Siemens Selected to Supply High-Speed Third Generation Mobile Network to Cingular Wireless

Siemens Communications, Inc., today announced that it has been chosen to assist Cingular Wireless with its nationwide deployment of a true third generation (3G) high-speed UMTS (Universal Mobile Telecommunications System) network. The multi-year agreement includes UMTS radio and core networks, as well as significant GSM/GPRS/EDGE market expansions. Siemens will also supply an enhanced version of UMTS called High Speed Downlink Packet Access (HSDPA), which will further increase data rates to a theoretical peak of up to 14.4 Mbps. As an existing supplier to Cingular, Siemens is building on its strategic relationship with the largest wireless carrier in the United States to provide a wide range of UMTS and HSDPA technology solutions and services.

The migration to UMTS and HSDPA will enable Cingular to provide significant customer benefits. These range from high-speed access to the Internet and wireless video and audio for business customers as well as a wide variety of services such as high-resolution digital image transfer, full-motion video, and advanced interactive gaming for consumers.

Siemens is one of the world's leading providers of 3G technology, with more than 30 existing UMTS infrastructure contracts. Today, it is estimated that one out of every two commercial UMTS networks worldwide relies on technology from Siemens and its partner NEC, which represents coverage for 90 percent of all 3G subscribers worldwide.

"These wireless network enhancements will enable our customers to receive wireless broadband connections in places they've never been able to before," said Kris Rinne, Chief Technical Officer for Cingular Wireless. "Siemens will help us deliver 3G products and services to people across the country."

"Siemens is excited to be providing end-to-end third generation wireless solutions for Cingular Wireless and we look forward to continuing our strong relationship with the top wireless company in America," said Andy Mattes, President and CEO of Siemens Communications, Inc. "Our tremendous breadth and depth of experience and consistent performance are strong assets that will benefit Cingular."
