摘　　要：随着5G技术的发展,地铁中公网通信也需要考虑5G覆盖,地铁公网通信是采用泄漏电缆来实现的,相应的泄漏电缆数量也要是4根。本文对三大运营商进入地铁的十几个系统进行了互调干扰分析,给出了各系统在4根漏缆中分配的建议。With the development of communication technique,5G network needs to be considered in the public radio network coveraged the metro.In order to use the advanced technology of 5G network,the public radio network needs to use 4 leaky cables to coverage the metro tunnel.All three telecom operators have more than ten network systems,about the allocation of network systems in the 4 leaky cables,this paper analyzed the intermodulation interference in the more than ten network systems and gived some suggestion.
