What is the principle of mobile phone signal jammer? Why can the signal be blocked?

When the mobile phone is in normal communication, it will convert all the operations on the mobile phone into data, and then transmit the data through electromagnetic waves.

Electromagnetic waves associate mobile phones with signal base stations within a certain frequency range, and then complete data conversion and transmission through specific baud rates and modulation methods. .

And the coverage of the signal base station is limited, and if you happen to be on the edge of the coverage, there will be a situation where the signal is weakened.

Cell phone signal jammer generally block the connection between the electromagnetic waves emitted by the mobile phone and the signal base station. Interrupted communication between the mobile phone and the signal base station.

Jammers emit random static or noise over a wide range of frequencies, making it impossible for devices close to the jammer to connect to the base station, such as a sports car engine cranking and you're on the phone on the phone. The local noise is strong enough to make the device unable to connect normally, effectively blocking the normal operation of the mobile phone signal.

The signal jammer also emits electromagnetic interference signals. The carrier frequency of this signal is the same as the carrier frequency of the base station signal. Therefore, it can form garbled interference when the mobile phone receives the signal. The mobile phone cannot detect which are normal data sent by the base station and which are It is an interference signal, effectively blocking the normal operation of the mobile phone signal.
