AT&T has announced  LTE and HSPA+ upgradable modems, USBConnect Adrenaline from LG will be LTE-capable while the USBConnect Shockwave from Sierra Wireless will offer HSPA+ connectivity.

 The AT&T USBConnect Adrenaline from LG will be AT&T's first LTE-upgradeable device. According to company statement, a simple software upgrade via AT&T Communication Manager or AT&T Global Network Client will be all that is required to enable it to work on the LTE network when available.

Featuring a sleek casing and smooth finish, Adrenaline is equipped with an internal antenna, plug and play functionality and multiple OS support that will keep users connected and on-the-go. Adrenaline also features built-in GPS for enterprise applications, a multi-color LED status indicator and a MicroSD memory card slot supporting cards up to 32 GB of storage.

"We have purposefully planned our path to LTE to create a wireless network where the transition from 3G does not give customers wireless whiplash," said Michael Woodward, vice president, Mobile Phone Portfolio, AT&T Mobility and Consumer Markets. 

Built ready to run on AT&T's planned HSPA+ network upgrade, AT&T USBConnect Shockwave from Sierra Wireless is the first LaptopConnect device from AT&T to do so. AT&T expects to upgrade to this next evolution of 3G network technology by the end of 2010.
