Model Prediction of Radio Wave Propagation Loss at Microcell in Mobile Communications

Based on the radio wave propagation loss model in free space and the characteristics of radio wave propagation in microcell,this paper proposes the generalized predicting model of radio wave propagation loss,whose key points are to use the minimum inflection point distance to reflect unitedly the influences of antenna height and system frequency and the path attenuation exponential is used to reflect the varying surroundings in the radio wave propagation path.
