Predição de cobertura de radiofrequência (RF) para o sistema de telefonia móvel celular 5g com ondas milimétricas

Abstract

The telecommunication area is constantly evolving, always looking for new forms of communication, preferably with faster data rates and low latencies. Through this, the emergence of 5G promises to bring these characteristics with the use of millimeter waves with high frequencies. In this way, the work developed aims to make the coverage prediction for the radio frequency mobile phone system in the São Luís region, applying the concepts of millimeter waves with the use of the free tool Radio Mobile that uses the propagation model of LongleyRice. In this way, a comparison of downlink and uplink was made between two communication networks, 3,5 GHz, and the other 26 GHz. With results of percentage coverage area in the downlink of 93.72 % and 91.6 % and uplink of 90.5 % and 90.49 % on the frequencies mentioned, respectively. Even a balanced link Budget in the networks, there was a divergence between the downlink and uplink, since different ERB numbers were needed to cover more than 90 % of the covered area of the studied region. Therefore, it was successful to achieve the objectives shown in the work, despite the difficulties with the interferences and the low range that millimeter waves can offer
