Abstract

This work presents a study of coexistence between IMT 2020 systems (5th Generation mobile systems - 5G), using beamforming and sector antennas, and domestic satellite television reception stations (TVRO) in the C Band. It is proven that the greater directivity of beam-forming antennas used in IMT 2020 systems, combined with the use of filters with rejection of at least 30 dB or the use of modern TVRO receivers, with saturation thresholds above -30 dBm makes coexistence between IMT 2020 and TVRO systems possible, due to the low probability of harmful interference.These results are extremely important, given the imminent deployment of 5G mobile networks and the number of TVRO receptors, which could have their operations impacted by the new systems in operation in Brazil.
