Predicting propagation characteristics using the ray-tracing method requires detailed landform data, structure data, and a high-level workstation that can quickly calculate a heavy load of ray-tracing calculations. Therefore, it is very difficult for each user to build such a system. In this paper, we present the construction and performance of a ray-tracing system called 3D-PRISM that any user can easily use at anytime and anywhere.
