Business Editors/High-Tech Writers

DALLAS--(BUSINESS WIRE)--May 28, 2003

Cincinnati Bell Wireless has selected Nortel Networks (NYSE:NT)(TSX:NT) to plan, design and deliver a GSM (Global System for Mobile Communications) and GPRS (General Packet Radio Service) core wireless data network.

Under an agreement announced today, Nortel Networks will provide circuit and IP (Internet Protocol) core networking equipment for an overlay of Cincinnati Bell's existing TDMA wireless network spanning Ohio, Kentucky and Indiana. The upgrades will position Cincinnati Bell Wireless to drive increased network capacity and reduced cost of transporting network traffic, and to offer new data services.

"Cincinnati Bell has a very proud legacy as a leading provider of data services," said Dennis Hinkel, senior vice president, Network Planning and Operations, Cincinnati Bell. "We are now taking our expertise in data to the next level as we role out next generation wireless capabilities that will provide new services for our customers and ensure consistent voice and data capabilities."

Nortel Networks Univity GPRS Wireless Data Network equipment supports data services like Web browsing, streaming audio and video, multimedia messaging, location-based services, m-commerce, Virtual Private Networks (VPNs), and other high-speed wireless data services. These types of personalized service offerings can position Cincinnati Bell to attract new customers, enhance loyalty with existing customers, and drive new revenues.

"We are very proud to have been selected to deploy the IP core network that will position Cincinnati Bell to meet growing subscriber demand for wireless voice and data services," said Alan Pritchard, vice president, GSM/GPRS/EDGE Americas, Nortel Networks. "This TDMA to GSM/GPRS upgrade represents another new core IP customer and continued momentum for Nortel Networks as a leading core provider."

Nortel Networks is an industry leader in migrating TDMA wireless networks to support more efficient and higher-capacity GSM, GPRS and EDGE technologies. Earlier this year, Nortel Networks secured a contract with Eastern New Mexico Rural Telephone (ENMR), a rural provider of wireless services in eastern New Mexico and western Texas. At the end of 2002, CORR Wireless, Alabama's first digital wireless provider; Union, a regional wireless provider servicing subscribers in Wyoming, Colorado and Utah; and Highland Cellular, a Cellular One wireless provider serving West Virginia, selected Nortel Networks to migrate their TDMA networks to GSM/GPRS technologies. In June 2002, Triton PCS, serving the southeastern United States and EDGE Wireless, serving the western United States, selected Nortel Networks for their GSM/GPRS network builds.

GSM and GPRS equipment to be deployed for Cincinnati Bell includes Univity Gateway GPRS Service Node (GGSN), Univity GSM Serving GPRS Service Node (SGSN), and Univity Mobile Switching Center (MSC). Nortel Networks GSM infrastructure is designed to easily support GPRS and EDGE with only card and software upgrades, which helps minimize capital expenses and protects network investments when migrating to next generation technologies.

Nortel Networks will also provide on-site network support, logistical planning, installation and support services through its "Build, Launch and Transfer" program. This program, developed to minimize the challenges of launching new wireless technology and get the most out of existing network resources, will assist Cincinnati Bell with the transition to the new GSM/GPRS wireless data network.

Globally, Nortel Networks has deployed 80 GSM/GPRS networks in more than 50 countries, and is supplying GSM/GPRS systems to enable Wireless Data Network services for more than 50 operators. Nortel Networks is the industry's only supplier with Wireless Data Networks operating in all three advanced technologies - GPRS, CDMA2000 and UMTS.
