The Multiband OFDM Alliance likely will win the race to become the technical standard that governs ultrawideband technologies over the direct-sequencing CDMA architecture backed by Motorola, according to a report issued West Technology Research Solutions, a market-research firm headquartered in Mountain View, Calif.

The Multiband ODFM (orthogonal frequency division multiplexing) Alliance should come out on top in the IEEE 802.15.3a working group because “it main proponents have long planned for future integration of UWB into cognitive radio architectures also preferred today by the FCC,” said Kirsten West, a principal of the firm, in a statement.

West added that the Multiband OFDM architecture is capable of integrating multiple radio front ends—something the DS-CDMA architecture can’t do, she said—and is able to support the development of a multi-protocol baseband architecture that enables the “utilization of cognitive radio methodologies.”

The study estimates that annual worldwide shipments of UWB chipsets into the communications segment will exceed 67 million units by 2007.
