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 LoRa wirelss modem 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 test results of 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 others, 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. 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, Industrial Router/Gateway 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.
