7th August ,2004

Wi-LAN Inc., a global provider of broadband wireless communications products and technologies, today announced it has successfully demonstrated its LIBRA 5800 TM operating in a full mobility environment, including both high speed (vehicular) and seamless hand-off capability. This demonstration was prepared for a senior delegation from one of the world’s leading electronic companies, who cannot be named due to confidentiality. This demonstration marks another significant milestone towards Wi-LAN’s long time vision of applying its Wide-band Orthogonal Frequency Division Multiplexing (W-OFDM) technology in 4th Generation (4G) cellular Networks.

The demonstration is performed using equipment based exclusively on Wi-LAN’s W-OFDM expertise. Backhauled by Wi-LAN’s LIBRA 3000, two LIBRA 5800 TM Access Units with hand-off capability provide wireless connectivity of 32 Mbps to a Mobile Unit traveling in excess of 100 km/hour (62 mph). The demonstration was shown over a 3 km stretch of highway north of the Calgary international airport.

“The hand-off capability in a high speed environment is another significant milestone,” says Dr. Sayed-Amr El-Hamamsy. “The demonstration proves the capability of W-OFDM technology for 4G cellular networks.” Wi-LAN demonstrated its W-OFDM technology in a 110 km/hour (or 70 mph) mobile environment without hand-off back in January 2000.

The LIBRA 5800 TM product line, a joint development between Wi-LAN and Wellink, a leading integrator of high-speed telecommunication systems, is designed to address the growing Intelligent Transportation System (ITS) market, including Public Safety, Homeland Security and onboard multimedia service.

Wi-LAN invites mobile operators and equipment makers to arrange a visit to Calgary to witness a demonstration of this exciting technical breakthrough.

Wi-LAN’s LIBRA 5800 product series now includes an all-inclusive 2-year parts and labour warranty. As well, customers who deploy Wi-LAN’s LIBRA product line are protected by Wi-LAN’s CONTINUITY PROGRAMTM. The core of the CONTINUITY PROGRAM is Wi-LAN’s commitment that any current LIBRA Customer Premise Equipment (CPE) will operate side by side, in the same network, the same cell and even the same sector with future WiMAX Certified* CPE’s. The CONTINUITY PROGRAM will minimize network and revenue disruption and protect customers’ investment in current technology when networks are transitioned to WiMAX Certified equipment. The CONTINUITY PROGRAM offers Wi-LAN customers a solid migration path to Wi-LAN’s Wi-MAX Certified systems, which are expected to be available in the first half of 2005.
