SR Telecom conducted a comprehensive review of available solutions for its WiMAX PHY and concluded that the ADI TS201 is a perfect fit for the signal processing demands of both 802.16-2004 and 802.16e base stations. ADI's commitment to the WiMAX market and its demonstrated expertise in digital signal processing solutions were the other key factors in the decision.

"With this important collaboration, we will be able to produce reliable, feature-rich and future-proof solutions for the global WiMAX market, and help to ensure that the promise of WiMAX is fully realized," said Pierre St-Arnaud, SR Telecom's President and Chief Executive Officer.

"ADI is very pleased that SR Telecom has adopted the TS201 TigerSHARC processor for its WiMAX base station solution," said Jerry McGuire, General Manager, Media Platforms and Service Group, Analog Devices. "Based on our customer feedback, there is a strong demand for more complete solutions for the WiMAX infrastructure equipment market. SR Telecom is uniquely positioned to provide a WiMAX base station because of its extensive real-world experience with NLOS OFDMA deployments. The adoption of the TigerSHARC processor in the early stages of the WiMAX market enables customers to benefit from the high performance and flexibility offered by the TigerSHARC Software Defined Radio (SDR) solution."

SR Telecom's symmetry(TM) product line was the first in the industry to incorporate the advanced technology specified in the 802.16 standards. This technology includes OFDMA, DL/UL sub-channeling, DL/UL closed-loop power control, adaptive modulation up to 64 QAM, adaptive beam steering, TX and RX diversity (Space Time Coding and Maximum Ratio Combining), FEC, Hybrid ARQ, collision free multiple access data MAC, QoS for voice, modem/fax relay, dynamic channel allocation, and advanced bandwidth shaping.

Moreover, symmetry's design allows it to realize the full potential of this advanced technology by including the vast majority of IP in software (including the airlink physical layer using digital signal processing technology), and by featuring a sophisticated suite of network management system tools that allow for complete visibility into the performance of the products. The ability to measure real world performance, to innovate, and to rapidly incorporate these innovations in software has led to the unprecedented airlink performance of the symmetry solution.

SR Telecom's OFDM technology has been successfully deployed by ILECs and large CLECs in Europe, Africa, the Middle East, Asia Pacific, North America, and South America.
