For us, Nanjing Bokang Electromechanical Technology Co., Ltd. is a professional research and development and production of various types of mobile phone signal jammers. Among them, mobile phone signal jammers that use various types of mobile phones as interference targets are one of the types, but we also I often receive inquiries from some customers and want to confirm a question from us: Is there any way to counter the interference after the mobile phone is interfered by the cell phone signal jammer? If so, what method is used for anti-jamming?

First of all, the answer can be relatively clear: most of the mobile phone signal jammers currently on the market, the interference signal emitted by them is essentially a white noise signal overlapping with each working frequency band of the mobile phone, and 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. Conversely, when the strength of the base station signal prevails, although the interference signal of the signal jammer still exists, the mobile phone can still maintain a basic normal communication state. Here we use the situation that the strength of the interference signal dominates to illustrate that when the mobile phone is interfered by the mobile phone signal jammer, because the white noise signal is disorderly and disorderly, it completely disrupts the normal connection and communication between the mobile phone and the base station, so In this case, it is impossible to achieve reverse anti-jamming by other methods. If you have to come up with an anti-interference method, there is only one way, which is to take the mobile phone away from the area covered by the interference signal of the mobile phone signal jammer.

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