On June 1, 2021, MIIT released a new version of the Guidelines on Radio Frequency Usage of Industrial Internet and Internet of Things. The purpose of the Guidelines is to guide industry users to choose suitable radio communication technologies according to the characteristics of application scenarios, improve the adaptability of industrial applications and frequency resources, and improve the efficiency and benefits of frequency resources. By standardizing frequency usage and station setting, the risk of harmful radio interference is reduced, and the safe and stable operations of related wireless communication systems and the safe production of industrial enterprises are safeguarded.
With the rapid development of radio communication technology, the industrial Internet and the Internet of Things have played an increasingly significant role in upgrading and enhancing traditional industries, and now play an important role in supporting the transformation of the real economy into a digital, network-based and intelligent one. At the same time, the wide application of wireless communication technology and the large-scale connection of production factors have led to a substantial increase in the demand for spectrum. Cases of non-standard use of frequency behavior and mutual interference have occasionally occurred, which also bring risks and hidden dangers to the safe production of industrial enterprises. Therefore, MIIT issued these Guidelines to achieve its dual goals of encouraging innovation while strengthening regulation.
The Guidelines have three main contents. Firstly, they define the principles of “utilization in accordance with the law”, “coordinated development” and “encouraging innovation”, and stress the importance of giving full play to the role of 5G technology and the industry. Secondly, it classifies and analyzes the relevant requirements of national radio management for the use of radio frequencies, radio stations and radio transmitting equipment, including licensing subjects, application requirements, frequency bands and technical standards, etc. Finally, the annex of the Guidelines indicates, for reference, the different frequency of use of the industrial Internet and the Internet of Things in different scenarios.
In regards to wireless communication technology, the Internet industry and the application problems of the Internet of things, the Guidelines point out that the demands for extensive industrial Internet and Internet of things show characteristics like ubiquity, individualization, customization, diversity of technical systems and standards. Wireless communication technology choices need to fully consider application scenarios, the service objects, security control, and operating costs, among other factors. In order to meet the variegated needs of users, particularly in terms of sharing, dedication, convenience, security, individuality, generality, wide area and local area, etc., wireless communication can flexibly adopt one or more technology combinations of public mobile communication systems, private mobile communication system, 2400MHz, 5100MHz and 5800MHz frequency band wireless access system (WLAN) and micro-power short-distance radio transmission equipment. The Guidelines specify, for various technologies, the frequency use range, administrative licensing requirements for frequency use, frequency occupancy fee, interference coordination and other requirements.
