1) in-situ wireless surveying
无线勘测
1.
Considering a signal project on Shanghai urban rail transit line 8,the paper studied and presented the theoretical RF signal transmission model of the R-CBTC data communication system in tunnels,and studied the transmission characteristics of the wireless signals in tunnels by the theoretical model and the in-situ wireless surveying.
结合上海市城市轨道交通8号线的信号工程,研究并提出隧道中无线CBTC数据通信系统的无线射频信号理论传播模型;从理论模型和实地无线勘测的角度,对无线信号在隧道中的传播特性进行研究及分析。
