Wi-LAN'S PATENTED W-OFDM TECHNOLOGY INCORPORATED INTO UNIVERSAL WirelessMAN STANDARD

02/04/2003

 

Semiconductor Companies, Intellectual Property Providers and Other Broadband Wireless Equipment Providers are Invited to Join Wi-LAN in Implementing IEEE Standard 802.16a

CALGARY, Canada - February 4, 2003 - Wi-LAN Inc. (TSE:WIN), a global provider of broadband wireless communications products and technologies, today announced that the Institute of Electrical and Electronics Engineers (IEEE) "WirelessMAN" Standard 802.16a, incorporates Wi-LAN's patented W-OFDM (Wide-band Orthogonal Frequency Division Multiplexing) technology. Wi-LAN is first to market with Standard 802.16a-like products and is dedicated to advancing the implementation of this standard. Wi-LAN encourages all interested parties, including semiconductor companies, intellectual property providers and other broadband wireless equipment providers, to join Wi-LAN in the implementation of IEEE Standard 802.16a.

Wi-LAN has a non-exclusive agreement with Fujitsu Microelectronics America (FMA) to develop Standard 802.16a System-on-Chip solutions.

"With the conclusion of the IEEE Standard 802.16a we are much closer to achieving the full potential of broadband wireless applications and devices," said Keith Horn, FMA's vice president of marketing. "Fujitsu can now move forward with Wi-LAN to design standard-compliant, high-performance and highly integrated System-on-Chip solutions and offer them at a low cost that will help to ensure broad market acceptance of this very promising technology." The experience Wi-LAN has gained in implementing W-OFDM based LIBRA products makes Wi-LAN the leader in Standard 802.16a implementation. Wi-LAN's proprietary LIBRA Broadband Wireless Access (BWA) products provide a working commercial model of the W-OFDM based physical layer of Standard 802.16a. LIBRA has been deployed in networks in almost 30 countries and is designed for a seamless transition to Standard 802.16a.

"Wi-LAN's technology team has worked hard with other IEEE members to finalize IEEE Standard 802.16a, and we have developed our LIBRA products in parallel with the development of the standard", said Dr. Sayed-Amr El-Hamamsy, president and chief operating officer, Wi-LAN Inc. "With LIBRA, the only existing product line that incorporates the W-OFDM based physical layer of Standard 802.16a, we can promise customers a seamless transition to Standard 802.16a products, and we have demonstrated the expertise necessary to assist other companies to implement and market Standard 802.16a solutions."

The IEEE Wireless Metropolitan Area Networks (WirelessMAN) Standard 802.16a, announced on January 30, 2003, defines a standard for BWA systems operating in radio frequencies from 2 to 11 GHz. Although Standard 802.16a specifies three alternative physical layers (PHYs), it is the W-OFDM based PHY that is intended for mainstream applications. The emerging European equivalent to Standard 802.16a, the ETSI BRAN HiperMAN standard, will incorporate Standard 802.16a's W-OFDM based PHY, making W-OFDM the worldwide standard for BWA systems.

"There are no words to describe the feeling one gets when he sees something that he helped invent become a global standard," said Dr. Hatim Zaghloul, chairman and chief executive officer, Wi-LAN Inc. "Ever since W-OFDM's co-inventor, Dr. Michel Fattouche, and I filed the W-OFDM patents in the early 1990's, Wi-LAN has worked towards this day. I believe the IEEE Standard 802.16a, and its European equivalent, the emerging ETSI BRAN HiperMAN standard, will become the basis for fourth generation mobile systems. These mobile systems are being designed to have data capacity in excess of 10 Mbps, and this will facilitate a host of high bandwidth applications, which are not possible with current technologies. W-OFDM will then be truly ubiquitous."

The W-OFDM Advantage
W-OFDM is a variation of OFDM that further improves its characteristics. The signal reception is corrected for distortions, allowing greater transmission speeds, and the signal is processed to maximize the range and multipath resistance. W-OFDM allows lower-power, multipoint radio frequency (RF) networks to be implemented, minimizing interference with adjacent networks.

W-OFDM effectively permits several independent channels to operate within the same frequency band, allowing multipoint networks and point-to-point backbone systems to be overlaid on one another. Less disruption of adjacent users and insensitivity to external noise means that high-speed multipoint data networks can be simply and rapidly deployed. These systems are tolerant of changes in the RF environment, limiting maintenance requirements, and the systems can be easily and economically expanded to meet the service provider's growing business.
