newsrelease

AT&T* today announced a substantial upgrade of its 3G mobile broadband network in Seattle, Tacoma, Everett, Renton, Auburn, Pierce and King Counties with the deployment of additional wireless spectrum in the 850 MHz band. As a result of this upgrade, local customers should experience better 3G wireless connectivity, performance and enhanced in-building wireless coverage. The enhancement also increases network capacity, and is intended to support ever-growing demand for 3G mobile broadband service.

The high-quality 850 MHz spectrum generally results in better in-building coverage. While specific benefits of the additional spectrum will vary by location, AT&T 3G customers should see improved quality and coverage throughout Seattle, Tacoma and surrounding markets. AT&T technicians nationwide responsible for monitoring network performance for service quality and coverage have seen significant increases in total 3G data traffic in areas where the 850 MHz spectrum has been deployed.

This network enhancement is one part of AT&T’s ongoing efforts to drive innovation by investing to deliver the benefits of smartphones and mobile broadband for customers. More smartphone customers have chosen AT&T over any U.S. competitor, resulting in wireless traffic on the AT&T network that has quadrupled over the past year. This growth includes a volume of smartphone data traffic over the AT&T network that is unmatched in the wireless industry.

“This substantial network upgrade is part of our commitment to continue delivering the nation’s fastest 3G network along with the highest possible levels of service quality and reliability,” said Mike Maxwell, vice president and general manager for AT&T’s wireless unit in the Pacific Northwest. “We know many customers depend on wireless as their primary communications connection to work, family and friends. We’re enhancing our network every day to help customers do more with and get more from their wireless connections.”

Recently, AT&T announced plans to further upgrade its 3G network nationwide with High Speed Packet Access (HSPA) 7.2 technology to deliver considerably faster mobile broadband speeds. The upgrades in the Seattle area are planned to begin in 2010, with completion expected in 2011. Additionally, AT&T is planning to add nearly 1,900 cell sites nationwide this year as well as new backhaul connections across the country to support the increasing volumes of mobile data traffic.

"Investing in our network across Washington is critical to serving our customers both in urban and rural areas. We are proud to offer real choices in service, devices and applications with an expanding network to support all of their needs," said Dan Youmans, AT&T state president of external affairs.

“Private sector investment helps spur innovation and creativity. Expanding access to technology plays a key role in creating greater economic opportunities for consumers and businesses and will help drive the Seattle area to a more prosperous future,” said Washington State Representative Zack Hudgins, who represents the Renton area and serves as Majority Floor Leader and member of the House Technology, Energy and Communications Committee.

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’s 3G network is available in more than 350 major population centers. AT&T also offers 3G data roaming in more than 100 countries, as well as voice calling in more than 215 countries.
