Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizen Xiao Zhan for the clue delivery! CTOnews.com February 1 news, according to the website of the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology "notice on microwave communication system frequency use planning and radio management" (hereinafter referred to as "notice") will come into effect today (February 1, 2023) to optimize and adjust the frequency use planning of microwave communication system in China.

The Ministry of Industry and Information Technology said that the notice conforms to the new situation and requirements of the development of China's microwave communication industry, combined with the new scene and new mode of the application of microwave communication system, through the frequency use planning of microwave communication system with new millimeter wave band and large bandwidth, optimizing the frequency and channel bandwidth of existing microwave communication system in middle and low frequency band, adjusting microwave channel configuration to be in line with international standards, and so on. Further meet the needs of high-capacity information transmission (microwave return) scenarios such as 5G base stations, and reserve spectrum resources for China's 5G, industrial Internet and future 6G, to better meet the needs of high-quality development of radio industries such as microwave communications.

CTOnews.com learned that the notice points out that the frequency bands available for the adjusted microwave communication system are: 4500-4800MHz, 7125-7725MHz, 7725-8500MHz, 10.7-11.7GHz, 12.75-13.25GHz, 14.5-15.35GHz, 21.223.6GHz and 71-76GHz / 81-86GHz.

The notice also specifies the permission and usage requirements for frequency use. The microwave communication link involves three or more provinces (autonomous regions and municipalities) and cross-border microwave communication systems, and the frequency use license shall be implemented by the national radio administrative agency; in other cases, the frequency use license shall be implemented by the local radio administrative agency. The frequency band occupation of the microwave communication system shall not be less than 80%, and the annual time occupation shall not be less than 60%.

In addition, the "notice" defines the requirements for the management of microwave stations, requirements for radio transmission equipment, and frequency coordination, and puts forward relevant work requirements during the transitional period of microwave frequency planning and adjustment.
