Wu Hequan, academician of the Chinese Academy of engineering, said in the popular science column "Academician's talk" that the number of 5g base stations in China has developed rapidly, but there is still a gap compared with the 4G era. The supporting business of mobile phones is not mature, and it takes time to popularize, so some netizens do not have a strong perception of 5g's "fast". To put it simply, at present, there is no 4G revolutionary application like "short video" on mobile phones. At present, there is no application that can show the ability of 5g, and even the application of 4K and 8K streaming media has not been really used, including the current hot VR and metauniverse services. As a result, the 5g network, which is already the world's leading network in China, is temporarily useless, and we still need some time to develop. He also pointed out that at present, 5g in China is the world's leading system technology and has made great contributions to international standardization. It home learned that the data released by the Ministry of industry and information technology last month showed that at present, 1.615 million 5g base stations have been opened in China, and 5g networks cover all cities, counties, urban areas and 87% of towns and townships across the country. The total number of 5g mobile phone users exceeds 413million. There are 2400 projects under construction of "5g + industrial Internet" and more than 20000 5g application cases. According to the data released by the three major operators, China Unicom had 795million mobile users and 180million 5g package users in May; Chinatelecom had 381million mobile subscribers and 224million 5g package subscribers in May; China Mobile had 967million mobile users and 495million 5g package users in May. Wu Hequan is a communication expert in China. He graduated from Wuhan University of Posts and telecommunications in 1964. He was once the vice president and chief engineer of the Academy of Telecommunications Science and technology, the vice president of the Chinese Academy of engineering, and the president of the China Internet association. He is now the director of the China Standardization Expert Committee. He was elected an academician of the Chinese Academy of Engineering in 1999. Academician Wu has been engaged in the research and development of digital and optical communication systems for a long time. Since 2003, he has successively organized IPv6 project research and test as the director of the national next generation Internet demonstration project expert committee, and organized 3G / 4G / 5G project research and development as the chief engineer of the major special project of the new generation broadband wireless mobile communication technology. In addition, Academician Wu has been responsible for organizing the research of major engineering science and technology consulting projects in recent years. The 30 channel PCM (pulse code communication) terminal equipment developed by him has won the 1978 National Science Conference award, and the 155m / 622m SDH (synchronous digital series) optical transmission system developed by him has won the second prize of the national science and Technology Progress Award in 1988. In 2002, he won the He Liang He Li technology and Science Award. (Xinhua News Agency)
