Based on deeply analyzing the propeties and propagation mechanisms of microcellular mobile radio channel

this paper researches and proposes the new generalized prediction model of radio wave propagation loss in microcellular multipath dispersive channel

whose key points are to characterize the influence of three dimensions multipath dispersive channel performance on radio propagation with the help of additional path attenuation factor

and to use the minimum inflection point distance of the first Fresnel region in propagation channel as a characteristic porameter expressing unitedly the influences of antenna height and frequency. Finally accordingto the prediction model

the radio wave propagation loss performance in different conditions is analytically simulated.
