Cox announced the successful completion of voice calling and high definition video streaming over wireless networks using 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. The company informed that they 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 some regions of California and Nebraska.

“We are encouraged by the success of the Phoenix and San Diego tests, which further validate our decision to pursue 4G based on LTE, specifically the 3GPP Release 8 standard," said Stephen Bye, Cox’s vice president of wireless.

Next month, Bye will expand on Cox’s 4G learnings as he participates in a keynote session titled "Ready for Launch of Next Generation Mobile Networks" at Mobile World Congress in Barcelona.

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

Cox, the third-largest U.S. cable TV company, provides digital video, internet, telephone and wireless services over its own nationwide IP network.
