This paper presents design procedure about a simulator newly developed for micro cellular system planning, which contains a new propagation analysis algorithm. The algorithm is based on processing of vector data for roads and buildings which mainly affect the propagation phenomena in micro-cell environments. The paper introduces a simplified ray path search technique and it shows a capability of predicting path loss with a comparative accuracy, although it doesn’t use complicated ray-theoretic methods such as a ray tracing technique. Results presented in this paper indicate that the algorithm is capable of predicting path loss with an rms error of 5dB or lower. The proposed propagation analysis algorithm has been developed to aim at the practical application for micro-cell planning such as PCS or CT-2 system.
