        The path loss in wireless communications is influenced by frequency, distance, geographical features, antenna height of transmitting station and the receiving station and artificial environment. The received signal measurement in wireless environment and the path loss prediction model are widely used, because the RF environment is different from region to region and the frequency band is also wide. There is too much cases using RF field measurement to derive the RF model that is costly and time-consuming. Also, theoretical predict models to derive the RF Model and actual frequency environments is often differ. Thus, both the field measurement and the theoretical prediction models are complementary each other. In this paper, we derived the optimal RF model for mountainous region using actual measured data and variety RF model of coverage simulation results. Also we analyzed the correlation of the field measured data with simulation data.
