Academic Study of Feasibility Coexistence Between 5G Candidate Bands and Existing Service in Indonesia

Based on the timeline of the International Telecommunication Union (ITU), 5G technology will be officially held commercially in 2020. Several leading market countries have begun conducting trials and preparations to deploy their 5G networks in accordance with the timeline of ITU. Indonesia as a country with a large growth of internet and mobile phone users must begin to accelerate the steps to deploy 5G networks in Indonesia. One of the acceleration steps taken is to study the feasibility of 5G candidate bands in Indonesia and the possibility of sharing spectrum scenarios with existing services. From the simulation results it was found that the low band sharing spectrum between 5G with analog TV on the 700 MHz band could not be done because it requires a protection distance of 20 Km. In the middle band 3.5 GHz sharing spectrum between 5G BS and ES FSS requires a protection distance of 10 Km for the elevation angle of the ES 20° antenna. And in the high band 28 GHz sharing spectrum can occur between 5G AP with FSS without protection distance for the elevation angle of the ES antenna 20° and a protection distance of 5 Km for the antenna elevation angle ES 0° and 10°.
