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.
