In 2000, the team at Wi-LAN Inc. began work on the BWS 3500 project. This project provides for the development of a two-way data communications product, developed for high-speed wireless access in the 3.5 GHz frequency band.
One of the most exciting applications of BWS technology could be in providing high-speed Internet access to rural communities in projects such as Alberta Supernet. By combining fiber links between communities with broadband wireless distribution within the communities, a cost effective network deployment can be achieved, providing rural communities with the same access to information as their counterparts in larger urban cities. This type of access will have a direct impact on government, school boards, business, First Nations and residential consumers. Wi-LAN's BWS Series will put Alberta, and hence Canada, in a leading position for high-speed wireless access products in the world.
The three major components of the product
are indoor unit (IDU); outdoor unit (ODU) with integrated antenna and
Systems Software. The BWS 3500 delivered modular design can be modified
and utilized in other products. Most of the IDU design and software developed
under this project will be usable in a number of other products in different
frequency bands. Implementations in the 5.8 GHz (UNII), the 2.4 GHz (ISM)
and 2.5 GHz (9 MMDS/MCS) licensed bands will be natural extensions of
this wireless Access Network (WAN) project line.
The BWS 3500 project provides for the first implementation of Wid-band Orthogonal Frequency Division Multiplexing (W-OFDM) technology in a two-way high-speed data capacity communication system with an efficiency of over 3 bits/hertz. The system delivers a 32 Mbps raw data capacity with a throughput of over 22 Mbps in point to multi point application. The initial product had had an occupied bandwidth of 10 MHz making the product suitable for North America and some of the European Countries. As the spectrum availability becomes difficult and expensive in other counties in Europe and Asia, the need for 7MHz and 3.5 MHz bandwidths became apparent.
W-OFDM implementation allows for non-Line of Sight operation, which makes the system unique compared to any other single carrier product out there in the field. Use of W-OFDM allows transmission of closely spaced multiple carriers over the air to combat the problems encountered in multi-path environments and allows for non-line of sight (NLOS) operations, which makes installation in the field much easier, increases coverage for each base station and improves reliability of the system. Operating at an unprecedented throughput of up to 192 megabits per second per six-sector cell, Wi-LAN's BWS Series includes access points and customer premises equipment and can be used in broadband access applications alone or in combination with wired alternatives. The BWS Series also offers an eave-height-integrated antenna and outdoor unit that allows for quick and economical installation of point-to-point and point-to-multipoint applications.
The project is now in the manufacturing
stage. The BWS 3500 product is the first of the series of products that
are planned by Wi-LAN.
