The process of "5G changing society" is still on the way, and iconic phenomenon level 5G applications have not yet emerged. How to fully leverage the value of 5G networks and create a more mature global industrial ecosystem is an important issue that needs to be carefully considered and promoted for resolution. It has been more than 4 years since China issued its 5G commercial license in 2019. What are the achievements of 5G commercial use? Reporters learned from the 2023 Shanghai World Mobile Communication Conference (hereinafter referred to as the "Conference") that by the end of May this year, China had built and opened a total of 2.844 million 5G base stations, covering all Prefecture-level city and county cities. 5G applications have been integrated into 60 out of 97 national economic categories, with a cumulative number of application cases exceeding 50000. Currently, China has built the world's largest and most advanced 5G network. The 2023 China Mobile Economy Report by the Global Association of Mobile Communication Systems (GSMA) points out that China is the world's leading 5G market. As of the end of 2022, China accounts for 60% of global 5G connections, and operators are increasingly turning to 5G industry applications. From "3G breakthrough" to "4G synchronization", China's communications industry has now achieved a leap to "5G leadership", and is targeting a new journey of 6G R&D. During the conference, China Mobile showcased many 5G application cases to accelerate the upgrade from "built well" to "used well". Li Huidi, Deputy General Manager of China Mobile, stated that currently, China Mobile has 480 million 5G terminal customers, with a 5G network diversion ratio of over 50% and over 23000 5G commercial cases; With the completion of 360000 5G base stations in 2023, the population coverage rate will exceed 90%. During this conference, operators also showcased 5G new calls, which are innovative applications and value-added services that integrate multimedia communication, artificial intelligence technology, and computing power networks. They have been tested for commercial use in some pilot provinces in June and will achieve full network scale commercial use this year. On the basis of operators' audio and video calls, they can integrate digital people's interesting calls, real-time translation, AI assisted calls, remote assistance, and other scenarios, visualizing Stronger interactivity. Compared to previous generations of telecommunications technology, the advantage of 5G lies in its industry application. For example, the smart mine application supported by 5G can enable the mine to achieve "unmanned operation", which can not only reduce costs and increase efficiency, but also help safe production. 5G also has a broad application prospect in smart education, medical care, cultural relics, Internet of Things, Vehicle-to-everything and other industrial scenarios. Zhao Zhiguo, Chief Engineer of the Ministry of Industry and Information Technology, stated that China's 5G construction deployment and scale application have been solidly promoted, accelerating the upgrade from "well built" to "well used". In terms of network construction, China has built over 16000 virtual private networks in the 5G industry; In terms of technological innovation, we have created a relatively complete industrial chain of 5G systems, chips, terminals, instruments, etc; In terms of integrated application, 5G application in the industrial field has gradually penetrated into the core links of production and operation. For example, the 5G+emergency treatment system has been built and used in more than 70 Prefecture-level city, and the 5G application of the top 50 coal enterprises in China accounts for 72%.
