Pulse-Link IC suits UWB SDCR solution 

17 May 2004

    Ultra Wideband (UWB) chipset developer Pulse-Link Inc. has disclosed that it has developed the first IC for a media-diverse UWB Software Defined Cognitive Radio (SDCR) solution.

    The target data rates for the chipset, planned for commercial release mid-2005, are up to 1Gb for UWB wireless connectivity, up to 200Mbps for UWB power line communications (electrical wiring in homes and small offices), and up to 1Gb of new downstream bandwidth across existing cable television networks in addition to hundreds of megabits of new bandwidth per node upstream.

    According to Pulse-Link, the SDCR approach provides a single solution for total home networking with wireless LAN capabilities that can be further enhanced through home electric power lines and cable technologies. Because the chipset automatically selects which networking solution to use, the consumer need not be concerned whether the networking is done over wires or wirelessly.

    "The fundamental architecture of our integrated circuit, implemented on Jazz Semiconductor's SiGe 120 process, is that of a Software Defined Cognitive Radio," said CTO John Santhoff. "The hardware platform we have defined represents a significant leap forward in communications. It reduces the complexity and implementation of wireless and wired physical layers to a software abstraction."

    The test silicon unveils an architecture that supports the company's UWB wireless, UWB power line, and UWB cable communications technologies simultaneously on the same chipset.

    "The combination of all three forms of UWB communications on a common platform obviously represents a significant departure from the currently popularized pursuit of UWB as a means to replace USB2.0 cables," according to Bruce Watkins, Pulse-Link President and COO. "That is a good application of UWB with obvious market potential, but it isn't the only application for UWB."
