MONTREAL, QUEBEC--(Marketwire - Dec. 5, 2007) - SR Telecom Inc. (TSX:SRX), a leading vendor of broadband wireless access solutions through its WiMAX Forum-certified symmetryMX product line, today announced that its symmetryMX TDD solution received WiMAX Forum certification.

TDD, FDD and WiMAX solutions

Duplexing refers to the way in which data travels in a two-way wireless transmission. The downlink carries information from a Base Station to Subscriber Stations. The uplink carries information in the reverse direction.

FDD (Frequency Division Duplex) requires two distinct channels for transmitting data, in the same time slot, and is commonly used in cellular networks. TDD (Time Division Duplex) requires only one channel for transmitting data, in two distinct time slots, and therefore has higher spectral efficiency.

WiMAX deployments usually use TDD, as it uses siginifcantly less spectrum than FDD and is economical with bandwidth. In addition, it is less complex and less expensive. Fixed WiMAX profiles support both TDD and FDD, while mobile WIMAX profiles support only TDD.
