In recent years, more and more school units have used mobile phone signal jammers. Many people have a strong understanding of signal jammers, but there are still more questions during use, such as the interference methods of signal blockers. What is it? And how to achieve signal interference, will it cause harm to the human body and other issues?

When using a signal shielding device, the mobile phone signal jammer emits electromagnetic interference at the same frequency as that received by the mobile phone. It only blocks the connection between the mobile phone and the base station and keeps the mobile phone in a poor signal search state. It will never cause any harm to the mobile phone. Damage! When the cell phone signal blocker is turned on, the cell phone must not exchange connections with external radio waves. Therefore, the phone lacks a data signal and will search for the signal from beginning to end, thus reducing energy consumption.

The principle of the cell phone jammer: the mobile phone and the base station are connected through radio waves. During the working process, the mobile phone signal jammer is a self-confident scanner from the low-end frequency to the high-end frequency of the channel. The scanning speed can be used when the mobile phone receives messages. There are errors in the format signal, and the mobile phone cannot detect the stable data received from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone presents problems such as network search, poor signal, and no service system.

After the signal jammer is removed, the phone will recover after a while. If the mobile phone signal jammer is turned on, be sure to turn off the mobile phone!
