In recent years, IoT systems based on various sensors have had a major impact on people’s lifestyles and industries. Given the dynamics of the IoT-based device manufacturing process, it is estimated that by the end of this year, 1,000,000,000 devices will be developed and used in industry worldwide. However, the use of wireless networks to exchange data between such devices is becoming a major problem. Therefore, the use of a 5G network is currently considered as the optimal solution for IoT systems designed for industrial automation.

This chapter is devoted to the existing technologies of using 5G network for IoT and solutions to apply them in industrial automation. Initially explored in this chapter are the possibilities of using a 5G network for IoT, types of communication, network technologies, and management issues and the possibilities of processing edge computing, big data, and mobile cloud computing. Also, the 5G-enabled IoT architecture, structure, and construction principles are analyzed.

Several stages of applying 5G-enabled IoT systems in industrial digitization and important information on the requirements for their indicators in industrial automation, such as requirements for data rate, scalability, reliability, latency, resilience, long battery lifetime, and connection density, mobility, and security, have been analyzed.

Also, the existing technologies (such as WNFV, HetNet, D2D, M2M, massive MIMO, and 5G-enabled IoT for industrial purposes) currently used in 5G-based IoT for industrial automation have been studied, and their solutions such as requirements of 5G network and resource allocation optimization have been explored.
