AT&T has announced the completion of a local initiative to increase the wireless capacity of its third generation (3G) mobile broadband network to 46 cell sites in  the Hampton Roads, VA, area.

The network enhancement includes the addition of new layers of frequency, also known as "carriers," to more efficiently manage available spectrum and increase 3G capacity at local cell sites.

In related news, AT&T announced that it invested nearly $40 million from 2008 through 2009 to complete a local initiative to increase the wireless capacity of its 3G mobile broadband network throughout the Chicago area.

As a result of deploying additional wireless spectrum in the 850 MHz band, local customers are expected to experience improved 3G wireless voice and data connectivity and performance, especially during peak hours.

More than 700 cell towers across the Chicagoland area were updated as part of the spectrum deployment. In addition, more than 40 strategically placed distributed antennas and microcell sites were upgraded to the 850 MHz spectrum in the downtown Chicago Loop to provide additional coverage.
