AT&T Doubles Capacity Speeds Up 3G Before Going to HSPA+ and LTE

AT&T has doubled the existing speed in two test markets via software upgrades will do the same in all its markets.

AT&T  will start migrating its 3G networks to HSPA+ technology, which would offer peak download speeds of up to 21Mb/s.

In March, AT&T announced plans to invest between US$17 billion and US$18 billion this year, with its mobile operation earmarked to receive a significant proportion of this sum.

AT&T will eventually move on to LTE technology later than Verizon Wireless, which plans to commercially launch LTE networks next year.

"We expect AT&T's results to reflect wireline continuing to be pinched by the weak economy, while certain segments of the wireless business remain resilient," JP Morgan analyst Mike McCormack wrote in a report.
