摘要: Cognitive radio is being intensively researched as the enabling technology for license-exempt access to so-called TV White Spaces (TVWS), large portions of spectrum in UHF/VHF bands which become available on a geographical basis after digital switchover. Both US, and more recently, UK regulators have given conditional endorsement this new mode access. This paper reviews state-of-the-art technology, regulation, standardisation cognitive TVWS. It examines opportunity commercial use cases associated with form secondary
