Abstract

In this paper, we have investigated the impact of rainfall of different intensities on cellular systems with millimeter waves in concrete environments. The data of specific areas are map-based, obtained from openstreetmap.org, and consist of variable degrees of urban and infrastructural developments. In this case, the results of losses in the propagation of millimeter waves, obtained by the ray-tracing imaging method, are compared with those given by Recommendation ITU-R P.838. The results show significant differences, with increased losses in the map-based channel model scenario concerning the data provided by the relevant recommendation. The increased distance between the transmitter and the receivers showed even more significant differences in the results of the simulated scenarios compared to the ITU-R P.838. The paper presents the research results on the frequency 28 and 38 GHz, but comparable results were for other frequencies of millimeter waves, like 68 and 73 GHz.
