AT&T Expands Mobile Broadband Coverage in Darlington

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 Harford County. The new site, located in Darlington, will enhance wireless coverage for area residents and businesses along Flintville Road between Route 1 and the Pennsylvania state line. With 3G speeds, AT&T customers can surf the Web, download files faster, and enjoy the very latest interactive mobile applications.

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.

“During the past several years, we’ve made substantial private investments to provide our customers in Harford County and across Maryland with access to the kind of technology that will stimulate economic growth, inspire innovation, and create jobs,” said J. Michael Schweder, President AT&T Mid-Atlantic. “We remain committed to working with our federal, state, and local leaders to help create a positive economic environment that provides opportunities for companies to continue to invest aggressively in the state.”

From 2007 to 2009, AT&T’s total capital investment in its Maryland wireless and wireless networks was more than $425 million.

“More than ever before, customers look to wireless communications to stay in touch with family, friends and business colleagues,” added Rob Forsyth, vice president and general manager for AT&T in Maryland, Washington, D.C., and northern Virginia. “We’re working to make this possible by adding new wireless coverage in Darlington and offering exciting products to help our customers stay connected with their world, at home and on the go.”

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 mobile 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.

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.
