How to make the mobile phone signal jammer fail?

  • 2022-09-23

If you want to make the mobile phone signal jammer lose its interference effect on the mobile phone signal, you must first understand the working principle of the jammer, that is, the signal emitted by the jammer, the white noise interference signal with the same frequency as the signal used by the mobile phone. When the intensity of the interference signal emitted by the jammer is stronger than that of the mobile phone signal transmitted by the on-site base station, the mobile phone signal will be completely submerged by the signal emitted by the jammer, Then the mobile phone cannot search the service signal of the base station, and the mobile phone will show no signal, limited service and other phenomena.


So, how can we make the jammer lose its interference effect on the mobile phone without destroying the jammer? Here are two methods you can try.

First, reduce the power supply voltage of the mobile phone signal jammer. Generally, the jammer needs to be connected to 220V AC mains power, and then output DC power through the power adapter or switching power supply. A better quality power adapter and switching power supply will use a wide voltage AC power supply, and the voltage range of AC voltage is 85-265V. If you want the jammer to fail, let the power supply voltage drop below 85V, so that the switching power supply of the jammer cannot work properly. At this time, you can make the jammer unable to work properly, and then you will lose the interference effect on the mobile phone. Of course, this method is generally not easy to implement, which requires professionals to operate, and attention should be paid to safety when operating.

Second, enhance the signal strength of the mobile phone on the site of use, so that the signal strength of the mobile phone on the site of use is higher than the signal strength transmitted by the mobile phone signal jammer. The signal transmitted by the jammer cannot cover the mobile phone signal on the site of use, so the jammer will lose its interference effect on the mobile phone. This method requires the help of a mobile phone signal amplifier, which requires a receiving antenna, and the location of the receiving antenna, You must be far away from the signal coverage range transmitted by the jammer to receive the mobile phone signal normally, otherwise you will still be interfered by the jammer. Then place the transmitting antenna of the mobile phone amplifier on the site where the jammer is used.
