Abstract： In the third year of 5G construction in 2021,the focus will be on the scale deployment of 5G indoor distribution system.The characteristics of low cost and low failure rate of passive indoor subsystem conform to the national construction and sharing strategy.Intersystem modulation interference has become an urgent problem to be solved in the construction of multi-system integration.Based on the in-depth analysis of the principle of IMI, this paper studied the possible IMI of 5G cell subband, proposed the solution of IMI of 5G cell subsystem, and combined with the case of a cell submodulation interference of Tower Company, put forward suggestions on how to solve the problem of IMI.
Key words : 5G,；multi-system,；indoor distribution system；interference
