China SRRC News about 2400MHz, 5100MHz and 5800MHz frequency Management
1、 The 2400MHz, 5100MHz and 5800MHz frequency bands are divided into radio services such as fixed, mobile, radio positioning, satellite fixed, satellite earth exploration, satellite radio measurement and space research. The 2400MHz and 5800MHz frequency bands are also designated as non-radio equipment radiating radio for industrial, scientific and medical (ISM) applications generating radio frequency energy. No radio station or equipment shall exclusively or exclusively use frequencies in 2400MHz, 5100MHz and 5800MHz frequency bands.
2、 According to the corresponding radio frequency division of mobile or fixed services, the 2400MHz frequency band can be used for radio communication systems such as broadband wireless access (including WLAN), Bluetooth, point-to-point transmission, etc.; 5100MHz frequency band can be used for radio communication systems such as broadband wireless access (including wireless LAN), and can only be used indoors (not included in the car); 5800MHz frequency band can be used for broadband wireless access (including wireless LAN), point-to-point transmission, electronic non-stop charging and other radio communication systems.
3、 The RF unit and antenna of radio transmitting equipment working in 2400MHz, 5100MHz and 5800MHz frequency bands must be designed and produced in accordance with integration or synchronous matching, and other antennas or additional RF power amplifiers shall not be used without authorization; The transmitting equipment shall meet the technical requirements and obtain the model approval certificate of radio transmitting equipment according to law (except micro power short-range radio transmitting equipment).
4、 In order to achieve compatibility and coexistence with other service frequencies such as radio positioning, radio transmitting equipment working in 5250-5350MHz frequency band shall adopt transmission power control (TPC) and dynamic frequency selection (DFS) interference suppression technology, and shall not set the option of turning off DFS. TPC range shall not be less than 6dB; If there is no TPC function, the equivalent isotropic radiated power and the spectral density limit of equivalent isotropic radiation power shall be further reduced by 3dB compared with the corresponding limit.
In order to realize the compatible coexistence of different radio service frequencies, radio transmitting equipment operating in 2400MHz, 5100MHz and 5800MHz frequency bands shall meet one of the technical requirements for interference avoidance.
Wireless LAN equipment with public network IP address allocation function shall support IPv6 protocol and enable IPv6 address allocation function by default. For WLAN equipment with special national requirements for information security, the security capability of air interface access control shall also comply with GB 15629 national WLAN security series standards.
5、 If a wireless local area network access point (AP), a central station of a broadband wireless access system, or a wireless station for point-to-point transmission is set up and used, and the following conditions are met at the same time, it shall apply to the local radio administration of the province, autonomous region, or municipality directly under the central government for a radio station license:
（1） set up in outdoor environment;
（2） The equivalent isotropic radiation power of radio transmitting equipment operating in 2400MHz frequency band is greater than 20dbm; The equivalent isotropic radiation power of radio transmitting equipment operating in 5800MHz frequency band is greater than 30dBm.
In addition to meeting the above conditions, the establishment and use of other radio transmitting equipment and radio stations in 2400MHz, 5100MHz and 5800MHz frequency bands shall be managed with reference to the ground public mobile communication terminal without obtaining a radio station license.
7、 The radio stations with 5100MHz frequency band shall be more than 3km away from the earth stations of satellite radio measurement (air to ground) service and satellite fixed (air to ground) service in the same frequency band legally used. The relevant satellite earth stations shall set obvious signs at the road crossings within 3km, indicating that the setting and use of 5100MHz frequency band radio stations are prohibited.
11、 Micro power short-range radio transmitting equipment in 2400MHz and 5800MHz frequency bands shall be implemented in accordance with the relevant provisions of Announcement No. 52 of the Ministry of industry and information technology in 2019.
13、 From October 15, 2023, the application for model approval of radio transmitting equipment shall be implemented in accordance with the technical requirements listed in this notice.
14、 The relevant requirements of this notice shall come into force as of January 1, 2022. If the previous relevant provisions are inconsistent with this notice, this notice shall prevail.
