摘　　要：多网融合室内分布系统主要利用POI多频合路器将多个系统统一接入室内分布系统,对大型室内环境进行覆盖。本文介绍了室内分布系统原理,分析了室内分布系统频率使用情况,研究了各系统在自由空间中的传播性能和封闭室内环境中的覆盖性能,最后根据各系统室内边缘场强,利用室内衰减因子传播模型对各系统同覆盖天线口功率进行了规划分析、提出了两种功率匹配方案,为多网融合室内覆盖设计提供了指导。The multi- network integration indoor distribution system mainly makes use of the multiple frequency combiner（POI） will multiple systems unified access indoor distribution system, to cover the large indoor environments.This paper introduced the principle of indoor distribution system, frequency usage,and study the transmission performance of each system in free space and coverage performance in closed indoor environment.In the end,according to the indoor cell- edge of each system, using the indoor propagation attenuation factor model analyses the antenna power of each system when cover the same distance,put forward two kinds of power matching schemes, provides guidance for multiple network convergence indoor coverage design.

关 键 词：室内分布系统 共建共享 边缘场强 功率匹配
