对轨交无线通信分布系统设计的探讨

Discussion about Design of Rail Transit Radio Communication Distribution System

轨交无线通信分布系统的合理布局为实现地下区域内无线信号的良好覆盖打下基础。从限定空间下无线电波传播特性的角度出发,通过轨交无线通信分布系统的工程实例,介绍了典型工程方案的构成及基本思路。通过对轨交的无线电传播环境和多系统间互干扰分析,给出了轨交无线通信分布系统从设计、施工到运营维护整个环节的工程建议。

Reasonable layout of the rail transit radio communication distribution system lays the foundation for good coverage of radio signal in underground areas.With regard to radio-wave transmission characteristics in limited space,by taking work of the rail transit radio communication distribution system as an example,the article introduces composition and basic ideas of typical engineering plans,analyzes radio transit radio transmission environment and interference between systems,and gives engineering recommendations for the whole process,from design,construction to operation and maintenance,of the radio communication distribution system.
