Cameroon Telecommunications Purchases Wi-LAN's W-OFDM Based Products for Urban Non-Line-of-Sight Networks


Calgary, Canada - January 30, 2003 - Wi-LAN Inc. (TSE:WIN), a global innovator of high-speed wireless data/Internet communications, today announced it has sold $1.1 million (US$745,000) of Wi-LAN's W-OFDM based LIBRA fixed wireless access products and accessories to Cameroon Telecommunications B.P. (Camtel), the national telecommunications carrier for the Republic of Cameroon. The contract is for Wi-LAN to provide and install its industry-leading non-line-of-sight LIBRA products and accessories for Camtel's wireless telecommunications networks in the Cameroon cities of Douala and Yaounde. Additional sales of Wi-LAN products are expected to follow as Camtel moves into further phases of its network buildout.

"Camtel chose Wi-LAN's LIBRA 3000 products for their networks largely because the W-OFDM technology solves many of the practical problems associated with the many non-line-of-sight installations that are necessary in the heavily treed and hilly topography of Cameroon," said Nico Roelofsen, Vice President, Global Sales, Wi-LAN Inc. "This, combined with the very high spectral efficiency of the products, translates into more customers per cell-site, maximum usage of valuable licensed spectrum and higher effective data transmission rates.">

LIBRA, based on Wi-LAN's patented W-OFDM (Wide-band Orthogonal Frequency Division Multiplexing) technology, provides non-line-of-sight capability that has been proven in various commercial networks, increasing fixed wireless access subscriber coverage, from conventional levels of 50% or less, to levels that can exceed 90%. LIBRA's flexible architecture supports full or half duplex operation, is fully redundant, supports T1 and E1 voice networks, and has tiered service management and user-friendly network management, all in an easy to install, weatherproof, single unit design.

"We are very pleased to have won this contract with Camtel in a competitive bidding process," said Dr. Sayed-Amr El-Hamamsy, President and Chief Operating Officer, Wi-LAN Inc. "Camtel is a very innovative and forward-thinking organization and they require Wi-LAN's very reliable, high-performance equipment to meet their wireless telecommunications requirements in very challenging non-line-of-sight environments. This is our first contract with a national telecommunications carrier in Africa, and we are seeing interest from several other African carriers as they seek economic and reliable means to improve high-capacity telecommunications access for their customers.

The LIBRA product series, which includes the LIBRA 3000, is the third generation of Wi-LAN's highly reliable, field-proven, non-line-of-sight commercial W-OFDM products, which have been deployed in networks in more than 20 countries. LIBRA is offered in 3.5 MHz, 7 MHz and 14 MHz channel widths, in various frequencies covering the international 3.5 GHz licensed spectrum. The series meets the needs of service providers who have obtained spectrum licenses from government licensing bodies in more than 40 countries..

LIBRA 3000 is certified for use in the majority of telecommunications markets where 3.5 GHz licensed spectrum is available for commercial telecommunications applications, having received the CE Mark indicating the product conforms to the standards of the European Telecommunications Standards Institute (ETSI). Certifications for other relevant jurisdictions are expected in due course. LIBRA supports both point-to-multipoint and point-to-point applications, and the LIBRA Customer Premises Equipment (CPE) can be configured with either an integrated antenna or an external antenna, making the system more flexible and scalable. Improved security is built in through Wi-LAN's proprietary W-OFDM technology, user-configurable data scrambling and formatting, individual identification codes, VLAN tagging and IP filtering, making a LIBRA network one of the most robust solutions available in the market today. Installation and network setup is greatly simplified, with quick start menus and PDA support eliminating the need for a laptop computer to configure and install the system. LIBRA also offers tiered service management through CIR/MBR (Committed Information Rate / Maximum Burst Rate). The lightweight single unit design eliminates the need for expensive accessories and coaxial cable, is faster and less expensive to install, and can be mounted indoors or outdoors without the need for any climate control.

The current hardware is capable of supporting several generations of enhancement to the system software. Features such as dynamic modulation, dynamic power control, and additional network management features are being made available, as the market requires, via over-the-air software upgrades. Also, current products have a migration path to future products based on the emerging IEEE 802.16a (North America) and ETSI BRAN HiperMAN (European and international) standards.

For service providers offering broadband wireless access, Wi-LAN's LIBRA products offer superior multipath robustness, improved Non-Line-of-Sight performance and high spectral efficiency, which translates into more customers per cell-site, maximum usage of valuable licensed spectrum and higher effective data transmission rates. LIBRA operates at an unprecedented throughput of up to 192 megabits per second per six-sector cell, and has a transmission range up to an estimated 40 kilometers in a line-of-sight point-to-point configuration, and 24 kilometers in a line-of-sight point-to-multipoint configuration. LIBRA products include access points and customer premises equipment, and can be used in broadband access applications alone or in combination with wired alternatives. Using a cellular network design, Wi-LAN's solution can easily serve a growing customer base. Network cells can be expanded quickly and cost effectively. Through the scalability and flexibility of LIBRA products, network operators can start small and expand, allowing a quick return on investment and early profits with relatively low capital requirements.

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.
