The first part of the strategy was HSPA+ which is currently deployed across AT&T’s wireless network. The HTC Inspire 4G, The Samsung Infuse 4G and the Motorola Atrix 4G all run on the HSPA+ “4G” network. The forthcoming LG Thrill (Optimus 3D) will also come to the HSPA+ network.
HSPA+ is an upgraded version of the current technology deployed by AT&T. It’s definitely a noticeable increase in speed however it’s nowhere close to the speeds we are seeing on Verizon Wireless’ 4G/LTE network. de La Vega, said in January that over the summer AT&T would start turning on their LTE network and of course we are going to see devices that will go hand in hand with that technology.
More after the break
It’s important to note right now that a lot of Verizon Wireless customers have noticed a problem in handing off from 4G/LTE to 3G where their phones will drop calls and or data. AT&T Wireless customers won’t have this problem because the hand-off across existing GSM networks and LTE is a natural transition and smooth transition for users.
AT&T will launch their LTE service in Atlanta, Chicago, Dallas, Houston and San Antonio. AT&T only said that the service would be available sometime during the summer.
