At night school dormitory just open jammer, body are you OK?
The jammer will not affect the human body. The working principle of the signal jammer gps 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 will cause garbled interference in the SMS signal received by the mobile phone. The mobile phone cannot detect the normal data sent by the base station, so that the mobile phone cannot establish a connection with the base station, so as to achieve the purpose of shielding the mobile phone signal. No server system etc.
Generally, the power of the shielding cover is not too large, it is basically dozens of watts, and the indoor use generally does not exceed 100W, and the radiation amount is basically negligible. So it will not affect the human body.
