Introduction to the principle of mobile phone signal jammer

source:Industry News release time:2020-12-25 Article author:sznbone Popular:Prison Jamming system

  The principle of the mobile phone signal jammer is: within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. Aiming at the above-mentioned communication principle, the jammer scans from the low end frequency of the forward channel to the high end at a certain speed during the working process.

  This scanning speed can constitute garbled interference in the message signal received by the mobile phone, and 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 mobile phone is manifested as a search network, no signal, and invalid labor system. Eventually, the mobile phone has no signal and cannot receive text messages or calls.

  Wireless communication is the use of electromagnetic waves to stop communication. The functional characteristics of electromagnetic waves are determined by its frequency. Our mobile phones must emit electromagnetic waves that meet the requirements to connect to our communication carrier base stations. The basic principle of mobile phone interference equipment is to transmit the same radio frequency as the mobile phone. Because the frequency is the same, the mobile phone can't tell which signal is the base station signal on track, thus completing the "interference". So how is this kind of multi-network interference accomplished? it's actually really easy. It is to repeatedly play the interference bands corresponding to the three signals in a loop, and cover the three bands at once, and the distance of this loop is so small that the mobile phone can only sit down when there is basically no speech.

  The main principles of signal shielding and signal jammers are currently in the frequency band used by the mobile phone, which emits great noise and disturbs the reception and transmission of the normal signal of the mobile phone. This small object is not only used to avoid cheating during exams, it is also used politically and militaryly to avoid fear attacks.
