Industry-First Demo of MIMO in 4G-Enabled Technologies with WiMAX, LTE
BARCELONA, SPAIN -- (MARKET WIRE) -- February 08, 2007 -- At 3GSM World Congress 2007, Nortel(1) (TSX: NT)(NYSE: NT) will challenge the industry to deliver the 4G "Lifestyle" through broad implementation of next-generation, high-speed technologies essential to delivering real-time mobile services such as video and high-definition TV broadcasting.

Nortel will showcase its 4G technologies at 3GSM, the world's largest global show for mobile operators, to be held in Barcelona, Spain February 12-15. Nortel is leading development of new 4G and converged architectures that allow operators to deliver disruptive new services, creating a fourth-generation lifestyle of high-speed, high-quality mobile communications.

At 3GSM, Nortel plans to deliver a demonstration of the industry's first live end-to-end MIMO-powered WiMAX solution, using advanced innovative antenna technology to deliver high-bandwidth applications, such as real-time video, over personal mobile devices. The planned demo will include the Nortel MIMO base station and a variety of WiMAX devices such as a WiMAX DBDM (dual band dual mode) smart phone from LG Electronics using Sequans' chipset; data cards from Kyocera Wireless and ZyXEL using Runcom's chipset; and Intel-based devices. Nortel is developing a robust WiMAX ecosystem which includes infrastructure, chipsets, and devices to support the consumer era of personal broadband and hyper-connectivity.

As part of its 3GSM exhibit, Nortel will also demonstrate a number of real-time high bandwidth applications such as multi-party video conferencing, personal video streaming, video surveillance, VoIP, and instant messaging powered by its next-generation and converged networks.

"Nortel is pioneering the application of OFDM and MIMO which are the underlying technologies for WiMAX, Long Term Evolution and Ultra Mobile Broadband," said Richard Lowe, president, Mobility and Converged Core Networks, Nortel. "Innovation in next-generation technologies is part of Nortel's DNA which means that no one understands the wireless technologies needed to deliver 4G Personal Broadband better than Nortel. At next week's 3GSM conference, we'll deliver more industry firsts with our partners in LTE, WiMAX and IMS to challenge the wireless industry to transform and deliver the fourth-generation lifestyle."

Nortel will perform the industry's first demonstration of a 3GPP LTE (Long Term Evolution) implementation with Collaborative MIMO (also known as Uplink Multi-user MIMO) at 3GSM. In its booth Nortel plans to showcase the performance, capacity and spectral efficiency benefits of LTE with a variety of applications. The LTE demonstration will feature user equipment supplied by LG Electronics as the device partner. Guests can see how LTE can drive greater mobile multimedia adoption with more affordable services for the mass market while increasing profitability for mobile operators. In the uplink, Nortel will demonstrate Collaborative MIMO, a Nortel innovation that will reduce the complexity and cost of the terminals for mass market adoption and increase the uplink capacity of the network to almost twice as many subscribers per cell. This innovation has been accepted into the LTE and WiMAX standardization work.

GSM operators will also discover new solutions to the existing Nortel 2G portfolio - such as new IP Pico BTS for improved indoor coverage - and ways to evolve their networks directly from 2G to 4G.

Nortel CEO Mike Zafirovski, will join fellow chief executives from leading global mobile operators, equipment vendors and content providers in a keynote presentation panel session. The session, titled "Redefining Vendors for Future Success," takes place at 09:00 am on Thursday, February 15.

In "Lifestyle" environment settings - a living room, an office, a cafe - live and highly interactive presentations and demonstrations will showcase Nortel's current and future wireless capabilities across the key areas of:

- Boosting mobile multimedia - understand how Nortel's infrastructure, ecosystems and experience deliver high-speed mobile broadband for businesses and consumers. Includes a variety of demonstrations based on LTE and WiMAX technologies. Nortel will also demonstrate how its efficient backhaul solutions can drive 3G/4G services growth by radically reducing transmission costs.

- Achieving convergence with Nortel IMS, VoIP and IPTV solutions - experience personalized mobile and secure multimedia communications for simpler and richer connectivity across devices and access. Includes making All-IP Voice a reality, extending voice services with IMS voice call continuity (VCC), and true Quad Play (voice, data, video and mobile) solutions powered by IMS.

- Transforming Business with Nortel Global Services - discover new ways to lower costs, create new revenue, maximize network performance, enhance business processes, and optimize the user experience.
