[0002] Rail transit is one of the products of urban high-speed development, and the development and construction investment of urban rail transit system is increasing. Passenger information system is an important part of vehicle communication, and its development and increasingly reliable operation is one of the focuses of rail transit construction development. Compared with wired network technology, the reliability of wireless communication in passenger information system application needs to be studied. With the popularity of smart phones, the number of passengers using smart devices for entertainment in the carriage increases, and when the vehicle shuttles different sections, Wi-Fi signal and Wi-Fi rate will fluctuate, affecting the online experience of passengers. To meet the urgent needs of passengers for high-speed network, improve Wi-Fi signal and Wi-Fi rate, and improve the level of metro informatization construction, the train-ground communication scheme based on wireless local area network technology is increasingly valued. Wireless local area network can provide higher bandwidth, more stable Wi-Fi signal, and wider access control, meeting the various business needs of operators. Currently, passengers can use the following two ways to access the Internet. Scheme one, mobile phone opens data service and uses 5G / 4G to access the Internet. The mobile phone opens data and uses the traffic package provided by the three major operators to access the Internet. The disadvantage of this method is that in areas where the signal cannot be covered, the signal will be unstable and the transmission rate will be too low. Scheme two, vehicle WiFi access the Internet. The passenger's mobile phone terminal is connected to the WIFI signal on the train, and the on-board WIFI device is inserted into the local operator's SIM card. After authentication, it uses 5G / 4G data networking. Scheme two and scheme one are essentially the same, except that in scheme two, the passenger's mobile phone is not directly connected to the base station near the track, but is connected by the on-board device. The bottleneck of online experience is still between the train and the ground, and the communication link is the 5G / 4G signal of the public network. Only the public network signal is converted to WIFI, and the network quality depends on the coverage of the public network to the train, so the situation of unstable signal and too low transmission rate cannot be avoided.
