Clearwire (NASDAQ:CLWR) is getting a bit cozier with the world's largest mobile operator. The U.S. WiMAX operator has had a TD-LTE partnership in place with China Mobile since September, and the companies announced this week that they also have agreed to interoperability testing for upcoming TD-LTE devices.
The companies will set up testing and interoperability labs along with other carriers who are part of the Global TD-LTE Initiative and test devices operating at frequencies from 2.3GHz to 2.7GHz. Clearwire's labs will be in Phoenix, Ariz., and Herndon, Va., and will open up for interoperability testing later this year.
The news of progress on the multi-mode multi-band TD-LTE and LTE FDD front is the latest note in a bit of a revival for Clearwire, whose importance in the wireless industry recently has been underlined by the company's strong spectrum position.
