Nortel Secures Wireless Network Expansion, 3G UMTS/HSDPA Trials with Edge Wireless.

TORONTO -- Technology to Boost Network Capacity, Allow for Delivery of Advanced Wireless Broadband Services

Nortel (NYSE:NT)(TSX:NT) announced today that it has been selected by Edge Wireless, LLC, to expand its wireless voice and data network in four states across western United States. Nortel's GSM/GPRS/EDGE technology has enabled Edge Wireless subscribers to receive advanced services such as Web browsing, streaming audio and video, multimedia messaging, VPNs and other high-speed wireless broadband services.

In addition, Nortel and Edge Wireless will begin UMTS and HSDPA 3G field trials this month to demonstrate video streaming, gaming, web browsing and FTP downloads at speeds reaching 1.5 Mbps, which is similar with DSL or a cable connection.

"Our network expansion and UMTS/HSDPA trial are essential to ensuring our customers have the highest quality service and most advanced applications on the market today and into the future," said Donnie Castleman, president and chief operating officer, Edge Wireless. "We chose Nortel as a supplier because of its leading wireless broadband technology and extensive experience in deploying UMTS networks and providing 'best-in-class' service."

"Nortel is pleased to work with Edge Wireless as it evolves its network and prepares for the delivery of the additional advanced wireless broadband services, including UMTS/HSDPA, reliably and quickly," said Peter MacKinnon, president, GSM/UMTS Networks, Nortel. "Nortel's wireless technology helps operators increase revenue potential by leveraging existing network investments and supporting the delivery of high-speed, sophisticated services subscribers desire."

Under the terms of the agreement, Nortel will continue to supply Edge Wireless with new radio base stations and high-capacity base station controllers, switching, GSM/GRPS/EDGE software, and professional services including installation, maintenance, and support. Nortel will also deploy its UMTS/HSDPA Release 4 (R4) technology, which continues Edge Wireless' evolution to a packet switched network.

Nortel's GSM/UMTS-based solutions are HSDPA-ready and designed to easily upgrade to support HSDPA through a software installation. This gives operators the flexibility to more cost-effectively upgrade their networks as needed to boost capacity to meet market demand for wide area broadband wireless data services.

Nortel achieved the industry's first HSDPA mobile call in January 2005. Nortel and LGE completed the first live test calls using a commercial handset solution for HSDPA in March 2005. In June 2005, Nortel became the first wireless network supplier to complete the TL9000 registration standard for Quality Management System Requirements and Measurements across its HSDPA, UMTS and GSM wireless infrastructure solutions.

Nortel has worked with a number of wireless operators on HSDPA trials and deployments in 2005, including SKT and KTF in Korea, SOFTBANK Group's BB Mobile, mmO2, Orange (at 3GSM World Congress 2005 in Cannes, France), Vodafone (at CeBIT 2005 in Hanover, Germany), Partner Communications in Israel, and mobilkom austria.

Nortel has designed, installed and launched more than 300 wireless networks in over 70 countries. Nortel was the industry's first supplier with wireless networks operating in all advanced radio technologies and is the only end-to-end provider of all next generation wireless solutions.
