AT&T Customers Get More Mobile Broadband Coverage in Washington County, Tennessee

March 16, 2010   JOHNSON CITY, TN - As part of its continuing network investment to support growing demand for advanced mobile devices and applications, AT&T today announced the activation of a new 3G cell site in Washington County that will enhance coverage for area residents and businesses. The new cell site is located five miles north of Johnson City near Kingsport Highway between Johnson City and Gray and also boosts coverage along Highway 36 and Carroll Creek Road. With 3G speeds, AT&T customers can surf the Web, download files faster, and enjoy the very latest interactive mobile applications.

AT&T recently unveiled its Tennessee wireless network plans for 2010, which include the addition of 20 new cell sites and the upgrade of approximately 525 additional cell sites to 3G throughout the state.

"We welcome these efforts to expand the communications infrastructure in our region," said Rep. Mathew Hill. "New cell tower investments enhance our business environment and work to further our goal of creating more and better jobs for this community."

The new cell site is one part of AT&T's ongoing efforts to drive innovation and extend its 3G wireless network - the fastest in the nation, according to independent testing. It is also part of AT&T's ongoing investment to build the broadband networks that will fuel economic growth and create jobs, and enable its customers to quickly access the content, applications and services that matter most to them.

"Our goal is pretty simple: we want you to have an extraordinary experience when you make a call, check e-mail, download a song or video, or surf the Internet on your AT&T device," said Gregg Morton, president, AT&T Tennessee. "As part of the Johnson City community, we're always looking for new opportunities to provide enhanced coverage and our investment in the local wireless network is just one way to accomplish this."

AT&T recently completed a software upgrade at 3G cell sites nationwide that prepares the nation's fastest 3G network for even faster speeds. The deployment of High-Speed-Packet Access (HSPA) 7.2 technology is the first of multiple initiatives in AT&T's network enhancement strategy designed to provide customers with an enhanced broadband experience, both today and well into the future. Faster 3G speeds are scheduled to become available in 2010 and 2011 on a market by market basis as AT&T combines the new technology with our second initiative to dramatically increase the number of high-speed backhaul connections to cell sites, primarily with fiber-optic connections, adding capacity from cell sites to the AT&T backbone network.

"We are fortunate to have leaders like Rep. Hill who work to create a pro-business environment for our area, one that attracts investment and encourages build out of our telecommunications networks," said Alicia Summers, director of the Northeast Tennessee Valley Regional Industrial Development Association.

"We continue to work aggressively to improve our network infrastructure throughout Washington County to improve the quality of our services," said Jim Thorpe, vice-president and general manager for AT&T Mobility and Consumer Markets in Kentucky and Tennessee. "We're working to make this possible by adding new wireless coverage and offering exciting products to help our customers stay connected with their world, at home and on the go."

AT&T's 3G mobile broadband network is based on the 3rd Generation Partnership Project (3GPP) family of technologies that includes GSM and UMTS, the most open and widely used wireless network platforms in the world. AT&T offers 3G data roaming in more than 115 countries, as well as voice calling in more than 220 countries.
