The results of a multi-ray geometric model for estimating the signal coverage in line-of-sight (LOS) and non-line-of-sight (NLOS) microcellular environments are presented, some empirical propagation models are reviewed, and a simplified mathematical rule for estimating the received power for both LOS and NLOS topographies is suggested. The parameters of the proposed simplified model are: the distance between the base antenna and street intersection, distance between the intersection and mobile antenna, width of the street containing base antenna, and the width of the street containing the mobile antenna. Using this model base-mobile path losses for microcellular environments have been evaluated under diversified conditions and the results have been compared with the more sophisticated multi-ray geometric model, and with some empirical results reported in the literature. The fit is, in general, very good. The proposed model can be used in estimating the coverage for microcellular mobile radio communication systems. The computation time of this model is minimal compared to standard multi-ray models
