A similar class of device to those known in the US as White Space Devices (WSD) is being researched in the UK and probably many other countries. Whilst the WSD situation in the US is being closely watched by interested parties in the UK and elsewhere, early in 2009 Ofcom launched research and a public consultation on Cognitive Access to the UHF interleaved spectrum.[32] The outcome of this consultation and the related WSD activities in the US could have far reaching implications for users of UHF radio microphones in the UK and around the world.
