European regulatory developments related to CR

Abstract

This section will review the European regulatory developments pertinent to CR. However it must be clarified from the beginning that the current state of thinking in European regulatory circles does not really consider the CR as the subject of regulatory policy, but rather as pure technological innovation phenomenon that should find its way to fit into the existing regulatory service definitions and spectrum access rules. Moreover, the CR term is generally understood in current European (and elsewhere) regulatory context as a moniker for DSA-enabling solution, and in that sense the White Space Devices (WSD), as may be deployed in the traditional TV Bands, are seen as proxy CR systems to be encountered in the near future. Thus in the rest of this section the terms WSD and CR are used interchangeably and should be seen as being synonymous.
