On May 17, the reporter learned from the 2022 World Telecommunication and information society day conference that at present, China has built nearly 1.6 million 5g base stations, becoming the first country in the world to build 5g network on a scale based on independent networking mode. Next, the Ministry of industry and information technology will "moderately advance" to speed up infrastructure construction, promote the construction of 5g, gigabit optical network and data center, and improve the depth and breadth of coverage; Seize the critical period of 5g large-scale application, accelerate the upgrading of industrial Internet, and continue to cultivate development momentum. Zhang Yunming, member of the Party group and vice minister of the Ministry of industry and information technology, introduced on the same day that at present, China's infrastructure is more solid and powerful, and the comprehensive capacity has been improved by leaps and bounds. Fixed broadband has been upgraded from 100m to Gigabit, and the proportion of optical fiber users has increased from less than 10% in 2012 to 94.3% in 2021. As of March 2022, the number of IPv6 active users in China accounted for 63.01% of all Internet users, and the applied IPv6 address resources ranked first in the world. At the same time, innovation and application are more extensive and in-depth. China has formed the largest and most active digital service market in the world. 5g applications cover many life fields such as transportation, medical treatment, education, culture and tourism, with a total of more than 20000 cases. The industrial Internet has been applied to 45 major categories of national economy, covering R & D and design, production and manufacturing, marketing services and other links, and the industrial scale has exceeded the trillion yuan mark. It is reported that in the next step, the Ministry of industry and information technology will make overall planning and moderately advance to speed up infrastructure construction. Among them, we will systematically promote the construction of 5g, gigabit optical network and data center, deepen the integration of digital network, computing network and cloud side collaborative development, and improve the depth and breadth of coverage. Promote the transformation and upgrading of traditional infrastructure by new technologies such as big data, cloud computing, artificial intelligence and blockchain, and build a leading edge in technological innovation. Promote digital infrastructure, help the construction and development of intelligent transportation, smart grid, smart water conservancy and smart city, and build a solid support for integrated development.
