A Comparative Study of Wireless Propagation Simulation Methodologies: Ray Tracing, FDTD, and Event Based TLM
نویسندگان
چکیده
This paper compares ray tracing, finite difference time domain, and the event driven transmission line matrix models as tools for making site specific pathloss predictions in cluttered environments. A brief overview of each type of model is presented. The accuracy and computational cost of a ray tracing, FDTD, and event based TLM model are compared for a small, indoor propagation experiment. The potential for producing accurate, site specific path-loss databases using the fast event based TLM model is discussed in the conclusion.
