"Providing WiFi access on high-speed trains has specific technical requirements, which is very different from the access service in the home office environment. The high-speed train WiFi system provides an integrated wireless information application platform, which can provide passengers with rich information and entertainment applications, and also provide a management platform for the passenger transport management department. " Duan Shiping, CEO of Tian Fei United Company, one of the main R&D units of the system, said.

Duan Shiping said that the system mainly overcame three technical difficulties. First of all, we must meet the requirements of "getting on the train" and run well in the high-speed train. The second is to meet the signal requirements, and at the same time access to the 3G/4G wireless communication networks of China Mobile, China Telecom and China Unicom to realize smooth signal access. Third, to meet the demand of network speed, users can have a better online experience through real-time data storage of common information on the server side.

"The on-board WiFi system designed and tested by Tian Fei United Company, Southwest Jiaotong University and the railway department has been tested for one year and is expected to be put into use on Chengdu-Chongqing trains in the near future." Duan Shiping said.

It is reported that the Telecommunications Research Institute of the Ministry of Industry and Information Technology, WAPI Industry Alliance, Tian Fei United and many other units have previously formulated technical standards related to on-board wireless LAN for rail transit. At present, the series of standards have all been completed and are being reported to the relevant railway departments for demonstration operation of standard products.
