A 5g signal jammer is a device that can block mobile phone signals. Generally speaking, there are many signal shields in the examination room, and some government agencies and confidentiality offices also use signal screens.
The purpose of a jammer is to prevent unscrupulous people from using cell phone recordings to leak certain secrets.
Interference means that the mobile phone signal cannot detect normal data sent from the base station, making it impossible for the mobile phone to establish a connection with the base station, thus achieving the purpose of blocking the mobile phone signal. The mobile phone displays no signal and no service.
The working principle of the 5g signal jammer is to scan the previous low-end frequency to the high-end channel at a certain speed. This scanning speed can create garbled characters in the signal received by the phone.

After the 5G signal is blocked, the mobile phone may display the signal, but it can no longer make calls or surf the Internet. The confidentiality of examination rooms, conference rooms and other places can be ensured by turning off the signal screen.
It can be used normally after shielding. The cell phone signal jammer will not cause interference to other electronic devices.
