Broadband Access is KeyBut availability is an issue 70% of the worlds populationlives beyond the reach of a wired broadband network today
Only 4.6% of the people on Earth have broadband access
Even in the top 20 most connected countries the averagebroadband penetration is only 23% of the population
Nearly 6 billion people in Africa, the Middle East, Asia,Europe, and the Americas are not yet connected...

Why Arent More Connected?Simple Economics
Service providers must find a way to be
profitable even in markets where:Population densities are low or communities
widely dispersed
Geographic conditions make deployment of
wired networks difficult, slow, and expensiveProsperity levels limit the addressable market,service-mix and revenue potential
Skill-sets needed to deliver all aspects of a
service are underdeveloped or missing
New network architectures are
needed

Mobile WiMax Vocabulary
1. Frequency Range
Which part of spectrum has been assigned to WiMax operator by the regulator
WiMax Forum will primarily certify for 2.5-2.7 GHz and 3.4-3.6 GHz2. Channel Bandwidth
Spectrum bandwidth used for a single sector in a single cell site
Measured in Megaherz, determines the overall capacity within a sector
WiMax Forum will certify for 5 and 10 MHz channel bandwidth.
3. Duplex Mode
Frequency division duplex (FDD) two separate channels are used for transmitand receive
Time division duplex (TDD) transmit and receive in the same channel,separated by time
WiMax Forum will certify for TDD only.
4. Guard Band
Part of unused spectrum at the edge of providers frequency range. Givesenough reserve to protect against interference.

Benefits Uplink, Downlink. Improves desired signal, reduces interference.
H-ARQ is also included in the Mobile WiMAX standard as an intelligent retransmissionScheme
Applied by most vendors to improve link budget but does not improve SINR
Increasing transmission scheme will impact delay and bandwidth

Policy server and ASN-GW/PCEP track time-usage (which can be viewed by user at portal)5. PCEP detects that session has expired and asks policy server for action
