Path loss prediction model for a sloped area in microcell based on scale model and real environment measurements

We propose a model for predicting the path loss of a sloped area in a microcell service area of a mobile communication system. This is the prediction model to be proposed that targets a microcell. For practical use, a model requires parameters such as the base station height, angle of the sloped area, and distance from the base station to the sloped area. The proposed model uses a correction method based on the characteristics of the base station height to predict the path loss of the sloped area based on the path loss of flat terrain. The proposed model is verified based on measurements of a scale model and real environments. A 1/70 scale model is constructed of a residential area and the path losses are measured at 10.5 GHz. In real environments, the path losses are measured at 902 MHz. The measurement results show that the path losses predicted using the proposed model are close to the measured results.
