摘要：目前，LTE-M系统在城市轨道交通的应用非常广泛，系统可用于承载列车运行控制业务、列车紧急文本下发业务、列车运行状态监测业务、车载视频监控业务、PIS视频业务和集群调度业务，因此，为满足高可靠性、全网无单点故障的要求，LTE-M系统须在覆盖方案中采取冗余措施。本文结合工程应用的实际经验，从漏缆共享、无线信号合路及无线覆盖场景等因素入手，对LTE-M系统冗余覆盖方案的应用进行分析与研究，以期为系统设计提供参考。

Abstract：At prent， the application of LTE-M system in urban rail transit is very extensive. The system can be ud to carry train operation control rvices， train emergency text delivery rvices骑行， train operation status monitoring rvices， vehicle video surveillance rvices， PIS video rvices， and trunked dispatching rvices. Therefore连锁店加盟排名， to meet requirements of high reliability， no single points of Failure in the entire network， The system must take redundancy measures in the coverage scheme. This paper starts with factors such as leaky cable sharing， wireless signal combining and wireless coverage scenarios早点回家， and analyzes the application of redundant coverage scheme for LTE-M system. Rearch to provide a reference for system design.
