城市轨道交通线路高架区间无线通信方案浅论

摘要

The way of space wave coverage based on installing antenna or laying of coaxial - cable leak- age can be used to solve problems which related to weak wireless field of elevated railway in urban rail transit system. Combined with the repeater, various technical proposals about these problems could be derived. This paper mainly discusses three solutions, which respectively focus on setting up station anten- na, installing station antenna and directly repeater station, and laying of coaxial cable leakage.%城市轨道交通高架区间场强覆盖弱区,通常可以采用架设天线作为辐射源的空间波覆盖方式及敷设漏泄同轴电缆作为传输线和分布天线的覆盖方式加以解决,结合区间中继设备又可衍生出多种解决方案。重点讨论基站天线覆盖方案、基站天线＋直放站天线方案和敷设漏泄同轴电缆方案。
