What methods do drone jammer rely on to combat drones?

In recent years, as drones have gradually entered our daily life, they have performed prominently in environmental monitoring, express logistics, power inspection, disaster rescue, and aerial photography. Although the drone industry has developed rapidly in the past two years and drone technology is very mature, there is still a problem worth thinking about, that is, how to prevent the occurrence of security incidents caused by drones. This requires professional drone jammer countermeasures to monitor and jam drones. So what method does this countermeasure device rely on to restrain the drone?
In some places, by developing application software, using positioning data to intervene drones, and by locating "no-fly zones" in real time, they provide drone users with flight prevention to avoid accidental entry. Now, the management regulations for drones are gradually improving, especially the anti-drone jammer technology is gradually mature. Strive for as many drone flight rights as possible to promote the healthy development of the drone industry.

Under the condition of ensuring the safety of low-altitude areas, some areas use drones to interfere with drone signal jammer equipment to reduce the occurrence of "black flying" as much as possible. The drone frequency jammer device interferes with the application function on the UAV, making the control system on the UAV ineffective, and the operator cannot control it, which indirectly causes the UAV to stop flying.
