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



World's Fastest Commercially Available Wireless Chipset Validated in
Independent Testing

Carlsbad, Calif. - December 13, 2007 - Pulse~LINK, Inc., a pioneer of
Ultra Wideband (UWB) communications, announced today that its recently
released CWave(r) UWB chipset has been validated in independent testing
to have the world's highest data rate available for wireless networking.
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

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

"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

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.
