Propagation Characterization Based on Ray-Tracing at 60 GHz Band: A Typical Indoor Office Scenario and Validation Measurements

In this paper, we present modeling and analysis of channel characterization for a typical indoor office environment at 60 GHz based on the ray-tracing method. We provide by means of Wireless InSite™ software a very detailed three-dimensional (3-D) environment model considering appropriate electromagnetic parameters of the material, which based on the ray-tracing technique allows an adequate approximation of the examined indoor scenario. The simulation results include the over-the-air (OTA) and a comparison with the channel measurement through the 60 GHz Fujikura communications commercial equipment has been performed, where a good agreement has been obtained. The received power, delay spread, and coherence bandwidth are plotted to illustrate the impact on the received wireless signal at each receiving point due to the obstruction of the surveyed environment. In addition, the obtained results have allowed us to reach a better knowledge of the 60 GHz propagation channel in an indoor office scenario and consequently about the 802.11ad standard.
