Smulders The worldwide opening of a massive amount of unlicensed spectra around 60 GHz has triggered great interest in developing affordable 60-GHz radios. This interest has been catalyzed by recent advance of 60-GHz front-end technologies. This paper briefly reports recent work in the 60-GHz radio. Aspects addressed in this paper include global regulatory and standardization justification of using the 60-GHz bands 60-GHz consumer electronics applications radio system concept 60-GHz propagation and antennas and key issues in system design. Some new simulation results are also given. Potentials and problems are explained in detail. Copyright 2007 Nan Guo et al.
