AT&T trials mobile WiMAX

The largest wireline telco in the US, AT&T Inc, has revealed that it has been operating a mobile WiMAX trial in Nevada for several months. Telephony Online reports that the firm is using pre-certification mobile WiMAX technology from Soma Networks for its pilot trials in the Nevada town of Pahrump, which is home to around 45,000 people. AT&T is currently using the network as a fixed wireless broadband system, providing an alternative to wired high speed technologies such as cable and DSL. However, the equipment which has been deployed is based on the mobile WiMAX 802.16e specification. AT&T has limited WiMAX-ready spectrum in the 2.3GHz Wireless Communications Services band.
