Propagation Loss Model for Mobile Wireless Communication Systems

In this paper the model of propagation losses is proposed. It is based on the measurement of the received power as a function of distance and antenna height. The pattern of propagation losses is determined by Linear Regression using a two-dimensional one degree polynomial model. Additional statistical analysis of measured data was used to separate them into two cases of propagation - NLOS and LOS - in an urban environment. This approach is useful because it does not limit the measurement route and the accuracy of the model can be increased if the measurements are done only in the area where the wireless system will operate. The application of the proposed model in the calculation of the coverage radius through the radio communication budget is presented. The discussed models can be used in the design of the coverage of mobile wireless communication systems implementing Zigbee, IoT and other technologies.
