  15. LTE Standards status January 2008 LTE Terrestrial Radio Access Network technology specifications have been approved by 3GPP and are now under change control, leading to their inclusion in the forthcoming 3GPP Release 8. • Hardware impacting L1/L2 specifications functionally frozen for both FDD and TDD. Full set of 3GPP Release 8 system specifications on track for approval during Q4 2008.

  16.

  17. LTE Mobility Advantages AT&T will continue to utilize WiMAX for applications primarily focused on fixed LTE Advantages for Mobility: • Most customers, devices and applications • Supports worldwide roaming • Compatibility with existing AT&T Networks • Designed to support efficient voice operation (VoIP)

  18. LTE Mobility Advantages • Shorter frame size, lower amounts of overhead, and lower overall latency than WiMAX • LTE data throughput will be equivalent to or betterthan WiMAX when both are operated in FDD mode • LTE shorter frame size supports higher throughputs at moderate to high vehicle speeds
