Due to increased demand for wireless communications, e.g. cellular, wireless LAN and broadband wireless access, radio frequency spectrum is becoming more and more precious resource. Cognitive radio is one of the promising technologies to further improve spectrum efficiency. Due to the nature of the technology, it has many facets, including its enabling technologies and system architecture, its implementation issues and its operational/regulatory implications. Different fora and organizations are currently working on the standardization of cognitive radio from these different facets. This special session introduces and discusses the ongoing standardization activities on cognitive radio systems on a global or regional basis.
