15 April 14, 2015 Page 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 Q

17 April 14, 2015 Page 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 April 14, 2015 Page 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 better than WiMAX when both are operated in FDD mode LTE shorter frame size supports higher throughputs at moderate to high vehicle speeds
