The traditional wireless private network generally mainly uses Wi-Fi, Bluetooth, RFID radio frequency and industrial wireless technologies, and the traditional wireless private network has the problems of unstable performance, poor terminal mobility, limited coverage range and the like. And because the networks of various systems come from different suppliers and at different periods, the background cannot be communicated and the frequency band has interference. Large industrial enterprises often have more than one production site, and therefore, it is also a basic requirement of the enterprises to achieve interconnection among multiple plant areas. In the face of the contradiction between wide area connection and security, the traditional mobile communication network with general service faces huge challenges, and the wired private network faces a large number of mobile scenes and is still inelegant.
