Mobile networks as a medium for data transmission and telecontrol
in the energy industry

Starting situation
Often no infrastructure available for the distribution networks in the field (e. g. fibre optical cable).
=> Radio-based solutions cover the gaps!
Energy suppliers and industry often have their own intra-company digital radio infrastructure. => Added value through simultaneous use for
data transmission.
Public mobile communication networks provide comprehensive area coverage and are increasingly used for data transmission.

Which technologies are available?
Public networks:
2G- standard, comprehensive area-coverageGSM, GPRSGSM, GPRS
3G- standard, network often not set up in rural regions
4G- Standard, network roll-out in rural regions has priority now!

Comparison between strategies: public or company-owned infrastructure?
Public networks:
No investment in network infrastructure
High data rates
Security and availability sometimes critical (organisational fault)
Tariffs to be paid
Company owned infrastructure:
If not set up yet, high expenditure on network infrastructure
Lower data rates compared against public networks, but: What demand is really necessary economically ?
Security and availability are always in the company‘s hands.
Value-added through simultaneous use for mobile radio as well as data transmission

Latest generation mobile communication technology as a medium for providing broadband coverage in rural regions
„Long-Term-Evolution“
08.10.2010 © by Kellner Telecom, 2010 11
Mobile communication technology is dramatically gaining in importance for data transmission
Number Mobile broadband users are expected to nearly double between 2009 (22 mn) and 2011 (43 mn) in Europe. (forecast by CCS insight)
The volume of internet data transmitted mobile is experiencing an explosive growth.

LTE – Facts about the technology (1)
Socalled „4th generation standard“
Further development of current mobile standards UMTS/HSPA/HSPA+, etc.
3GPP standard Frequencies: 0,8GHz, 1,8GHz, 2,0GHz, 2,6GHZ Network completely IP-based
Transmission rates: downlink 100 - 368 Mbit/s
uplink: 50 Mbit/s
Access mode: downlink OFDMA
uplink: SC-FDMA
08.10.2010 © by Kellner Telecom, 2010 14
LTE – Facts about the technology (2)
extremely short latencies < 10 ms
enhancing of capacity by multiple antenna technology (mimo, multiple input, multiple output)
first commercial LTE-networks have been perating in Oslo and Stockholm since 14th December 2009
first promising field trials have been completed in Germany
LTE is being rolled out in addition to GSM, UMTS, HSPA, etc.
applications: internet (mobile, fixed), mobile TV, M2M communication, etc.

Auction in LTE frequencies
The Federal Network Agency sold the following
frequencies in a limited auction from 12th April to 20th May 2010:
Frequency bands:0,8 GHz (socalled „digital dividends“, unused analogue TV frequencies)
1,8 GHz, 2,0 GHz, 2,6 GHz
Participants: - Vodafone - T-Mobile - eplus - Telefonica/O2
08.10.2010 © by Kellner Telecom, 2010 17
Constraints and obligations for network roll out:
1,8 GHz, 2,0 GHz, 2,6 GHz: at minimum 25% of the population by 1st January 2014 at minimum 50% of the population by 1st January 2016
0,8 GHz:
at minimum 90% of the population living in the cities and communities specified by the Federal Länder (socalled “white spots”) shall be covered by 2016
1st priority : < 5000 inhabitants
2nd priority: < 20000 inhabitants
3rd priority : < 50000 inhabitants
4th priority: > 50000 inhabitants
08.10.2010 © by Kellner Telecom, 2010 18
Strategy of the operators for network roll out:
Installation of up to 7000 new sites per year and operator, Roll out has already started.
Almost exclusive use of existing mobile communication sites, i.e. upgrading of existing sites (system technology, antenna system, etc.)
Capacity of the access network must be enhanced to an important degree. (microwave links, FOC)
