Environmental protection inspection exemption for communication base station energy management system

At present, the national standard for electromagnetic radiation protection, "Electromagnetic Radiation Protection Regulations" (GB8702-88), stipulates that when the equivalent radiation power of the electromagnetic radiator is less than 100W (50dBm) within the current mobile communication frequency band, an electromagnetic environment exemption can be implemented; when the equivalent radiation power of the electromagnetic radiator is greater than 100W (50dBm), an "Environmental Impact Report (Form)" should be submitted to the environmental protection department.
