A Modeling for Radiowave Propagation of M/W bands in Microcells

Abstract

The propagation models can be classified either empirical or deterministic, otherwise a combination of them. In this work, the developed model for 8 GHz band in microcell is the combination of empirical and deterministic method. The model requires the environment database in terms of the distribution rate of buildings. In LOS, the received power mainly depends on direct wave, ground-reflect wave and building-reflect wave due to both side of the road. The direct and ground-reflect wave come from deterministic method and the building-reflect wave derives from empirical method. The developed model overcomes the complexity of an explicit mathematical expression and the accuracy limitations by the measurement method
