AT&T To Upgrade 3G Network with 7.2Mbps HSDPA For New iPhone

Most of you might recall that the launch of the Apple iPhone 3G was preceded by AT&T’s announcement of 3G network upgrades, finally bringing HSPA (HSDPA and HSUPA) to the US. And, now that the third-iteration of the iconic iPhone is soon to come, AT&T has announced yet another round of 3G network upgrades, planning to roll out 7.2Mps HSDPA upgrades for its entire 3G HSPA network in the US!

The upgrade to the much more efficient HSDPA spec will allow AT&T to serve up 3G data speeds at a theoretical max of 7.2Mbps on the downlink, double the current theoretical max of 3.6Mbps. More importantly, it will allow the new iPhone to really work great on the AT&T network. The upgrade to 7.2Mbps HSDPA should increase capacity as well as wireless data speeds, but AT&T is also working to boost capacity through hardware expansion – adding HSPA carriers at some cellsites and upgrading backhaul networks to handle the increased load.
