摘　　要：Wi-Fi技术在城市轨道交通建设中有着大量的应用,随着Wi-Fi技术的不断迭代更新,不同时期建设的城市轨道交通往往采用的是不同版本的Wi-Fi协议标准。文章结合深圳地铁6号线支线的Wi-Fi 6车载无线AP设备在6号线长圳车辆段部署的Wi-Fi 5网络下运行的情况,从信号接收电平、传输速率、时延和丢包率等维度对Wi-Fi 6设备在Wi-Fi 5网络下的运行表现进行研究分析。Wi-Fi technology has a large number of applications in urban rail transit construction.With the continuous iteration and updating of Wi-Fi technology,urban rail transit constructed in different periods often adopts different versions of Wi-Fi protocol standards.Combining the operation of the Wi-Fi 6 on-board wireless access point(AP)equipment of the branch line of Shenzhen metro line 6 in the Wi-Fi 5 network deployed in the Changzhen depot of line 6,this paper studies and analyzes the operation performance of the Wi-Fi 6 equipment in the Wi-Fi 5 network from the dimensions of reception signal level,transmission rate,delay time and packet loss rate.
