4G to Supersede 3G Technologies in the Future

August 5, 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 PROGRAM(TM). 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(1) 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.
