Abstract： In order to determine the feasibility of additional allocations to the mobile services on a primary basis in the frequency band 31.8～33.4 GHz, this paper analyzes the electromagnetic compatibility between the 5th Generation(5G) international mobile telecommunications system and radionavigation service, which is the principal services according to regulations on the radio frequency allocation in the frequency band. The paper simulates the aggregated interference from the 5G base stations, adopts the latest parameters and the typical characteristics of radionavigation service, and calculates the interference probability in different scenarios. The simulation results show that the 5G base stations may cause harmful interference to radionavigation service, so it is not recommended to introduce mobile communication system in this frequency band.
Key words : 5G system；radionavigation service,；co-existence analysis
