Existing and near future work in CEPT on cognitive radio solutions

This paper informs about the existing and near future work in the CEPT, i.e. 48 European National regulatory authorities, responsible for spectrum management in Europe on cognitive radio (CR) solutions; in particular on the work on regulatory approaches for wireless applications under general authorization regime (i.e. commonly called license exempt); Cognitive techniques need to be analyzed not only from the perspective of the technical feasibility but also from the perspectives of the demand, fit to application and investment requirements, the level of technical complexity involved, and the long term predictability of the spectrum access.
