Common types of small drones, because they do not need to fly too high from the ground, have a small appearance, and can fly fast or slow, so "low, slow, and small" are often used to refer to small drones. man-machine. Nowadays, under the marketization of such drones, the process of selling and buying is quite simple, and almost anyone can buy commercial versions of small drones without restrictions. Such extensive use will inevitably bring certain security risks, so various confidential units and special departments have begun to deploy drone jammer systems. Drones are like offensive "spears" that want to fly at will, and the drone jammer system is a "shield" for defense, it will do everything it can to prevent drones from flying indiscriminately , The means of prevention is not only to drive away, but also to effectively attack or force landing until it is captured. So the question is, is it possible for common drones to break through the defense of the drone jammer system?

At present, for all commercial drones obtained through conventional purchase channels, the remote control channel, image transmission frequency (or channel), satellite navigation positioning channel, etc. used are all frequency bands or channels of international general standards. And as long as it is a regular drone manufacturer, it will be assembled and produced according to uniform standards. Correspondingly, manufacturers of drone jammer systems only need to configure the same corresponding frequency bands to form effective interference and suppression, which is enough to ensure that those drones cannot break through the defense.

So if someone modifies these drones privately, can they break through the defense of the drone jammer system? It depends on how the modification is carried out, and it also depends on the technical ability and actual hands-on ability of the person who does the modification. If the person who modifies has a strong theoretical foundation of radio communication technology, this may involve the modification of the communication channel of the drone. However, if the wireless communication module is modified, it is also necessary to purchase related electronic components or radio frequency modules. In fact, these outsourced devices still cannot bypass the frequency range of the international general standard. The final situation is actually: the so-called private modification is only a small change, and it cannot completely break through the defense range of the drone jammer system.

Of course, the drone jammer system itself will also fully take into account some private modification factors, so the various interference frequencies and interference frequency bands it has built-in have enough redundant bandwidth, even if there are individual frequency bands in common drones. There are changes, but the drone jammer system will still be unable to fly normally due to the multi-band and high-power interference of the drone jammer system.
