Wisair Demonstrates Ultrawideband Detect and Avoid Technology at European Regulatory Meeting
Illustrates Feasibility of UWB and Broadband Networks Coexistence
Tel Aviv, Israel – September 22, 2005 – Ultra Wideband (UWB) and Wireless USB solutions provider Wisair demonstrated “detect and avoid” technology at a CEPT Electronic Communications Committee meeting (ECC TG3) held in Copenhagen. The demonstration aimed to assist European and Japanese regulators in defining conditions and measures for UWB radio spectrum usage, while protecting other radio services such as WiMAX or 3G/4G cellular networks from excess interferences.
Last month, Japan's Ministry of Internal Affairs and Communications (MIC) made an initial regulatory proposal for a UWB emission policy, requiring “detect and avoid” techniques for the 3.4- to 4.8-GHz band. These techniques can mitigate interference by searching for broadband wireless signals and then automatically switching the UWB device to another frequency to prevent any conflict.
The Wisair demo consists of two UWB devices communicating through a UWB link on a specific band. Once a broadband signal is detected the UWB devices automatically switch to a free band to avoid interference.
“UWB can coexist effectively with both current and future wireless technologies sharing the same spectrum” said Gadi Shor, Chief Technology Officer at Wisair. “Designed properly, detect and avoid provides the flexibility to support regulatory measures in different areas of the world and ease concerns about interference.”
Wisair’s “detect and avoid” technology will also be demonstrated at the Wisair Japanese office.
