Análise da Coexistência entre Sistemas 5G e Serviços Fixos na Faixa de Ondas Milimétricas

Abstract

This works aims to analyze the impact of interference of a 5G system over a legacy 26 GHz fixed point-to-point system and, thus, obtain a minimum protection distance for the fixed system not be affected by the 5G system. To obtain these results, simulations were performed using the Monte Carlo method. The impact of 5G network co-channel interference on the fixed service was evaluated considering different parameters such as fixed antenna height, cell number, fixed antenna gain and number of users. In the results obtained, the 7-cell tri-sectored network topology, combined with a 60 m of fixed antenna height, had the greatest impact on the required protection distance, while other parameters such as gain and power had a moderate impact. These results imply that coexistence will be possible when all appropriate parameters are measured for each case in question. Another contribution of this dissertation is the availability of a coexistence model in the SEAMCAT simulator, which can help new scenarios for coexistence analysis.
