Recently, the Ministry of Industry and Information Technology issued the Guidelines for the Construction of 5G Fully Connected Factories, proposing that during the "Fourteenth Five Year Plan" period, thousands of enterprises should be encouraged to carry out the construction of 5G fully connected factories, build 1000 factories with distinctive characteristics and classification, build 100 benchmark factories, and promote the in-depth development of 5G integrated applications. At present, the industrial Internet can be described as the "main battlefield" of 5G. China Telecom has taken the lead in the integration and innovation of 5G+industrial Internet, giving the manufacturing industry the wings of industrial Internet. 5G+Industrial Internet Promotes 5G Industrial Development China has been promoting the development of industrial Internet. As early as 2017, the State Council issued the Guiding Opinions on Deepening "Internet+Advanced Manufacturing Industry" and Developing Industrial Internet; In 2019, the Ministry of Industry and Information Technology issued the "5G+Industrial Internet" 512 Project Promotion Plan, which defined the industrial Internet construction plan. Recently, the Ministry of Industry and Information Technology issued the Guidelines for the Construction of 5G Fully Connected Factories, which helps to provide direction and goals for the transformation and upgrading of traditional industries using 5G, and promote the in-depth development of 5G integrated applications. At present, thanks to the continuous development of the industrial Internet, the 5G field in China has also continued to grow, and the 5G glow cannot be separated from the industrial Internet application scenario. "5G+digital factory" makes the factory more intelligent, "5G+smart mine" makes the production more efficient and safe, "5G+industrial park" helps the industrial intelligent manufacturing upgrade, and the deep integration in the 5G+industrial Internet field has spawned one excellent application case after another, which has inserted wisdom wings for the industrial manufacturing industry. It is not difficult to predict that the penetration rate of 5G in the industrial Internet field will gradually increase in the future. Give play to the advantages of 5G cloud network, China Telecom deepens its industrial Internet as the main force in building new infrastructure. China Telecom actively undertakes the national industrial Internet strategy, lays out the domestic leading industrial Internet public platform, and provides benchmark cases for the transformation and upgrading of traditional industries. In Shandong, China Telecom Shandong Qingdao Branch successfully built the first 5G customized private network project in the refrigerator manufacturing industry, and successfully built a 5G+intelligent factory for Qingdao CIMC refrigeration industry base using the "Be Neighbor" model. In Guangxi, China Telecom Liuzhou Branch actively promoted the digital transformation of Liuzhou United Auto, built a 5G+industrial Internet platform for customers with the 5G+cloud+industrial big data platform as the core, and continued to improve the construction of smart factories to make automobile production more efficient and intelligent. In Sichuan, China Telecom Chengdu Branch helped Hongfujin Precision Electronics Chengdu SMT Factory to achieve intelligence and automation. Taking advantage of the core capabilities of 5G cloud network and the independent networking of SA, a number of innovative applications of industrial Internet have been created through the advantages of 5G high-speed, large connectivity, low latency, etc. It is imperative to upgrade the industrial Internet industry. Feng Xu, vice president of the China Industrial Internet Research Institute, said that the industrial Internet is a new engine to promote the sustainable and high-quality development of China's economy, and the industrial Internet platform is playing an important role.
