AT&T Wireless today announced that it has launched Universal Mobile Telecommunications System (UMTS) services in Dallas and San Diego with radio access equipment provided by Ericsson. Ericsson also provided network design and optimization services for today's launch. The UMTS networks will allow AT&T Wireless to increase network capacity, reduce networking costs and increase data speeds for advanced consumer and enterprise wireless services.

Today's launch continues a long relationship between Ericsson and AT&T Wireless to bring advanced third-generation data services to market. The two companies first announced they would work together to migrate AT&T Wireless' networks to 3G in November 2000. In February 2002, the companies made the first live 3G UMTS voice call in the United States. AT&T Wireless and Ericsson began a network trial in Dallas in December 2002 with the first call over a live 1900 MHz UMTS/WCDMA system in the Americas. Ericsson was also a major supplier to the carrier's EDGE system, the first national 3G network in the United States.

"The march to 3G services in North America continues with AT&T Wireless' announcement today of two more UMTS launches," said Angel Ruiz, Ericsson's North American president and chief executive officer. "Ericsson is proud to work with AT&T Wireless to deliver richer consumer offerings and higher network capacity."

AT&T Wireless' UMTS service gives subscribers continuous, high-speed wireless connections. Customers can now use a handset, PDA or laptop to receive streaming audio and video services; create and share video clips; experience richer and more visually compelling content; and connect to critical business information, in most areas throughout these cities. The deployments will also support all IP-based network architecture to streamline network functions significantly.
