Cognitive radio provides a flexible platform that enables the design of systems using the spectrum in radically new ways. How to harness the power the cognition offers, is still an open problem. New schemes for spectrum utilization have to be power efficient, be applicable in a large scale networks, and be able to co-exist with legacy systems. Regulatory rules and conformance test procedures need to be defined to assure the protection of the legacy systems. In order to make the cognitive radio a success story also the market mechanisms and value chains need to be defined. Spectrum trading and dynamic access schemes should encourage efficient usage of the spectrum and collaboration among the stakeholders. This conference provides a venue for researchers to propose new solutions to the technical, regulatory and techno-economical problems related to the cognitive radios.
