60 GHz radio channel propagation characteristics in indoor office environment are addressed in this paper using full 3-Dimensional ray tracing of Wireless InSite and a simple deterministic 2-Dimensional model utilizing Ray-tracing technique. The comparisons are made with free space model and site-general prediction model of ITU-R. Values of the path gain, rms delay spread for sectoral horn and omni-directional antennas are presented. Also, path loss exponent and channel capacity values deduced from the simulation investigations. © 2012 IEEE.
