Wireless from AT&T, formerly Cingular Wireless, is the largest wireless company in the United States, with more than 71 million subscribers who use the nation's largest digital voice and data network. AT&T is dedicated to providing customers with wireless technology designed to enrich their lives.
The new AT&T offers the largest digital voice and data network in the U.S., including service in all top 100 metropolitan areas. We offer our customers a nationwide GSM/GPRS footprint across 100 percent of our service area.
GSM is the world's most popular wireless phone technology used by more than 1 billion people in 200-plus countries around the world. GSM offers customers unparalleled global roaming capabilities, as well as the truest voice quality in wireless.
In 2003, Cingular launched the world's first commercial deployment of wireless services using Enhanced Data rates for GSM Evolution (EDGE) technology. EDGE is a third-generation high-speed mobile data and internet access technology, with average rates that are fast enough to support a wide range of advanced data services, including streaming audio and video, fast Internet access, and large file downloads.
When it comes to technology, AT&T is always looking toward the future. We have launched Universal Mobile Telephone Service in six markets and intend to launch several more in 2005. UMTS is the leading 3G-technology choice today offering potential worldwide coverage and enabling economies of scale, global roaming, and a priority technology for software and applications developers. UMTS is one of the natural forward evolutionary paths for GSM networks.
