广州地铁引入通用移动通信的干扰测试研究

Introduction of Mobile Communications Interference Test in Guangzhou Metro

城市轨道交通引入通用移动通信3G/4G信号是大势所趋。为此,探讨了地铁线路引入通用3G/4G信号后可能会造成信号干扰等问题,并对广州地铁现有通信设备进行了干扰测试。根据测试结果,提出了相应的抗干扰措施建议,以避免移动通信信号对地铁运行造成干扰。

The introduction of mobile communication3G/4G signal in urban rail transit represents the general trend of development.In this paper,issues of3G/4G general signal introduction in Guangzhou subway network are addressed,their interferences over the existing devices in Guangzhou metro are discussed,corresponding suggestion are proposed based on field testing results.The purpose is to reduce the losses caused by the signal interference over metro devices.
