Abstract—New innovative technology such as unlicensed wireless connectivity has become essential to provide more beneficial and advanced services. Therefore, it is necessary to study the use of broadband available and potentials of spectrum harmonization for massive unlicensed applications, equally Wireless Fidelity (Wi-Fi) with higher frequency and wider bandwidth. This paper presents an interference assessment between unlicensed Wi-Fi service and an incumbent service such as Outside Broadcasting (OB) system in the 6 GHz band. It also includes several radio interference scenarios to analyse coexistence by Minimum Coupling Loss (MCL) and Monte Carlo (MC) methods. Consequently, this study suggests protection distance as a possible approach for the coexistence of the unlicensed Wi-Fi service and OB system in the 6 GHz band.
