地铁公网泄漏电缆间隔离距离探讨

Thinking of isolation distance about the leaky cable of metro public radio network

地铁隧道内公用无线通信网络使用泄漏电缆进行无线覆盖,一般都是采用上行和下行各用一条泄漏电缆。在隧道的有限空间内两根泄漏电缆的间隔距离应该多大,从干扰需求、MIMO技术需求以及安装空间大小3个方面进行了论述,最终得出了建议的间隔距离。

The public radio network coveraged the metro tunnel using the leaky cable, and in general the uplink and downlink had the respective leaky cable. About the isolation distance between the uplink leaky cable and the downlink leaky cable, this paper discussed the question from three aspects, the interference factors, the MIMO technology demand and the installation space, and by analyzing these factors, proposed an isolation distance.
