Multimode baseband meets new WiMAX spec
The ComMAX CM1125 is the first multimode baseband processor to comply with the newly announced terrestrial OFDMA radio interface for IMT-2000.
The ComMAX CM1125 from Comsys Communication and Signal Processing 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

Mobile WiMAX baseband aids handset navigation
dmedia System Co is using the ComMAX mobile WiMAX baseband processor for its new product line of advanced personal navigation devices.
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.

"At Comsys we share the bold vision of the ITU-R WP 8F in addressing systems beyond 3G", says Ehud Reshef, Product Manager at Comsys.
"A year ago we announced our commitment to addressing the convergence of 3GSM and WiMAX.
While ITU-R has been working on setting out the principles and promoting a spectrum strategy to meet the needs of a rapidly growing wireless market, we have been concentrating on developing the baseband technology to address the same aims, with the development of advanced processors supporting current and future profiles".
"Our roadmap includes devices that will support W-CDMA and 3GPP-LTE with WiMAX, enabling the full range of possibilities for GSM evolution with WiMAX".
The leadership and innovation of Comsys has been recognised with a string of recent industry awards for ComMAX, including "Best Chip Design" at the Best of WiMAX World Awards 2006: "Best WIMAX Product or Service" at the 2007 Wireless Broadband Innovation Awards, and Runner-Up in "Best Chip Design" at the Best of WiMAX World Europe 2007.
The ComMAX CM1125 is a flexible multimode OFDMA baseband processor that enables service continuity between cellular and Mobile WiMAX (IEEE802.16e) 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.
In the past four months Comsys has announced deals with two leading Taiwanese companies that will use its technology in their devices: dmedia is using ComMAX for its new advanced personal navigation devices (PND), and Infomax is using baseband silicon IP from Comsys in its next generation of cellular handset chips.
