Nortel Achieves First Simultaneous High-Speed Uplink Mobile Calls

Paris (ots/PRNewswire)

- Power of Combined HSUPA and HSDPA to be Demonstrated at 3GSM
World Congress
Nortel(1) (NYSE: NT ; TSX: NT) has successfully achieved the
industry's  first simultaneous uplink and downlink high-speed
wireless calls between two  mobile devices at uplink speeds four
times faster than current UMTS services.
Nortel's demonstration - planned to be repeated at next week's
3GSM World Congress in Barcelona - uses Nortel's commercial UMTS Base
Transceiver Station and Aeroflex's TM500 handset simulator to
exchange VOIP, videos and files at uplink speeds of 1.4 Mbps.
This achievement illustrates the potential viability of
next-generation wireless technologies for high-bandwidth applications
between mobile devices such as VOIP, video streaming, real-time
high-definition mobile gaming and large file exchange. High-speed
uplinks are particularly valued by media agencies transferring
high-definition images and video content from locations with no
broadband wireline access.
Nortel's HSDPA technology is already being rolled out by operators
to improve the downlink capacity of commercial 3G networks. Nortel's
HSUPA is expected to be available from the beginning of 2007 and to
deliver a higher uplink throughput, reduced latency, and higher
capacity, with a software upgrade of commercial networks.
"The successful demonstration of simultaneous HSUPA and HSDPA
across our commercially available equipment highlights Nortel's
continuous drive for technological innovation within wireless
broadband markets," said Jean-Luc Jezouin, vice president GSM&UMTS
Products, Nortel. "Nortel is committed to providing today's wireless
operators with simple, cost-effective solutions that improve the
quality and range of services to subscribers to maximize
opportunities for increased revenues."
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 achieved the industry's first HSDPA
call at 3.6 Mbps in December 2005, and industry-first UMTS-HSDPA call
in the 900 MHz band in January 2006.
Nortel has worked with a number of wireless operators on HSDPA
trials and deployments, including EDGE Wireless in the US, SKT and
KTF in Korea, SOFTBANK Group's BB Mobile in Japan, mmO2, Orange,
Vodafone (at CeBIT 2005 in Hanover, Germany), Partner Communications
in Israel, and Mobilkom Austria.

announced or filed financial results and resulting negative
publicity; the existence of material weaknesses in Nortel's internal
control over financial reporting and the conclusion of Nortel's
management and independent auditor that Nortel's internal control

impact Nortel's ability to report its results of operations and
financial condition accurately and in a timely manner; the impact of
Nortel's and NNL's failure to timely file their financial statements
and related periodic reports, including Nortel's inability to access

changes, including the termination for cause of Nortel's former CEO,
CFO and Controller in April 2004; the sufficiency of Nortel's
restructuring activities, including the work plan announced on August
19, 2004 as updated on September 30, 2004 and December 14, 2004,
including the potential for higher actual costs to be incurred in

conditions, particularly in emerging markets and including interest
rate and currency exchange rate fluctuations; the impact of
rationalization and consolidation in the telecommunications industry;
changes in regulation of the Internet; the impact of the credit risks
of Nortel's customers and the impact of customer financing and
commitments; general stock market volatility; negative developments
associated with Nortel's supply contracts and contract manufacturing
agreements, including as a result of using a sole supplier for a key
