AT&T to Invest in its California Network Enhancing Service to Communities across the State

AT&T to Add More Than 200 New Cell Sites and Upgrade Nearly 320 Sites to 3G

AT&T* today unveiled its California network expansion plans for this year, targeting to add more than 200 new cell sites throughout the state, and upgrading nearly 320 more cell sites to 3G. AT&T's expansion efforts come as more and more people's lives become increasingly mobile and fast-paced, and to address the growing demand for advanced wireless data products and services.

The expansion of its 3G wireless broadband network — the nation's fastest, according to recent data compiled by leading independent wireless research firms — is part of AT&T's ongoing effort to build the broadband networks that will create jobs and fuel economic growth, and enable its customers to access the content, applications and services that matter most to them.

"Investment in the State's wireless broadband network is critical to keeping California competitive and providing our citizens with the best technology," said Senator Alex Padilla (D- San Fernando Valley), Chair of the Senate Energy, Utilities and Communications Committee. "Expanding and enhancing the wireless broadband network extends the benefits of broadband access to many consumers who are relying more and more on wireless technology to access the Internet."

Today's announcement builds on AT&T's 2008 wireless investment in which it added 157 new cell sites in California and upgraded 1,031 existing sites to 3G. From 2006 to 2008, AT&T's total capital investment in its California network was nearly $7.9 billion.

"We continue to make significant investments in California to deliver dependable, high speed wireless access in more places for consumers and business customers who need to stay connected to work, family and friends," said Ken McNeely, president, AT&T California. "Our ongoing investments in California will help us fulfill this vision while ensuring that our state has access to the advanced wireless broadband services that help drive economic growth."

The AT&T 3G network opens the door to a new era of advanced mobile services, devices and feature-rich audio and video content, such as AT&T Video ShareSM, a first-of-its-kind technology that allows users to share live video during a wireless call.

"Our number one priority in 2009 is to continue to enhance the wireless network so our customers have a top notch experience every time they make a call, check an e-mail or surf the Internet on their AT&T device," said Fred Devereux, regional president, AT&T West.

AT&T's wireless network is based on GSM (Global System for Mobile Communications) technologies, the most open and widely used wireless network platform in the world. As a result, only AT&T can offer 3G data roaming in more than 70 countries, as well as voice calling in more than 200 countries, in addition to AT&T's continuous 3G expansion in the U.S. AT&T's 3G network is now available in nearly 350 U.S. major metropolitan areas.

AT&T operates 252 AT&T-owned retail locations in California. AT&T's products and services are also available at a number of other authorized dealers and national retail locations.
