WiMedia Alliance monitors global regulatory status for UWB applications
(via Press Release from WiMedia Alliance – August 27, 2008) San Ramon, California – The WiMedia Alliance today announced the adoption of the Spectrum Extension Release (SER) update to its UWB Radio specifications. This extension to the existing specifications adds optional features to address certain worldwide regulatory requirements which will allow even broader deployment of the WiMedia common radio platform.
“The SER specification is very significant to implementers of WiMedia radios as it defines important features such as three new channels, tone nulling capabilities which can be used to avoid interference with other spectrum users, and it defines a new bandgroup (BG6), which facilitate greater worldwide use,” said Stephen Wood, President of the WiMedia Alliance. “What this means is that an OEM/ODM could offer a SKU which is suitable for use in all regions worldwide that have approved the use of the ultrawideband (UWB) spectrum.”
With the definition of BG6 (which utilizes the existing UWB bands 9, 10 and 11) manufacturers can now implement 3-band hopping radios on a global basis (subject to local regulatory restrictions). In addition, the SER specification also defines three new 2-band hopping channels (TFI2) which allow radios to increase range (compared to single band operation) when only 2 bands are available for use. Furthermore, the specification also defines “tone nulling” capabilities, to avoid interference with other radios that may be sharing a portion of the same band, in accordance with local regulatory requirements for Detect And Avoid capability (DAA).
Worldwide Regulatory Situation
Another consideration for universal adoption of UWB is the local regulatory requirements for spectrum use. The WiMedia Radio is already authorized for use in major regions worldwide such as the USA, Japan, Europe and Korea; however, the allowed portions of the 3.1 – 10.6 GHz spectrum vary by region, and in some cases they may only be used if DAA or other mitigation techniques are employed.
The regulatory situation is dynamic as various regions determine their individual requirements. In order to track the latest regulatory status by region, WiMedia has created an official chart that will be updated continuously as jurisdictions adopt WiMedia UWB.
