DALLAS -- Western Wireless Corporation (Nasdaq:WWCA - News), a leading provider of wireless communications services to rural America, has awarded Nortel Networks (NYSE:NT - News; TSX:NT - News) a contract estimated to be valued up to $US 90 million to deploy wireless data network equipment to expand coverage across the Western region of the United States.

Nortel Networks will deploy CDMA2000 core and radio access networking equipment to position Western Wireless to increase network capacity, support its growing subscriber base and extend wireless coverage areas across the western United States. Nortel Networks will be the sole supplier of new CDMA equipment for certain of Western Wireless' markets in Kansas, Nebraska, Missouri, Iowa, Arizona, Arkansas, Nevada, California, and Texas.

As announced on May 1, 2003, Nortel Networks has also been selected as the sole supplier of Western Wireless' GSM (Global System for Mobile Communications) and GPRS/EDGE (General Packet Radio Service/Enhanced Data rates for GSM Evolution) roaming network. The GSM deployments will allow Western Wireless to provide roaming services to Cingular Wireless, T-Mobile USA, AT&T Wireless and other GSM operators. Additionally, Nortel Networks will provide installation and integration services for the CDMA and GSM infrastructure as well as Assisted Operation services for the GSM network.

Dual-band GSM core and radio access equipment provided by Nortel Networks will support both the 850 MHz and 1900 MHz radio spectrums to provide seamless voice and data services for subscribers across all of these operator networks.

"We are very pleased to expand on our 12-year relationship with Nortel Networks," said Eric Hertz, chief operating officer, Western Wireless. "Nortel Networks continues to help us meet the changing needs and dynamics of our wireless business, and to build on the high quality wireless services we offer to our subscribers and roaming partners across the nation."

Nortel Networks launched the first commercial CDMA2000 network for Western Wireless in Texas in March 2002.

Dual-band GSM and GPRS (EDGE-ready) infrastructure to be deployed include S8000 and S12000 Base Station Transceiver (BTS), and Mobile Switching Center (MSC) equipment.
