Clearwire recently announced eight Texas communities will receive Mobile WiMAX service by September, in addition to Boise, Idaho and Bellingham, Washington.

But three Texas towns — Abeline (pop: 115,930), Lubbock (pop: 212,169), and Wichita Falls (pop: 107,000), already have Mobile WiMAX service. They get theirs from Xanadoo, reports Information Week.

Xanadoo has offered WiMax service in Texas for over two years. Xanadoo also offers WiMax in communities in Oklahoma and Illinois.

“We are not working with Xanadoo,” said a Clearwire spokesman. “We offer service to more cities than they do in Texas but in the three markets where we overlap, we would be competing.”

Xanadoo uses infrastructure provided by Navini Networks, a Texas company that was acquired by Cisco in late 2007. Cisco also works with Clearwire, which already has WiMax service in the major urban areas of Atlanta, Baltimore, Las Vegas, and Portland, Oregon. Cisco’s beamforming basestations are said to improve range and reduce interference.

Xanadoo is also a licensee of 700 MHz spectrum covering almost 156 million people in major markets, such as New York, Boston, Philadelphia, Pittsburgh, Cleveland, Detroit, Chicago, Miami, Tampa, San Francisco, Portland and Seattle. Xanadoo expects that 4G will be deployed in the 700 MHz frequency band.

Philadelphia’s WiFi Network may also be a target for Clear. The Network Acquisition Company, largely funded by Tropos founder Dave Hanna, bought the WiFi system from Earthlink. Wireless Philadelphia (now called The Digital Impact Group), is the nonprofit organization with the primary mission of bridging the City’s vast digital divide.
