AT&T has announced plans for a major expansion of its 3G wireless broadband coverage in 2008. The plans include expanding service to more than 80 unspecified new cities, as well as an enhancement in upload speeds provided by an upgrade to High Speed Uplink Packet Access (HSUPA) technology. The planned expansion is expected to deliver 3G services to nearly 350 leading U.S. markets by the end of 2008, including all of the top 100 U.S. cities. A list of cities currently supporting 3G can be found here; the 3G initiative will include the roll out of more than 1,500 additional cell sites nationwide. “Fast wireless broadband is the foundation for a whole range of new and emerging applications that our customers are adopting, including everything from social networking to sending live video and large business files,” said Ralph de la Vega, president and CEO for AT&T’s wireless unit. “With these aggressive initiatives, we’re expanding the scope and the speed of our 3G capabilities, connecting people with their world and enabling more customers to do more with their wireless devices, wherever they may be.” Although not directly mentioned in the announcement, AT&T CEO Randall Stephenson has previously said that a 3G-capable iPhone model will be released this year.
