AT&T 3G MicroCell is expected to be made available next week in select markets which include Atlanta, San Antonio, Seattle and North Carolina. However, the device may be unveiled in more cities if the company plans to launch it on a larger scale. AT&T 3G MicroCell is a Cisco-made device that like most other femtocells, creates a short-range cellular link that then uses the owner’s home internet connection to send both calls and data.

Microcell will differentiate itself from others by supporting 3G calls as well as data for those phones that don’t have Wi-Fi. Usually these devices have an up-front price and sometimes a small subscription fee that promises extra calling time when connected to the femtocell. Carrier files have already suggested iPhone support for the 3G MicroCell as a network choice. AT&T 3G MicroCell’s pirce is yet to be confirm.
