Guide At present, the global information technology revolution represented by the Internet of things and the mobile Internet is driving a new round of industrial transformation. The wireless technology gradually penetrates into all fields and links of industrial manufacturing and presents from information collection to production control. From the local solutions to the whole Network program development trend. At present, wireless technology is mainly used for information collection, non-real-time control and factory internal information, etc. Wi-Fi, Zigbee, 2G / 3G / LTE, WIA-PA, WirelessHART and ISA100.11a for industrial process automation Technology is partially used in the factory. At the same time, wireless technology is gradually penetrating the field of industrial real-time control and becoming a powerful supplement or alternative to existing industrial wired control networks. In order to better promote the development of China's industrial internet industry, it is suggested that the development of industrial internet wireless technology frequency planning should be started as soon as possible from the following three aspects. Optimize the frequency planning of short-range micropower devices It is recommended to optimize existing free license frequencies. Research and formulate the transmit power and sharing standards for short-range micro power devices, promote R & D innovation of related system interference cancellation technologies, enhance system anti-interference ability, and enhance coexistence ability of different systems in the licensed spectrum. At the same time, it plans scientifically the license-free frequencies such as short-range micropower and further revise and improve the existing short-range micropower standard documents. Promote long-distance transmission technology research and frequency planning Support NB-IoT technology related frequency band test and business pilot. According to the actual needs of China's telecommunications development, and actively promote the coordination of 821-824MHz / 866-869MHz frequency band to carry out NB-IoT test work. At the same time, it coordinates the three major operating companies and recommends that telecom operators make full use of existing 2G, 3G and 4G spectrum resources for heavy-land use to meet the demand for spectrum resources outside the industrial Internet factory in the future. 5G band planning and testing. Consider dividing dedicated frequencies for industrial Internet wireless applications In the future, the scale of industrial networks will continue to expand, the number of connections will continue to increase, and the data throughput rate will continue to increase. Accordingly, the frequency requirements of various types of wireless technologies in the industrial internet will also increase. In some industrial internet applications, the requirements for real-time and reliability of wireless communications are very high. In order to ensure the frequency-use security of such wireless communications, a dedicated frequency should be planned for wireless communications in the industrial Internet.
