The guidelines for the construction of 5g fully connected factories issued by the Ministry of industry and information technology of China on the 6th put forward that during the 14th Five Year Plan period, 10000 enterprises should be promoted to carry out the construction of 5g fully connected factories. 5g fully connected factory is an advanced factory that makes full use of the new generation of information and communication technology integration represented by 5g, creates a new industrial Internet infrastructure, builds or renovates production lines, workshops, factories and other production sites, and forms extensive connection of production units, deep integration of information (it) operations (OT), full utilization of data elements, and high-efficiency empowerment of innovative applications. It is proposed in the guidelines that during the "14th five year plan" period, 10000 enterprises will be promoted to carry out the construction of 5g fully connected factories, build 1000 classified and graded factories with bright characteristics, and build 100 benchmark factories, mainly for the manufacturing industries such as raw materials, equipment, consumer goods, electronics and other key industries such as mining, ports and power. The guide proposes integrated innovation and coordinated development. Integrate the resources of industrial enterprises, basic telecom enterprises, 5g terminal and network equipment manufacturers, vertical industry solution providers and other parties, work together to promote the implementation of 5g fully connected factories in key industries and fields, and promote the integrated development of innovation chain, industry chain and supply chain. The construction of 5g fully connected factories will be implemented by classification. The new factory is designed and built in one. The existing factory is based on reality, urgent needs first, and promotes the construction of 5g fully connected factories by industry, classification and classification. In key industries and fields, we will promote the development of business entities with a good foundation and clear needs, take the lead in building 5g fully connected factories, and form a benchmark for digital, networked and intelligent transformation and upgrading.
