AT&T Reduces Dropped Call Rate in San Diego by 25% and Launches Microsite to Show San Diego’s Local Network Upgrades

san diego, calif., April XX, 2012 AT&T* continues to drive investment and innovation to improve voice and data performance on its network. From 2009 through 2011, AT&T invested nearly $700 million in its wireless and wireline networks in the Greater San Diego area. Those investments are paying off in strong service performance, including a reduction in the dropped call rate in the San Diego area by 25 percent, keeping more wireless calls connected.

As part of the drive to deliver the nation’s best mobile internet experience, AT&T has made more than 1,075 wireless network upgrades in the San Diego area since the beginning of 2011. Enhancements through April 10, 2012 include:

·         Activating approximately 20 new cell sites or towers to help improve network coverage.
·         Enhancing nearly 20 cell sites to provide faster mobile Internet speeds.
·         Deploying faster fiber-optic connections to nearly 475 cell sites. Combined with HSPA+ technology, these deployments enable 4G speeds.**
·         Adding capacity or an extra layer of frequency to cell sites – like adding lanes to a highway – with the addition of nearly 575 of these layers, or “carriers.”
In addition, AT&T officially launched 4G LTE service in the San Diego area on January 8, 2012.***

And, AT&T has now launched the new “focus: San Diego” microsite, which is dedicated to providing San Diegans a birds eye view of these network enhancements. Updated weekly, the microsite provides an unparalleled view, unlike any other in the industry, of what AT&T is doing to enhance the customer experience.
