Nortel Demonstrates OFDM, MIMO at Super High Speeds;
Technology to Improve Spectrum Efficiency, Enhance
User Experience, Decrease Operator Costs

OTTAWA--(CCNMatthews - Mar 9, 2005) -

Nortel (NYSE:NT) (TSX:NT) has achieved another wireless technology
milestone, demonstrating a significant increase in data throughput using
beyond 3G (third generation) MIMO (multiple-input, multiple-output) and
OFDM (orthogonal frequency division multiplexing).

The demonstration took place at Nortel's Wireless Technology Lab in
Ottawa. Nortel will highlight its 3G MIMO and OFDM success and recent
learnings from its lab at CTIA Wireless 2005 in New Orleans (Ernest N.
Morial Convention Center, Hall C, Booth #3125) March 14-16.

MIMO and OFDM will make it possible for wireless subscribers to download
bandwidth-hungry applications - large file transfers, streaming video
and mobile gaming - at speeds higher than today's commercial 3G
networks. Nortel has invested in advanced development of OFDM and MIMO
for the past six years and has demonstrated the benefits and commercial
feasibility of these technologies to more than 100 customers.

"Nortel is innovating beyond 3G to develop future wireless broadband
technologies that will leverage existing service provider investments
and enhance the subscriber experience through feature-rich services and
multimedia applications," said John Hoadley, vice president, Next
Generation Wireless Access, Carrier Networks, Nortel. "We believe that
OFDM and MIMO will be vital to service provider success and will be the
foundation of future wireless broadband networks."

OFDM and MIMO together can support up to two times more subscribers than
OFDM alone. This will position service providers to make more efficient
use of existing spectrum.

In Ottawa, Nortel demonstrated large information transfers with peak
data rates at 37 Mbps over a standard 5MHz PCS mobility band, taking
into account noise and fading conditions found on a real-world cellular
network. The test network showed that with OFDM and MIMO, wireless
subscribers can download a 128 MB file in approximately 30 seconds -
four to 10 times faster than today's 3G wireless networks.

OFDM is the base radio technology used by WiFi (802.11) and WiMAX
(802.16). MIMO is an advanced antenna and space-time processing
technology. The first broad deployment of standards-based wireless wide
area networks employing OFDM technology is anticipated in 2006 with the
introduction of WiMAX 802.16e products. In addition, Nortel is also
proposing OFDM/MIMO as its evolution vision beyond HSDPA/HSUPA and CDMA
1xEV-DO into 3GPP and 3GPP2 wireless standards.

In 2001, Nortel completed an extensive propagation trial in central
London, England, proving the feasibility of MIMO to provide substantial
performance gains in an urban deployment. In February 2003, Nortel
demonstrated OFDM and MIMO peak data rates of 20 Mbps over a standard
5MHz PCS band. The recent Ottawa demonstration nearly doubled that

Nortel is an industry innovator and at the forefront of all broadband
access technologies, including wide area cellular, wireline and wireless
LAN. In 2004, Nortel's Wireless Technology Lab in Ottawa filed 62 new
patent applications, and 33 previous applications were granted.

Nortel is a member of many wireless industry and standards bodies,
including the WiMAX Forum, Third Generation Partnership Project (3GPP),
3GPP2, the Cellular Telecommunications & Internet Association (CTIA),
IEEE, the Wi-Fi Alliance, and the Wireless Communications Association

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
(GSM/GPRS/EDGE, CDMA2000 1X and 1xEV-DO, UMTS and WLAN) and is the only
end-to-end provider of all next generation wireless solutions, as well
as edge and core network solutions for IP, ATM and optical transport.
