The Motivation
Article 44 of the ITU Constitution: “Member States shall bear in mind that radio frequencies and any associated orbits… are limited natural resources and that they must be used rationally, efficiently and economically, in conformity with the provisions of the Radio Regulations…”
Article 45 of the ITU Constitution:“All stations…must be established and operated in such a manner as not to cause harmful interference to the radio services or communications of other Member States…”

Candidate band Potential sharing band Allocation in ITU Region 1
24.25-27.5 GHz 24.65-25.25 GHz FSS (E-s)
37.5-40.5 GHz 37.5-40.5 GHz FSS (s-E)

FSS ES parameters: Antenna Gain: 34 dBiCarrier BW: 1 MHz
IMT vs FSS : C-BAND SHARING SCENARIO
5G station is to be located at 1-12 km away from a satellite ES to meet the criteria for compatibility

Summary
The drivers of efficient use of spectrum/orbit originate both from regulation and industry technology trends
The use of appropriate radio engineering tools is mandatory for radio services’ coexistence studies and consequent informed decisions on the regulations of radiocommunications.
