High speed rail ushers in "new passenger-5g"

In recent years, 5g, the fifth generation mobile communication system, has become a hot topic in the communication industry and academia. The development of 5g has two main driving forces. On the one hand, 4G, the fourth generation mobile communication system represented by long-term evolution technology, has been fully commercial, and the discussion on the next generation technology has been put on the agenda; on the other hand, the demand for mobile data has exploded, and the existing mobile communication system is difficult to meet the future demand, so it is urgent to develop a new generation 5g system.

under the sustained and rapid development of China's economy, in order to meet the needs of all walks of life, Chinese researchers took the lead in completing 5g business operation. The Chinese people are writing the great revival of colorful music with their hard-working hands

with China Mobile, China Unicom and China Telecom announced the opening of 5g commercial operation on October 31, China officially entered the 5g era As one of the "four great inventions" of the new era, the high-speed rail EMU has concentrated the cutting-edge technology and top technology in various fields in China. The new era technologies such as high-speed rail WiFi, touch-screen operation mode, intelligent operation mode and so on have been displayed incisively and vividly on the intelligent high-speed rail of Beijing Zhangjiakou Railway, which is about to open to traffic With the commercial and continuous development of 5g network and the implementation of "electronic ticket", China's high-speed rail is moving towards a comprehensive intelligent road
