Abstract

This paper presents the results of spectrum occupancy measurements carried out in three locations of Kanto area in Japan. Moreover, the collected data corresponding to DTV broadcasting service is analyzed to evaluate the possibilities of secondary systems operating in TV White Spaces (TVWS) in the framework of FCC regulations and Japanese standards. Appropriate propagation models are considered for analyzing the conditions of operation for both, fixed and portable unlicensed devices.
