摘要
对CBTC无线通信子系统在隧道中的无线菲涅尔区和无线隧道损耗模型进行计算,提出了无线通信子系统AP设置的合理间距。结合杭州地铁现场环境,对模拟系统进行测试,结果满足设计要求。
This paper describes the structure and implementation of CBTC wireless communication sub- system, presents the calculation of wireless Fresnel zone in the tunnel and wireless loss model for the tun- nel, and proposes how to set reasonable distance among those APs in a wireless communication subsys- tern. According to the configuration of wireless APs in Hangzhou Metro, a simulation system was tested and the results met the design requirements.
