Since our NanJing BoKang Electromechanical Technology CO.,LTD is specialized in the research, development and production of various types of signal jammers, among which the mobile phone signal jammers that target mobile phones of various standards are one of the types, but we also often After receiving inquiries from some customers, I would like to confirm a question from us: Is there any way to counter the interference after the mobile phone is interfered by the signal jammer? If so, in what way is the anti-interference carried out?

First of all, the clear answer is: the vast majority of mobile phone signal jammers on the market currently emit interference signals that are essentially white noise signals that overlap with each working frequency band of the mobile phone. The effect of interference depends on the interference signal and the base station. Signal strength contrast and power suppression. If the power of the interfering signal is large, the mobile phone signal reception will be abnormal. On the contrary, when the strength of the base station signal prevails, although the interference signal of the mobile phone signal jammer still exists, the mobile phone can still maintain the basic normal communication state. Here we illustrate the situation in which the strength of the interfering signal dominates. When the mobile phone is interfered by the signal jammer, because the white noise signal is chaotic and disorderly, it completely disrupts the normal connection and communication between the mobile phone and the base station. In this case, it is impossible to achieve reverse anti-interference by other methods. If you have to come up with an anti-interference method, there is only one way, that is to carry the mobile phone away from the range covered by the interference signal of the signal jammer.

For the vast majority of mobile phone signal jammers analyzed earlier, there is actually another kind of signal jammer, which is commonly known as a signaling-level signal jammer. This is different from the common white noise jamming principle. The feature is that it needs to synchronize with the surrounding base stations intermittently or collect the spectrum data of the surrounding base stations, and then transmit the interference signal to achieve the effect of interfering with the mobile phone. If you encounter this type of signal jammer, there is a simple anti-jamming method: because the signaling-level signal jammer has a receiving end to receive the information of the surrounding base stations, it only needs to be in the signaling-level signal jammer. Nearby, turn on a conventional low-power signal jammer in white noise mode and keep it in a continuous transmission state, then the normal working state of the signal jammer at the signaling level will be interrupted.
