In the past three years, China's 5g development has entered a critical period. The reporter learned from the 2022 World 5g Conference opened on August 10 that the typical application scenarios of 5g are integrated into 40 categories of the national economy and have been applied on a large scale in mines, ports and other fields. In the next step, relevant departments will carry out the construction of 5g network in a steady and orderly manner in accordance with the principle of moderate advance. At the same time, they will vigorously support the integration and development of 5g with vertical industries such as industry, energy and medical care, comprehensively promote the commercial deployment and large-scale application of 5g, and cultivate and expand new drivers of economic development. "Hello, command center, this is the intelligent fully mechanized mining face. Now please authorize the remote startup..." with the staff pressing the start button, the whole set of fully mechanized mining units in the intelligent fully mechanized mining face of Chengshan mine of Jixi mining company of Longmei group was successfully started. With the help of the underground 5g network, the ground personnel can see the automatic operation of the coal mining equipment of the underground working face through the electronic screen, such as coal cutting, rack moving, sliding and conveying, and the operation scene is panoramic. Not only that, the inspection robot can collect and transmit downhole data in real time; The staff conduct clear and smooth video communication through underground mobile phones, which provides convenience for underground command and dispatching and emergency rescue. "The 5g network has the characteristics of large bandwidth, low delay and wide connection. It has broken through the bottleneck of the previous underground and underground communication and data transmission, and provided reliable support for the intelligent management, intelligent ventilation, intelligent coal mining and intelligent transportation of coal mines." Longmei group Jixi Mining Company electromechanical professional principal said. In Fujian, entering the "5g + smart factory" jointly built by Ningde times and China Mobile, hundreds of AGV smart cars are shuttling back and forth to transport materials, running in an orderly manner. On the production line, the central intelligent process perception control system connects all the equipment and instruments related to the coating machine in the workshop, and cooperates with AI technology for automatic management to solve the problems such as complicated manual operation. "We have explored 22 high-value business scenarios. At present, 9 kinds of 5g integrated applications have been implemented, and we are accelerating towards the goal of a 5g factory." Ningde times related person in charge said. At present, it has been three years since 5g was put into commercial use in China, and the construction and application of 5g have achieved positive results. The reporter learned from the conference that as of June, China had built 1.854 million 5g base stations, covering all cities, county towns and 92% of townships and towns in the country. The number of 5g mobile users reached 455 million, and the number of 5g base stations and users accounted for more than 60% of the world. In terms of application promotion, 5g typical application scenarios are integrated into 40 of 97 major categories of the national economy, and large-scale applications are realized in mines, ports and other fields. "China's 5g construction has made breakthrough achievements and has entered all aspects of social life. Significant progress has been made in the application of industrial Internet, smart cities, smart villages and other fields. We are constantly exploring new scenarios of uplink ultra wideband, real-time broadband acceleration and perceptual positioning." Said Wu Hequan, academician of the Chinese Academy of engineering and chairman of the future mobile communication forum. With the continuous advancement of convergence applications, 5g is accelerating the development of digital economy. According to statistics, the accumulated investment in 5g of national operators is 401.6 billion yuan, plus the consumption of mobile traffic, mobile information services, etc
