摘要
城市轨道交通作为无线通信的"盲区"有着人流量大、移动性强、地形狭长、信号入射角度小、隧道信号不均匀等特点。为轨道交通量身定做一个符合其特点的信号覆盖系统,既满足了客户对优质通信环境的需求又具有良好的社会和经济效益。文章首先简要介绍多系统合路平台(POI)的工作原理,在此基础上从组网方式、分布式系统的设计等方面总结轨道交通信号覆盖设计的一些思路。
Urban rail transit as a ＂blind area＂ of wireless communication the characteristics of the stream, strong mobility, long and narrow terrain, small angle of the incoming signal, uneven signal of the tunnel,etc. Research and design wireless networks and mobile communications for Urban rail transit can improve the quality of communications networks,to meet customers＇ quality communications needs of the environment, it also increased the traffic and operating profit, which has a good social and economic benefits.This-paper briefly introduces the working principle of POI, on this basis, from the network mode, and the design of the distributed system to summarize some ideas of design for rail transit indoor coverage.
