Simulation Model of 5G Coverage in Urban Areas

The introduction of 5G offers prospects for the development of various economic sectors due to many advantages of this technology. In connection with the active introduction of new communication and broadcasting systems, adequate modeling of radio wave propagation in urban environment becomes an urgent problem. Thus when frequency-territorial planning of the 5G system, it would be useful to calculate the signal behavior for a given frequency in the current conditions. In this paper, using the algorithm of three-dimensional ray tracing, the effects of multipath signal propagation under conditions of high-rise urban environment are simulated. The simulation of 5G system coverage in urban conditions is performed at two frequency bands (3.4-3.8 GHz and 24.25-29.5 GHz), taking two values of the transmitted signal frequency - 3.5 GHz in one case and 26 GHz in the other. The application of the proposed model during preliminary frequency-territorial planning of the system allows choosing the optimal location of the transmitter to ensure the maximum coverage area in the selected place. In addition, when given the location of the transmitter and the buildings, it allows selecting the best installation locations orientation of external subscriber antennas.
