Is wifi harmful to human health? Is wifi harmful to human health?

1, WiFi is actually a small LAN, mainly for data transmission. As a wireless device, WiFi has a transmitter, which does produce electromagnetic radiation around it. There is no harm to people's health at present.

2. The working power of the most common wireless router is 30-500 MW, which is smaller than that of ordinary mobile phones (about 125 MW-2 W). Compared with mobile phones, WiFi devices such as wireless routers are far away from users, which makes the power density of their radiation received by people much smaller.

The intensity of radiation is inversely proportional to the distance. At this time, the radiation value is only one tenth or even one tenth of the national limit. In fact, there is no essential difference between wifi and mobile phone signals, both belong to microwave, which is generally located in the frequency band of 800 MHz-1900 MHz.
