摘　　要：5G频段高且传输和穿透损耗大,室内覆盖需求和建设难度相比4G均大幅提升,如何充分利旧现有资源、低成本快速实现5G室内覆盖是运营商亟需解决的重要问题。探讨一种通过利旧现网馈线、新增合路器、改造楼层主干等手段实现错层双流的5G室内覆盖方式,为5G室内分布系统建设提供参考。The 5G frequency band is high,the transmission and penetration losses are large,and the indoor coverage demand and construction difficulty are greatly improved compared with 4G.How to make full use of the existing resources and quickly realize 5G indoor coverage at low cost is an important problem that operators need to solve urgently.This paper discusses a 5G indoor coverage mode of staggered double-flow by using existing feeder,adding combiner,and reforming floor trunk,which provides a reference for the construction of 5G indoor distribution system.
