The increasing amount of data and video traffic carried by mobile networks has recently risen the demand for enhanced network capacity, more efficient use and more effective management of spectrum. Cognitive radio technologies candidate to respond to these urgent needs by allowing a near simultaneous band sharing. The regulation plays a crucial role in promoting the adoption of these technologies, in order to overcome the traditional paradigms of authorizations for exclusive spectrum usage. The article outlines spectrum management regimes where the implementation of frequency sharing technologies, including cognitive technologies, is foreseeable and brings them back to a comprehensive taxonomy of dynamic spectrum access and sharing models, in the effort to reconcile partially diverging approaches and nomenclatures suggested in literature. Theoretic analysis is supported by a number of illustrations and practical experiments with shared spectrum usage. Based on suggested taxonomy, the research aims at showing the evolutionary path toward the introduction and spreading of cognitive and other spectrum sharing technologies, pointing out relevant trends and instruments made available by the reform of EU Telecom Package, as well as at outlining the status of regulation, policy and standardization in Europe.
