Abstract: 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.
 

Special session 2: Strategical National and Regional R&D Projects Regarding Efficient Spectrum Management for Future Wireless Network

Abstract: We have recently encountered a serious lack of frequency spectrum resources with rapid deployment and worldwide expansion of wireless communication systems such as cellular phones. Under such circumstances, in order to ensure the spectrum resources for vital mobile communications, advanced technical research and development (R&D) is necessary to enable effective and efficient management of restricted spectrum resources. The cognitive radio system and heterogeneous radio system have recently attracted attention for efficient usage of frequency resources. Furthermore, the TV White Space has been also drastically discussed for the spectrum sharing among different wireless systems. For such objectives, many strategic national and regional R&D projects have been organized. Under these projects, many R&D organizations and universities are conducting R&D activities. In the proposed special session, it is required that the outline, objective and obtained results of the strategical projects are introduced. By exchanging the opinions among the researcher engaging in the forward-edged wireless technology, their R&D activities are expected to be accelerated.
