to expand and all new members are described
The Internet of Things is explained in a specific chapter due to its omnipresence in the literature The forecast anticipates 100 billion connected devices by 2020 But standardized architectures and protocols are limited which makes this field a very dense area with numerous proprietary networks This book provides a simplified vision that ultimately makes the Internet of Things easy to understand
Ad hoc and mesh networks are important as they have made a comeback after a long period of near hibernation New and significant progress has been made in the field of algorithms that allows such networks to run smoothly while providing high quality service
The last chapter discusses mobile edge computing (MEC) servers These servers placed close to users at the edge of the network provide a cloud signifying decentralization towards data centers which are much smaller than the leading cloud providers These servers should be used to support all the associated algorithms for accessing networks user data management virtual machine storage and secure communication access MEC is becoming more and more important with the massive scale of Internet traffic Concentration of data and computing in a global cloud is becoming impractical the world of connectivity is moving towards distributed data centers and MEC servers
This book describes the development of wireless and mobile networks and how they will evolve in the future The book is not exhaustive because the field is vast and still expanding

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos
Introduction to Mobile and Networks 3
technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

ndash has a scalable bandwidth between 125 and 20 MHz (OFDMOFDMA systems are well suited for wide and scalable bandwidths)
ndash supports flat mixed and distributed network architectures

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

them in order to see the effect of such technology not only on the market drivers but also on research domain areas
11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking
111 First generation mobile technology 1G
First-generation cellular networks (1G) were analog-based and limited to voice services and capabilities Compared to todayrsquos
Introduction to Mobile and Networks 3
technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

ndash data rates of over 275 Mbps in the downlink (base station to mobile) and over 75 Mbps in the uplink (mobile to base station)
ndash uses an OFDM OFDMA air interface
ndash uses FDD
ndash possesses an IP network architecture
ndash has a scalable bandwidth between 125 and 20 MHz (OFDMOFDMA systems are well suited for wide and scalable bandwidths)
ndash supports flat mixed and distributed network architectures

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations

11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
Introduction to Mobile and Networks 5
As the successor of CDMA2000 CDMA2000 1xEV-DO Release 0 provides peak speeds of up to 24 Mbps with an average user throughput of between 400 and 700 Kbps The average uplink data rate is between 60 and 80 Kbps Rel 0 makes use of existing Internet protocols enabling it to support IP-based connectivity and software applications In addition Release 0 allows users to expand their mobile experience by enjoying broadband Internet access music and video downloads gaming and television broadcasts
1xEV-DO Release 0 has been revised to produce Revision A (Rev-A) which increases peak rates on reverse and forward links to support a wide-variety of symmetric delay-sensitive real-time and concurrent voice and broadband data applications It also incorporates orthogonal frequency-division multiple access (OFDMA) technology to enable multicasting (one-to-many) for multimedia content delivery As the successor of Rev-A 1xEV-DO Revision B (Rev-B) introduces dynamic bandwidth allocation to provide higher performance by aggregating multiple 125 MHz Rev-A channels
114 Fourth generation mobile technology 4G
Fourth-generation or 4G technologies allow wireless carriers to take advantage of greater download and upload speeds to increase the amount and types of content made available through mobile devices 4G networks are using full IP solutions that deliver voice data and multimedia content to mobile users anytime and almost anywhere They offer greatly improved data rates over previous generations of wireless technology Faster wireless broadband connections enable wireless carriers to support higher-level data services including business applications streamed audio and video video messaging video telephony mobile TV and gaming
As a step toward 4G mobile broadband wireless 3GPP began its initial investigation of the Long-Term Evolution (LTE) standard as a

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

11 Mobile and wireless generation networks
The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

modulation and coding within the existing carrier bandwidth of 200 kHz
113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps

Introduction to Mobile and Networks
The development of mobile and wireless communications was traditionally viewed as a sequence of successive generations The first generation of analog mobile telephony was followed by the second or digital generation The third generation enables full multimedia data transmission as well as voice communications The fourth generation is completely Internet Protocol (IP)-based including voice communications and increases the throughput in parallel to these activities related to the evolution of current fourth-generation (4G) wireless technologies There is also increased research effort on future radio access referred to as fifth-generation (5G) radio access Such future radio access is anticipated to take the performance and service provisioning of wireless systems a step further providing data rates of up to 200 Mbps with wide-area coverage and up to 1 Gbps with local-area coverage 5G technologies are being focused on as it is expected to eventually deliver approximately 10 Gbps This can be considered as a normal evolution in response to increased user behavior demand and quality of service (QoS) expectations
In this chapter we provide a brief overview of mobile and wireless networks (MWN) The objective is to present the background and context necessary for understanding subsequent chapters We review the history of MWN enumerate their applications and compare

