| Abstract: | The introduction of mobile communication 3G/4G signal in urban rail transit represents the general trend of de-velopment. In this paper,issues of 3G/4G general signal intro-duction in Guangzhou subway network are addressed,their in-terferences 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. |
