All objects in nature, as long as the temperature is above absolute zero, will continuously transmit heat outward in the form of electromagnetic waves. This way of transmitting energy is called radiation. Any electrical equipment will have electromagnetic radiation, therefore, wireless routers will definitely have radiation. Single serial port server "The signal emitted by the 4G industrial router is the same as the light in nature. In a broad sense, it is a kind of radiation, but this radiation will not cause harm to the human body when used within a reasonable range."
Wireless routers will generate electromagnetic radiation to their surroundings during operation. The operating frequency of wireless routers is 2.4 MHz, and the transmitted power varies according to different places of use. The electromagnetic radiation generated by a wireless router during operation depends on its transmit power.
For small wireless routers commonly used in offices, the electromagnetic radiation power density value is between 1.1 microwatts/square centimeter and 13 microwatts/square centimeter when it is close to the antenna of the router. The power density value is between 0.024 microwatts/square centimeter and 0.14 microwatts/square centimeter, and the electromagnetic radiation power density value is already lower than the lower limit of conventional electromagnetic radiation testing instruments when it is 1 meter away from the router.
Non-governmental environmental protection organizations have also conducted tests. At a distance of 1 cm next to the wireless router antenna, the measured power density is 9.1 microwatts/square centimeter, which is also less than the 40 microwatts/square meter stipulated in my country's "Electromagnetic Radiation Protection Regulations". cm limit.
Generally, the electromagnetic radiation level around a small wireless router is the highest at the position AC-DC single channel close to the antenna of the wireless router, but it is also lower than the limit specified by the national standard. As the distance from the wireless router increases, its radiation field strength shows a rapid attenuation state, and it has basically been reduced to a level that will not have any impact on the human body beyond 1 meter. "So, its impact on the human body is basically negligible."
