Limitations not induced by the Technology itself but time frames required to upgrade infrastructure and transport networks, obtain devices with corresponding capabilities and IOT tests


Lte mobility advantages

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)


Lte mobility advantages1

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
