摘要
介绍了既有CBTC(基于通信的列车控制)系统中2.4 GHz DCS(数据通信子系统)的概况,以及5G频段Wi-Fi(无线保真)产品在城市轨道交通中的应用背景。阐述了5G频段Wi-Fi产品应用对城市轨道交通2.4 GHz无线通信可能造成的影响及危害。利用已有的5G频段Wi-Fi产品,对既有CBTC系统2.4 GHz无线信号设备进行现场干扰测试分析。测试结果表明:上海城市轨道交通现有的5G频段Wi-Fi产品对2.4 GHz无线通信不会产生任何干扰和影响。
The general situation of 2.4 GHz DCS(data communication subsystem)in the existing CBTC(communication-based train control)system,and the application background of 5 GHz frequency band Wi-Fi products in urban rail transit are introduced.The possible impact and harm of 5 GHz frequency band Wi-Fi product application on urban rail transit 2.4 GHz wireless communication are expounded.The existing 5 GHz frequency band Wi-Fi products are used to test and analyze the field interference with the 2.4 GHz wireless signaling equipment of the existing CBTC system.The test results show that the existing 5 GHz frequency band Wi-Fi products of Shanghai urban rail transit will not have any interference or impact on 2.4 GHz wireless communication.
