AT&T turned on 700 MHz interoperability feature in network, is selling Band 12-capable devices
October 5, 2015
AT&T Mobility (NYSE: T) said it continues to work with several smaller carriers, likely including T-Mobile US (NYSE:TMUS) and U.S. Cellular (NYSE:USM), to create roaming between different 700 MHz band classes but is still encountering some hurdles. Nevertheless, in delivering a progress report on its 700 MHz interoperability efforts to the FCC, AT&T noted that it has turned on the feature in its network that lets its network operate simultaneously in both Band 12 and Band 17 and support devices in both band classes.
AT&T had pushed for the creation of its own Band Class 17 and previously argued it could not support Band Class 17 alongside Band Class 12 because it would be too expensive and would cause interference. However, in September 2013, AT&T agreed to reverse its position and support both Band Class 17 alongside Band Class 12. Specifically, the company said it will develop, implement and deploy throughout its network multi-frequency band indicator (MFBI) capabilities to support the interoperability.
