AT&T’s Kris Rinne, executive vice-president of network planning and architecture, announces that AT&T plans to upgrade its UMTS/HSPA network to enable faster up-link speeds. With HSDPA pushing down-link data at broadband-speeds, AT&T wants to boost their Cingular wireless network’s current UMTS-based up-link speed using HSUPA. The HSUPA software upgrade would enable peak up-link speeds of 1.5Mbps, a considerable improvement on the current UMTS-based upstream speed of around 300Kbps. The upgrade will be rolled out in 58 to 65 US markets over the course of 2007, completing AT&T’s 3.5G HSPA initiative.
