It doesn't say in this piece whether this chip uses the COFDM-based approach (WiMedia Alliance) or the CDMA-based approach. My bet is the latter, in part because WiMedia isn't mentioned, in part because the results are vastly different from all the other recent ones. My feeling has always been that the OFDM approaches had to cut power levels too much, to prevent interference, so they couldn't achieve the high bit rates promised by UWB. This is the sort of performance that makes the new 60 MHz schemes seem redundant.

A comprehensive test of UWB products, conducted by octoScope, showed CWave's 1.35 Gbps over-the-air signaling rate delivering 890 Mbps application layer throughput. CWave performance was 15 to 20 times greater than all other wireless UWB products measured in the test, the best of which peaked at around 50 Mbps at close range. A full report on the independent UWB test results was published in this week's EE Times and Wireless Net DesignLine. "Pulse~LINK CWave technology has delivered on the promise of UWB - HD video distribution," stated Fanny Mlinarsky, President of octoScope, in her report. "With over 500 Mbps of wireless and coaxial throughput and a powerful QoS enabled MAC capable of controlled and predictable performance over multiple media in the house, CWave appears to be the clear technical leader in home networking and is well positioned to emerge as the 21st century architecture for full-home multimedia connectivity." Results of wireless range were also impressive in the octoScope testing, which reported: "The CWave throughput held at around 500 Mbps at up to 8 feet of wireless range and over much of the coaxial range. CWave sustained throughput of 115 Mbps up to 40 feet, at which point we ran out of space in the test facility." The CWave chipset also measured sustained TCP/IP throughputs of 500Mbps across 450 feet of coaxial cable. "We can truly say that we currently have the fastest commercially available wireless networking chipset on the planet," states John Santhoff, Pulse~LINK Founder and CTO. "The peak measured application layer throughput of 890Mbps represents an unprecedented breakthrough in wireless communications, not just UWB." Quality of Service (QoS) and High Data Rate performance are necessary for whole-home high definition video distribution. Devices enabled with the CWave(r) UWB chipset allow consumers to access high-bandwidth HD content from entertainment source devices in one room and display it on any HDTV in the house, utilizing the home's existing coax cabling. Pulse~LINK CWave(r) UWB wireless solution reduces the "rat's nest" of connector wires behind entertainment systems, enabling clean installation of wall-mounted flat-panel displays anywhere in the room. The HDMI extender enables longer-range, secure wireless connectivity between the HDTV display and multiple entertainment source devices such as set-top boxes, video game consoles, DVRs, Blu-ray DVD and HD DVD players. Pulse~LINK CWave(r) 802.15.3b MAC was designed from the ground up to support the QoS demands of isochronous streaming of audio, HD video and High Data Rate digital networking across all available PHY transports media within the home. "Architecturally, CWave appears to offer a significant advantage over the status quo of video transport products requiring disparate MACs to support different media," stated Mlinarsky. Pulse~LINK CWave(r) technology was the only UWB device capable of multi-stream HD video transport in the tests and the only device supporting coaxial cabling in addition to wireless. "There are a lot of marketing claims floating around in the pursuit of High Definition multimedia networking, and it is sometimes hard to know what to believe. We welcomed the opportunity to participate in this independent testing as a means of validating the credibility of our technology," states Bruce Watkins, Pulse~LINK President/COO and co-founding partner. "And, just as the entire UWB industry is at a starting point and continuing to improve, our performance will definitely improve. We see a relatively straightforward roadmap to doubling performance at such time as market requirements dictate. This is just the beginning for a superior technology that delivers today and can continue to scale with the demands of tomorrow." CWave(r) high-volume commercial chipsets are available now and the company is introducing reference design kits for its CWave(r) UWB Wireless HDMI, HDMI-Over-Coax, Ethernet-Over-Coax and 1394-Over-Coax solutions. The RDKs are low cost, small form factor, production ready reference designs, enabling OEM customers quick market entry. All four "flavors" of the CWave(r) HD home networking technology will be showcased at the 2008 International Consumer Electronics Show (CES) in Las Vegas, Nevada, January 7-10, in the Pulse~LINK booth (South Hall 2- #25559) and various partner locations throughout the show floor. The UWB performance test was coordinated by industry expert Fanny Mlinarsky, a highly-regarded consultant with more than 24 years of senior R&D expertise in wireless technologies. Mlinarsky is president of octoScope, a Boston area consultancy. She is also the founder of Azimuth Systems, a test equipment company specializing in wireless technologies. In August, she published a three-part analysis of IEEE 802.11n systems: Testing Draft IEEE 802.11n systems: Not all "n" is created equal.
