Signal jammers sometimes fail to block signals when working
When the signal shielding device is running, there are two possibilities if the mobile phone indicates that there is a signal:
First, the mobile phone can be connected. If the mobile phone can access, it means that the shielded area has not been properly shielded and there are loopholes. This also means that your current mobile phone shielding product cannot meet your local shielding requirements;
The second is that the mobile phone cannot be connected temporarily. If this is the case, it means that the mobile phone is at critical damping. This situation generally occurs on mobile phones with strong anti-interference ability and high sensitivity.
Detailed introduction to the basic principles of signal jammer
The principle of the signal jammer is as follows: within a certain operating frequency range, mobile phones and communication base stations are connected using electromagnetic waves, and information and sound effects are transmitted with a certain serial port baud rate and deployment method.
Regarding the basic communication principle, the signal jammer for phone passes the low-end power of the wireless channel to the high-end scanner at a certain rate during the operation process. This scanner speed can cause errors in the packet format signals received by the mobile phone. The mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The main symptoms of mobile phones include searching the network, poor signal, and no service system.
