AT&T Inc.’s wireless division is testing an upgrade to its HSDPA network that the carrier says will dramatically increase uplink speeds.

According to Kris Rinne, AT&T’s executive vice president of network planning and architecture, the company will be rolling out the software upgrade over the course of 2007 and will likely begin offering compatible PC cards by mid-year.

HSDPA focuses on downlink speeds, and the HSUPA upgrade speeds the uplink from the device to the network; AT&T’s wireless network would then be considered HSPA. Rinne said that from current uplink peak speeds of 384 kilobits per second and averages of 150 to 200 kbps, the HSUPA upgrade will put uplink peak speeds in the range of 1.5 megabits per second.
