US-based cableco Cox Communications has announced the successful completion of trials of voice calling and high definition video streaming over wireless networks using Long Term Evolution (LTE) technology. The trials, which were conducted in Phoenix and San Diego, use the AWS and 700MHz spectrum that Cox acquired at Federal Communications Commission (FCC) auctions in 2006 and 2008. The company is also using its spectrum holdings to trial 3G services. As reported by CommsUpdate on 10 December 2009, Cox launched 3G trials in three cities: Hampton Roads, Virginia; Omaha, Nebraska; and Orange County, California. Stephen Bye, Cox’s vice president of wireless, said: ‘On the heels of announcing our initial 3G wireless service deployments, today’s news demonstrates our equal commitment to 4G services. Through the LTE trials, we are utilising the AWS and 700MHz spectrum to test voice, data and video applications and services and ultimately readying to deploy 4G wireless broadband services to meet the needs of our customers. 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.’ The trials have been conducted in partnership with Alcatel-Lucent & Huawei Technologies.
