Media Alert: Wi-LAN OFDM Webinar on March 8

CALGARY, ALBERTA--(CCNMatthews - Feb. 28, 2005) - Wi-LAN Inc. (TSX:WIN),
a global provider of broadband wireless communications products and
technologies, will present a special webinar about OFDM on March 8 at
11:00 EST/8:00 PST. Learn everything you ever wanted to know and more
about Orthogonal Frequency Division Multiplexing, the foundation of the
highest performance proprietary broadband equipment, and the foundation
of future WiMAX Forum Certified(1) equipment. If you are interested in
WiMAX, broadband wireless or even Wi-Fi, you should participate in this

OFDM is the underlying technology that will enable the metropolitan area
network (MAN) and true mobile wireless networking. Join Wi-LAN's Ron
Murias, Manager of Applied Research and Development, as he takes you
into the world of OFDM.

Wi-LAN's Wideband OFDM (W-OFDM) is a transmission scheme that enables
data to be encoded on multiple high-speed radio frequencies
concurrently. This allows for greater security, increased amounts of
data being sent, and the industry's most efficient use of bandwidth.
W-OFDM is the basis of the IEEE standard 802.11a, which is the
foundation of the proposed IEEE standard 802.16. It is a patented
technology in the United States under patent number 5,282,222 and in
Canada under patent number 2,064,975. W-OFDM technology is currently
used in Wi-LAN's broadband wireless access systems.

W-OFDM enables the implementation of low power multipoint RF networks
that minimize interference with adjacent networks. This reduced
interference enables independent channels to operate within the same
band, allowing multipoint networks and point-to-point backbone systems
to be overlaid in the same frequency band.
