Coexistence Studies Between 5G and Fixed Service in the 26GHz Band in Colombia

5G technology goes one step beyond mobile connectivity by allowing far more devices to access the mobile internet at the same time, such as objects, sensors, vehicles, and machines. Considering that the 5G commercial is starting, it will be necessary to evaluate the impact for deploying 5G mobile networks in the millimetre bands, which are one of the new bands. In this paper, the aim is to define the technical operating parameters that guarantee the coexistence and 5G systems deployment with the microwave Fixed Service (FS) in the 26 and 28 GHz bands. The results have been obtained by laboratory measurements using professional and commercial equipment in a controlled environment. In fact, laboratory measures allowed to obtain Protection Ratios (PR), to ensure operation between 5G and FS technologies, from co-channel to adjacent band
