| 摘 要： | 地铁CBTC信号系统车-地无线通信方案有WLAN和LTE 2种.本文针对这2种不同的车-地通信方案,从无线系统架构、无线设备分布、数据吞吐量、支持的最高列车速度、无线传输性能、抗干扰性能、无线系统的复杂程度等方面进行对比分析,对新建地铁线路及既有采用WLAN方案的线路延伸线的车-地无线通信方案进行选择,具有一定的指导意义.

| Abstract: | WLAN and LTE are two kinds of solution to train-ground radio communication of the CBTC signal system for metro.The two solutions are compared in aspects of architecture of radio system,distribution of radio equipment,data throughput,allowable highest train speed,radio transmission performance,anti-interference performance and complexity of radio system.The comparison results may be used for the selection of CBTC train-ground solution for newly-built metro line or the extension of existing metro line in which WLAN is adopted. |
