Wireless routers will generate electromagnetic radiation

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.Industrial Router/Gateway Any electrical equipment will have electromagnetic radiation, therefore, wireless routers will definitely have radiation. "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 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."

The results of testing data by the authoritative security testing department show that the electromagnetic radiation generated by the detected wireless industrial router is stable within 4mG (milligauss), and the occasional high value may be interference, and the radiation is within 2mG after leaving the router for 50cm. In the working state, there was a slight increase in the radiation when the computer was connected and disconnected, but it was not statistically significant. Compared with electromagnetic radiation such as electromagnetic cookers, microwave ovens, and mobile phones, the electromagnetic radiation of wireless routers is still relatively small. When the microwave oven is working, the radiation reaches 130-360mG, and it can only be reduced to 2mG 1.5 meters away. When the mobile phone is in standby, the electromagnetic radiation is only 2mG, but when calling someone else, the moment the mobile phone is dialed out, the radiation reaches 50-100mG, and it will return to normal after three or four seconds.

The above report on the radiation intensity of wireless industrial routers, I believe that many friends have let go of the big stone in their hearts. Remote IO module We usually use wireless routers at a distance of more than 1 meter, so the "radiation" understood by users can be completely ignored, and we are still testing 802.11n. Products, mainstream 54M products will be lower. Finally, to sum up, if you can accept the "radiation" of mobile phones, then WIFI products have little impact on your health, and you can use them with peace of mind.
