The principle of the wifi jammer is to emit electromagnetic interference signals of high frequency and full band, turning all the signals into clutter, and if you can find a network, you can connect.
The wifi signal jammer will not affect the human body. The working principle of the wifi jammer device is to scan from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the received message signal of the mobile phone. The mobile phone cannot detect the normal data sent from the base station so the mobile phone cannot establish a connection with the base station, so as to achieve the purpose of shielding the mobile phone signal. No service system, etc
The power of the wifi scrambler is generally not too large, basically, it is tens of watts, the indoor use generally does not exceed 100W, and the radiation amount is basically negligible. So it will not affect the human body.
