Ofcom is considering freeing ultrawideband (UWB) spectrum from all licensing restrictions, the regulatory body announced yesterday.

Outlining new proposals for what to do with UWB, it said it was consulting with the public on proposals as part of a harmonised European approach to the technology. In April, the European Commission will consider initial proposals on the EU's approach to UWB..

UWB technology transmits radio signals simultaneously over a wide range of frequencies and can be used in a variety of manners, including high-speed, short-range wireless communication, like WLANs and for radar imaging of objects underground or behind walls.

Ofcom said that although it is proposing that UWB be freed from licence restrictions, any measure it approves would have to avoid harmful interference, particularly to services such as 3G mobile, wireless broadband and radio astronomy. The consultation ends 25 March.
