Shared use of radio spectrum in the EU: From research projects to standards

This paper addresses the current regulatory framework, main research activities and standardization efforts towards a shared use of radio spectrum in the European Union. A survey of emerging spectrum sharing applications and associated standardization paths is described. Remaining challenges for an effective participation of research projects in Cognitive Radio standards are discussed. A new coordination action funded by the European Commission that aims to boost standardization impact of research projects working on cognitive radio and spectrum sharing aspects is presented.
