AT&T Brings South Florida's Fastest Wireless Broadband Network to the Treasure Coast

Company Delivers Ultrafast Mobile Access to Interactive Content and Mobile Applications

Boca Raton, Florida, October 30, 2007

AT&T wireless users in Martin and St. Lucie counties now have access to South Florida's fastest wireless broadband network — the AT&T third-generation (3G) network. AT&T Inc. (NYSE:T) announced today the expansion of 3G service to the Treasure Coast.

AT&T's 3G network is the fastest wireless broadband network in South Florida based on drive-test results from a leading independent wireless research firm that provides performance measurements for the wireless industry. The network delivers typical download speeds ranging from 600 to 1,400 Kbps. Customers using an AT&T 3G handset can download a game or ringtone or access e-mail in a fraction of the time that it used to take.

The nation's largest wireless carrier rolled out its South Florida 3G network in Miami-Dade, Broward and Palm Beach counties last fall and in the Florida Keys earlier this month. The company is excited to extend the network to the Treasure Coast.

"With the launch of our 3G network in Martin and St. Lucie counties, AT&T wireless customers will benefit from the powerful combination of a superfast network and a portfolio of cutting-edge 3G devices that quickly deliver interactive content and applications," said Rich Guidotti, vice president and general manager for AT&T's South Florida wireless operations.

The AT&T 3G wireless broadband network allows customers to take advantage of advanced, on-the-go wireless services such as:

  • Video Share — A groundbreaking, first-of-its-kind service in the U.S. that allows users to share live video over wireless phones while carrying on a voice call.
  • CV — An on-demand streaming video service that lets users watch video clips of their favorite TV shows, movies, news, weather, sports and more.
  • AT&T Mobile Music — An integrated music experience that allows one-click access to a complete suite of music-related content, including the most comprehensive music subscription service of its kind in the U.S.

The AT&T 3G network also mobilizes businesses at high speed. AT&T LaptopConnect — which simply requires a LaptopConnect card or a laptop with embedded 3G capability, software and an AT&T data plan — gives businesses the ability to use their laptops at DSL-like speeds to access business applications, including personal and business e-mail, corporate networks/intranets, back-end business applications and the Internet.

AT&T provides 3G services in more than 200 metropolitan areas, with plans to expand to additional markets by the end of the year. AT&T has invested more than $800 million in its Florida wireless network since 2005 to improve coverage and expand its 3G footprint throughout the state.

"This expansion is evidence of our ongoing commitment to investing in the state of Florida," said Marshall Criser III, president of AT&T Florida. "The investments by AT&T will have a positive impact at both the state and community level, in addition to the benefits that our customers will receive."

About AT&T's 3G Technology
AT&T's 3G network is the first widely available service in the world to use HSDPA (High Speed Downlink Packet Access) technology. HSDPA is the high speed evolution of GSM/EDGE (Global Systems for Mobile Communications/Enhanced Data Rates for Global Evolution), which shares a common core network. As a result, in areas in which the AT&T 3G network is not available, customers will automatically receive service on the company's EDGE network.

AT&T's EDGE network is the largest high speed wireless data network in the country and is available to 270 million people in more than 13,000 cities and towns and in areas along 40,000 miles of highways. The EDGE network provides average data speeds up to 135 Kbps.

Additionally, because AT&T's network is based on GSM — the most widely used wireless technology in the world — customers have unparalleled global roaming capabilities. They can make calls on six continents and in 190 countries and use data functions in more than 135 countries.
