Cox Communications has announced the successful completion of voice calling and high definition (HD) video streaming over wireless networks using fourth generation (4G) Long Term Evolution (LTE) technology.

Cox’s 4G technology and service trials utilize the AWS and 700 MHz spectrum that it acquired at Federal Communication Commission auctions in 2006 and 2008. Cox spent over $550 million for radio spectrum licenses to support its wireless plans, which include wireless broadband.

Cox conducted the 4G trials in Phoenix and San Diego and chose these markets for the advanced technology-orientation of its residential and business customers, as well as the terrain and suburban density variances of their geographies.

While Cox is testing 4G LTE technology in these markets, it is initially deploying wireless services using the 3G CDMA standard in Hampton Roads, VA; Orange County, CA; and Omaha, NE. (For more, click here).

"On the heels of announcing our initial 3G wireless service deployments, today’s news demonstrates our equal commitment to 4G services," said Stephen Bye, Cox’s VP of wireless, in a statement.

Collaborating with Cox in conducting the 4G trials and testing the wireless services and applications were Alcatel-Lucent and Huawei.
