Chinese passengers taking high-speed rail are soon to end their days suffering from weak network signals as Wi-Fi is to be installed on the trains in December, Xinhua News Agency reports. 新华社报道,乘坐高铁的乘客将不再受到网络信号差的影响,12月高铁车厢中将提供Wi-Fi信号。 Satellite transceivers, devices used for transmitting Wi-Fi signals, have been installed on trains for further testing. It is estimated that the Wi-Fi will be officially up and running by December. The transceiver was developed by the 29th research institute of China Electronics Technology Group Corporation (CETC). Zhang Jie, a senior engineer from the institute says that the highest speed of high-speed trains in China now runs at 350 km per hour, and their technology helps the Wi-Fi signal to be uninfluenced by a train traveling under 500 km per hour. However, the number of users should not surpass 700, but since current high-speed trains have a capacity of around 560 people, the technology is fine for now.
