After some units install the signal jammer, the mobile phone signal and WIFI signal will be interfered, which will cause the mobile phone to temporarily lose the function of answering and making calls, and cannot browse websites, watch videos, play online games, etc. normally. Therefore, some staff from such units often call us to ask: Once the signal jammer is turned on and working, what can be done to prevent interference?

From the conventional way of thinking, even if the interference signal is transmitted through the signal jammer, it can play the role of signal interference, then think about the problem in reverse: whether there should be a way, or whether there is an electronic product, Can the anti-jamming signal be used to counteract the jamming signal of the signal jammer? Some customers even ask: Is there an electronic device that can decipher the interference signal of the signal jammer, so as to achieve the purpose of anti-jamming?

However, the above can only be regarded as personal conjectures, and the actual results can never be achieved through conjectures. The interference principle of the signal jammer is very simple to put it bluntly. It imposes a strong interference signal on all communication frequency bands of the mobile phone. This interference signal is chaotic white noise. From the analysis of technical principles, it is precisely because Interference signals are disordered and irregular, so naturally there is no targeted way to decipher them. Then analyze it from the perspective of the so-called anti-jamming signal: once the jamming signal of the signal jammer is emitted and spreads around, this process is a process of natural attenuation as the propagation distance increases, and there is no imposition of a Anti-interference signals can play a role in suppression or elimination. So this approach doesn't work either.

According to all the technical capabilities or means that can be imagined at present, we can only say: Once the signal jammer is turned on and working, there is indeed no way to achieve anti-jamming. For problems that cannot be achieved by technical means, we can only rely on some simple and brutal means, such as directly powering off the signal jammer or using a metal cover to completely buckle it.
