Sequoia Communications announced at Mobile World Congress that its SEQ7400 HEDGE transceiver has been verified to support HSUPA, TD-SCDMA, S-Band and GMR satellite specifications via extensive testing. Originally introduced in May 2007, the SEQ7400 is based on the company's patented FullSpectratm all-polar architecture.
Sequoia Communications will demonstrate the SEQ7400, operating in all of these modes, in the company's booth (Hall 2, Stand 2F69) at Mobile World Congress in Barcelona, Spain, held February 11-14, 2008.
Sequoia Communications' radio architecture is an alternative to software-defined radio. Sequoia's concept is to use a single radio architecture that supports all modulation types using customized digital circuitry. "Our patented polar architecture is fundamental to enabling the 'flexible radio' concept," said John Groe, CTO and founder of Sequoia Communications. "It uniquely provides the flexibility to process both narrow-band and wide-band modulation schemes using a single radio." The company reports that test results show the SEQ7400 meets cellular specifications for WCDMA and HSDPA, and that it can be extended to a variety of other applications without any modifications to the chip itself.
