To meet the large and rapidly increasing demand of radio resources in the world, a new spectrum utilization policy that can maximize the efficiency of frequency utilization and can accommodate more wireless services is under consideration. Recently, the increase of the efficient use of radio resources based on cognitive radio technology is studied. In the United States, the frequency re-allocation in the VHF/UHF band is carried out along with the switchover from analogue to digital TV. It is expected that the application of cognitive radio technology for this band would provide more efficient and effective use and would have significant benefits for the public by allowing the development of new and innovative types of unlicensed radio devices. This paper describes the trends of the radio regulatory policy and the technical standard for the operation of unlicensed devices on the TV band in the U.S.
