AT&T to double speeds on wireless networks

AT&T plans to upgrade its 3G wireless network with the hopes of doubling speed by completion in 2011. The upgrades start later this year.

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 be widespread. 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.

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.