The International Telecommunication Union (ITU) launched International Mobile Telecommunications (IMT-2000) as an initiative to cover high-speed broadband and IP-based mobile systems featuring network-to-network interconnection featureservice transparency global roaming and seamless services independent of location IMT-2000 aims to bring high-quality mobile multimedia telecommunications to a worldwide mass market by increasing the speed and ease of wireless communications responding to problems due to increased demand to pass data via telecommunications and providing ldquoanytime anywhererdquo services
Two partnership organizations were born out from the ITUndashIMT-2000 initiative the Third Generation Partnership Project (www3gpporg) and the Third Generation Partnership Project 2 (www3gpp2org) The 3GPP and 3GPP2 developed their own version of 2G 3G and later mobile systems In parallel the Institute of Electrical and Electronics Engineers (IEEE) was developing proper versions of the wireless networks that can be compared functionally with those of 3GPP and 3GPPP2 and their technology-based generations can be crossed with those of 3GPP and 3GPP2 Their terminologies are different but the goal is the same which is to develop new technologies that make use of advances in the area of wireless and mobile technologies This is why we will summarize all the generations developed by these organizations as a path of evolution in the world of mobile and wireless networking

technology 1G technology was vastly inferior In the late 1970s and early 1980s various 1G cellular mobile communication systems were introduced the first such system the Advanced Mobile Phone System (AMPS) was introduced in the United States in the late 1970s Other 1G systems include the Nordic Mobile Telephone System (NMTs) and the Total Access Communications System (TACS) While these systems offer reasonably good voice quality they provide limited spectral efficiency The evolution toward 2G was thus necessary to overcome the drawback of such technology
112 Second generation mobile technology 2G
The second-generation (2G) digital systems promised higher capacity and better voice quality than their analog counterparts The two widely deployed 2G cellular systems are Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) that was originally known as American Interim Standard 95 or IS-95 and is now called cdmaOne Both the GSM and CDMA camps formed separate 3G partnership projects (3GPP and 3GPP2 respectively) to develop IMT-2000-compliant standards based on the CDMA technology GSM differs from 1G by using digital cellular technology Time Division Multiple Access (TDMA) transmission methods and slow-frequency hopping for voice communication In the United States 2G cellular standardization process utilized direct-sequence CDMA with phase-shift keyed modulation and coding
There was an evolution of main air interface-related enhancements to GSM (1) higher data-rates for circuit-switched services through aggregation of several time-slots per TDMA frame with high-speed circuit-switched data (HSCSD) (2) general packet radio service (GPRS) which had efficient non-real-time packet-data traffic support GPRS reached peak data rates of up to 140 Kbps when a user aggregated all timeslots and (3) enhanced data rates for global evolution (EDGE) increased data rates up to 384 Kbps with high-level

113 Third generation mobile technology 3G
Further evolution of the GSM-based systems is handled under 3GPP to define a global 3G Universal Mobile Telecommunications System (UMTS) The main component of this system is the UMTS Terrestrial Radio Access Network (UTRAN) based on Wideband Code Division Multiple Access (WCDMA) radio technology since it uses 5 MHz bandwidth and GSMEDGE Radio Access Network (GERAN) based on (GSM) enhanced data rates
3GPP2 implemented CDMA2000 in the 125 MHz bandwidth which increased voice and data services and supported a multitude of enhanced broadband data applications such as broadband Internet access and multimedia downloads This technology also doubled user capacity over cdmaOne and with the advent of 1xRTT packet data was available for the first time
The 3GPP2 first introduced high-rate packet data (HRPD) termed CDMA20001xEV-DO This standard enables high-speed packet-switched techniques designed for high-speed data transmissions enabling peak data rates beyond 2 Mbps 1xEV-DO expanded the types of services and applications available to end users enabling carriers to broadcast more media-rich content
The 3GPP enhanced the WCDMA system providing high-speed downlink packet access (HSDPA) that brought spectral efficiency for higher speed data services in 2001 Then High-Speed Uplink Packet Access (HSUPA) was introduced in 2005 The combination of HSDPA and HSUPA is called HSPA The latest HSPA is HSPA+ which resulted from adding multiple inputmultiple output (MIMO) antenna capability and 16QAM (Uplink)64QAM (Downlink) modulation Coupled with improvements in the radio access network for continuous packet connectivity HSPA+ allows uplink speeds of 11 Mbps and downlink speeds of 42 Mbps
