As a new generation of mobile communication technology, 5G technology meets the application requirements of wireless network in traditional manufacturing enterprises' intelligent manufacturing transformation, and can meet the requirements of equipment interconnection and remote interactive application in industrial environment. In the fields of Internet of Things, industrial automation control, logistics tracking, industrial AR, cloud robots and other industrial applications, 5G technology plays a supporting role.

(1). Internet of Things: With the advancement of intelligent transformation of factories, Internet of Things (IOT), as a key supporting technology for connecting people, machines and equipment, is attracting great attention from enterprises. This demand not only promotes the application of the Internet of Things to the ground, but also greatly stimulates the development of 5G technology.

(2) Industrial automation control: This is the most basic application in manufacturing plants, the core of which is the closed-loop control system. 5G can provide extremely low time extension, high reliability and mass connection network, which makes it possible for closed-loop control applications to connect through wireless networks.

(3) Logistics tracking: From warehouse management to logistics distribution, it needs wide coverage, deep coverage, low power consumption, broad connection and low cost connection technology. In addition, end-to-end integration of virtual factories spans the whole life cycle of products. To connect widely distributed sold goods, low-power, low-cost and wide-coverage networks are also required. Horizontal integration within enterprises or between enterprises also requires ubiquitous networks. 5G networks will well meet such needs.

(4) Industrial AR: in the production process of intelligent factory, people play a more important role. Because of the high flexibility and versatility of future factories, there are higher requirements for workshop staff. Augmented Reality AR (AR) will play a key role in rapidly meeting the needs of new tasks and production activities. AR can be used in the following scenarios in intelligent manufacturing process: monitoring process and production process. Step by step guidance of production tasks, such as manual assembly process guidance; remote expert business support, such as remote maintenance. In these applications, auxiliary AR facilities need to be flexible and portable to the greatest extent in order to carry out maintenance work efficiently.

(5) Cloud Robots: In intelligent manufacturing production scenarios, robots need the ability of self-organization and collaboration to meet flexible production, which brings the need for Cloud Robots. 5G network is the ideal communication network for Cloud Robots and the key to enable Cloud Robots.

Summary: 5G technology has become the key enabling technology to support the transformation of intelligent manufacturing. It can connect the widely distributed and scattered people, machines and equipment to build a unified Internet. The development of 5G technology can help manufacturing enterprises get rid of the chaotic application state of wireless network technology in the past, which has a positive significance for promoting the implementation of industrial Internet and deepening the transformation of intelligent manufacturing.
