Abstract: Models of radio channel propagation are indispensable in the analysis and design of wireless communication systems. They are used to predict power and interference levels and analyze other properties of the radio link. The main goal of this work is to present a tool that we have developed subject to characterize and modelling indoor radio channel propagation. The tool is based on the ray tracing technique (RTT). This, is used to predict the propagation of HF electromagnetic waves. As, in realistic environment we cannot neglect the significant impact of Human Body Shadowing and other objects in motion on indoor 60 GHz propagation channel. Hence, our proposed model allows a simulation of propagation in a dynamic indoor environment. First, we describe a model of human body. Second, RTT with this model is used to simulate the propagation of millimeter waves in the presence of persons in motion. Results of the simulation show that this tool gives results in agreement wi!
th those reported in the literature. Specially, the effects of people motion on temporal channel properties. Other features of this approach also are outlined.
