The 75 trains of the WiFi train are installed at the fastest speed in the end of April.
, in the future, the train can also rub the network brush friends circle to see video! Reporter learned from the railway department, the fastest April at the end of April, some trains can complete free WiFi system loading debugging, passengers can enjoy the Internet service by train.
reporter learned from the Ji'nan Railway Bureau, the installation of this free WiFi, the Ji'nan Bureau has 75 sets of train installation and commissioning, distributed in Ji'nan to Qingdao, Xi'an, Beijing and other lines. In addition to Ji'nan, there are more than 100 trains in Beijing Railway Administration carrying out the commissioning of free WiFi system. It is revealed that the free train WiFi service project is jointly operated by the railway administration and the Zhong Chuan group. The more than 100 sets of trains from the Beijing Railway Bureau are distributed in Beijing to Shanghai, Qingdao, Kunming, Guangzhou, Lhasa and other routes, and Tianjin and Yanjiao near Beijing are also in the middle of the plan, which are not included. High speed rail and motor train. Most of the trains are expected to be completed by the end of March. After testing, the free WiFi networking service will be provided for passengers at the end of April. Introduction of the relevant personnel of China Communications Group, cooperation with the high-speed rail is still under negotiation. The way to access the Internet is the APP network, which has passed through the security audits of the railway sector, which is more secure than direct networking or access to web windows.
it is understood that at present, the WiFi on the train has some technical difficulties. It generally converts the 3G or 4G signals along the line to WiFi through the vehicle WiFi equipment, that is, to receive the network signals of the three major operators along the route through the equipment, and turn it into the WiFi hot spot on the train for the passengers to use. However, in the speeding train, how to ensure that WiFi's good experience may be tested. When the train reaches 200 to 300 kilometers per hour, the signal attenuation is very large. And frequent switching between the three operators network, the signal will be unstable. In addition, in sparsely populated areas, if the coverage density of the base station is not large enough, the signal will be affected. If the satellite signal is transmitted, the cost is too high and the technology is not mature.
