摘　　要：介绍了PHS、3G和WLAN三个无线业务使用同一套室内分布系统实现3种信号同时覆盖;首先讨论了这三个业务各自的室内覆盖系统及其具体设计参数等;然后介绍了共用系统中有源设备的合路情况;分析了共用系统中存在的功率匹配问题,得到了相关结论。对各工作频带间的相互干扰问题做出了相关分析并给出了部分解决方案。The same indoor distribution system （IDS） is used in the three wireless operations PHS,3G,WLAN to realize all the three signals being overlaid simultaneously in this paper. Firstly,IDS and design parameters of each operation are discussed. Then, multiplexing of active equipment in community system is introduced. By analysing power matching in community system, it achives a conclusion. Mutual interference between channels is analyzed and some solutions are proposed.
