The Register's Bill Ray reports that the European Commission has laid down a basic plan of adoption for ultrawideband.

"The agreement lays down some restrictions on device capabilities, including an assumption that most UWB equipment will be for indoor use (walls seriously restrict UWB propagation, and thus reduce potential interference) and will shut down transmissions after 10 seconds without acknowledgement," Ray writes.

Until 2011, the use of 4.2 to 4.8 GHz will be permitted without detect-and-avoid interference mitigation solutions -- though eventually, UWB will be expected to shift to above 6 GHz, according to Ray.
