漏泄通信系统在地铁中的应用

地铁内信号的覆盖问题始终困扰运营商,目前行之有效的方法是搭建一套漏泄通信系统.此系统首先应用合路平台设备(POI)技术;其次采用漏缆传输方式对地下空间进行信号覆盖;再次通过有线方式将各运营商的信号传送到地铁站内的各自基站,系统信号经POI合路后通过地铁内的漏缆把信号发送出去,从而实现地铁内信号的覆盖.最后将研究成果应用到某运营商地铁线路的网络建设中,为后期地铁无线网络设计提供了思路.

Application of leakage communication system in Metro

The subway signal coverage problem has always been the operator, currently is an effective method to build a Leaky Communication system. The system first application platform equipment (POI); followed by leakage cable transmission mode of underground space signal coverage; again through the wired way will the operators of the signals are transmitted to the subway station of each base station, signal system after the POI by underground leaky cable to signal is sent out, in order to achieve coverage of the subway signal; finally, the research results are applied to the network construction of a subway line operator, late subway wireless network design provides a train of thought.
