Pulse~LINK Introduces Solution for Guaranteeing Co-existence of Multiple UWB PHY Layers at IEEE Meeting

SAN DIEGO, Calif.- September 25, 2003 - Pulse~LINK, Inc. announced at the IEEE Standards meeting in Singapore last week its submission of a proposal for a "Common Signaling Protocol" designed to facilitate co-existence between multiple devices utilizing different Ultra Wideband Physical Layers. Along with its proposal for a Common Signaling Protocol, Pulse~LINK has offered to contribute to the standards process Intellectual Property that would enable the core protocols. The solution will equally benefit all UWB manufacturers and developers and insure a path for co-existence between dissimilar UWB Physical Layers.

The issue of Ultra Wideband co-existence has traditionally centered on narrowband communications. Pulse~LINK's proposal looks further down the road at the issue of co-existence of UWB devices from differing manufacturers utilizing dissimilar UWB PHY Layers. While the IEEE 802.15.3(a) working group is presently focusing on a common standard for UWB Wireless Personal Area Networks (WPAN), there are companies proposing the use of UWB for both IEEE 802.15.4 and 802.11n along with a host of yet to be announced interfaces and applications.

The implementation of a UWB Common Signaling Protocol as proposed by Pulse~LINK, will insure reliable, robust performance of UWB devices sharing dissimilar PHY Layer interfaces. This feature will become particularly important once UWB achieves wide spread penetration into the marketplace and devices are used with incompatible UWB air interfaces in close proximity to each other. A similar example already exists with narrowband communications in the unlicensed ISM 2.4Ghz band, where interference between WiFi, Cordless Phones, Bluetooth, Microwave Ovens, etc., often render many of these devices inoperable when in the presence of each other.

Pulse~LINK's Common Signaling Protocol proposal entails a methodology for allowing multiple different UWB PHY Layers to co-exist in the same coverage area through cooperative management of the PHY Layer Air Interface. Pulse~LINK's proposal defines a simple architecture that could be inexpensively enabled on any UWB device, and openly contributes a foundation of Intellectual Property to do so.

"We have a once-in-a lifetime opportunity to define an emerging wireless standard on a potentially global scale", states Pulse~LINK founder and CTO, John Santhoff. "We believe it is important to use this opportunity to address co-existence and interoperability of differing UWB Physical Layer Air Interfaces as a part of the standards process rather than as an after thought. Addressing UWB interoperability issues on the front end of the standards process will allow UWB to side step many of the problems that have plagued users of un-licensed spectrum in the past."
