In recent years, with the advent of the 5G era, the influence of UAVs Unmanned aerial vehicle is expanding and the civilian UAV market is showing a blowout. Because UAVs are lightweight, flexible and can be used in extreme environments, there are nearly 100 applications in the civilian sector. For areas with poor infrastructure, UAVs can carry base stations to undertake communication tasks. At the same time, collisions between UAVs and interference from ground users have emerged. In this paper, the parameters of international mobile telecommunications (IMT) system UAV-mounted base stations and 1800MHz broadband time division dual (TDD) private network system are introduced. Then, deterministic calculation method is used to study the situation of UAV interference with neighboring frequency broadband TDD private network system, and believe that 1800MHz UAV-mounted base station can realize coexistence with neighboring frequency broadband TDD private network system. When the interference isolation distance between UAV and other systems is up to 0.1km, which is less than the flight altitude of UAV of 4km, no additional isolation distance is needed to achieve coexistence.
