Comsys Communication and Signal Processing, a leader in wireless baseband solutions, has announced that its ComMAX CM1125 is the first multimode baseband processor to comply with the newly announced terrestrial OFDMA radio interface for IMT-2000.

The recent meeting in Kyoto, Japan of the ITU Radio communication Sector (ITU-R) Working Party 8F (WP 8F), which concluded with the forwarding of key recommendations and reports for the expansion of the IMT-2000 radio interface standard to include OFDMA technology, has brought WiMAX under the umbrella of this new extensive standard.

The Comsys CM1125 is the first IMT-2000 baseband to support the WiMAX TDD profile, and Comsys is the only company that has currently announced it is working on multimode GSM/EDGE/WiMAX baseband processors for mobile phones and terminals.

The new interface, OFDMA TDD WMAN, is a specific subset of WiMAX that complements the existing family of IMT-2000 radio interfaces. The WP 8F proposals update and expand the family of IMT-2000 radio interfaces, establishing a foundation for a ‘beyond 3G’ standard named IMT-Advanced, and at the same time call for the provision of additional spectrum for IMT, with the aim of securing a forward path beyond 3G that balances the market and services expectations with the constraints of technology and available spectrum.

The ComMAX CM1125 is a flexible, multimode OFDMA baseband processor that enables service continuity between cellular and Mobile WiMAX (IEEE 802.16e) networks. ComMAX provides manufacturers of multimode mobile WiMAX terminals with a comprehensive and flexible broadband solution fully compliant with WiMAX Forum Wave 2 requirements, offering MIMO capability, which can operate over multiple bands. Featuring service continuity support between Mobile WiMAX and legacy GSM/EDGE networks, ComMAX provides best-in-class performance and offers substantial cost and power savings.
