The upgrade to High Speed Packet Access (HSPA) 7.2 technology is part of AT&T’s plan for continued investments. With its network built on the 3G UMTS technology that is commonly deployed throughout the world, AT&T can boost the speed of its mobile broadband network and offer a wide variety of devices to take advantage of it well in advance of 2011-2012, when most industry observers expect 4G LTE networks and device availability to scale, according to Ralph de la Vega, president and CEO, AT&T Mobility and Consumer Markets.. AT&T plans to begin LTE trials in 2010, with deployment beginning in 2011.

In addition to the planned speed upgrade, AT&T is enhancing its mobile broadband coverage by nearly doubling the wireless spectrum dedicated to 3G in most metropolitan areas to deliver stronger in-building reception and more overall network capacity. Also, AT&T is adding thousands of new cell site backhaul connections to support the higher mobile broadband speeds enabled by HSPA 7.2 and LTE.
The upgraded network platform could allow for theoretical peak speeds of 7.2Mbps. Typical real-world downlink and uplink speeds experienced by customers with upgraded 3G will be less than the theoretical peak and will vary based on a number of factors, including location, device, and overall traffic on the local network at a given time.

AT&T’s 3G mobile broadband network is now available in nearly 350 U.S. major metropolitan areas, with about 20 additional metro areas planned for deployment in 2009. The HSPA 7.2 technology will be deployed widely in the network, with the benefits of the network upgrade to be announced on a local basis as the faster speeds are turned up. AT&T will introduce multiple HSPA 7.2-compatible laptop cards and smartphones beginning later this year.
