The railway train WiFi system provides an integrated wireless information application platform, which can provide rich information and entertainment applications for passengers, and also provides a management platform for passenger transport management departments. The system was jointly designed and developed by Tian Fei United Company, Southwest Jiaotong University and the Ministry of Railways.
I. Application History
From 2065438 to September 2003, the railway train Wi-Fi was first installed on the K9092 train from Changsha to Changde and the K9075 train from Changde to Shenzhen East, and put into trial operation. During the period of 2065438+2004 in Spring Festival travel rush, Guangzhou Railway Group further strengthened the renovation of train equipment and facilities, and installed 280 wireless Wi-Fi devices on the underbody of 23 sets of ordinary-speed passenger cars originated in Hunan, which brought passengers a brand-new ride experience, which was the first time in China. ?
20 14 1, WAPI industry alliance said that the first "high-speed train WiFi system" in China to provide wireless LAN services for railway passengers has been successfully developed. China's first "high-speed train WiFi system" providing wireless LAN services for railway passengers has been successfully developed and will be put into use on some trains. Telecommunications Research Institute of the Ministry of Industry and Information Technology, WAPI Industry Alliance and Tian Fei jointly formulated the technical standards related to on-board wireless LAN for rail transit. The series of standards have all been completed, and the demonstration operation of standard products is being submitted to the relevant railway departments, and it is expected to be put into use on some trains in the near future.
201feb/April 18, 20 14, two wireless Wi-Fi devices were installed on 23 groups of ordinary speed buses originating from Hunan. In the train compartment where the "Wireless Wi-Fi Passenger Train Integrated Service System" is installed, passengers only need to turn on the Wi-Fi function of their smartphones or computers, and then connect to the Internet in their browsers, so they can access the railway train Wi-Fi system for free. Guangzhou Railway Group said that only some ordinary customers from Hunan can surf the Internet for free. Due to technical reasons, high-speed rail and bullet trains will not have wireless Wi-Fi coverage for the time being.
Second, the main functions
Wifi system includes train theater, passenger information, travel guide, etc. You can inquire about ticket purchase, train timetable information, as well as city attractions, hotel reservations and catering information along the way. For passengers, the most attractive thing is the train cinema, which has nearly 200 Chinese and foreign movies for passengers to watch on the road without worrying about being disconnected.
Wifi system mainly overcomes 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 the third is to meet the needs of network speed. Through real-time data storage of common information on the server side, users can have a better online experience. ?
