Drone signal jammer is a device used to block wireless communication signals of drones, aiming to limit illegal flight or mission operations of drones in a specific area. cell phone jammer With the advancement of science and technology, drones have gradually become part of our daily lives, but the problems of privacy invasion and airspace interference that come with it have become increasingly prominent. GPS jammer In order to solve these problems, drone signal jammers have emerged. This article will introduce its working principle and how to effectively block drone communication signals.Wifi jammer

　　Drone communication principle

　　To understand the role of drone signal jammers, you first need to understand how drones communicate.signal jammer Drones mainly rely on radio waves for data transmission, usually using the 2.4GHz and 5.8GHz frequency bands. These frequency bands are widely used around the world, so drone signal jammers must cover these two frequency bands to effectively interfere with most drones.

　　Working principle of drone signal jammer

　　The main working mechanism of drone signal jammers includes two aspects: one is to block the communication between the drone and the remote control, and the other is to block the communication between the drone and the ground control station. By emitting radio waves of a specific frequency, the jammer can effectively cut off the communication link of the drone, making it unable to operate normally.

　　1. Blocking the communication between the drone and the remote control

　　When operating a drone, the remote control sends control instructions to the drone via radio signals. These signals are usually transmitted using pulse code modulation (PPM) or frequency modulation (FM). The drone signal jammer interferes with the signal received by the drone by emitting radio waves of the same or similar frequency, phase and modulation method, making it unable to correctly interpret the instructions issued by the remote control. Even if the remote control is working properly, the drone cannot respond to the operation command.

　　2. Blocking the communication between the drone and the ground control station

　　In addition to the remote control, the drone can also be remotely operated through the ground control station. The ground control station establishes a data link with the drone to transmit information such as instructions and images. The drone signal jammer can also interfere with these data links by emitting specific radio waves, preventing normal communication, causing the drone to be unable to receive any instructions and stop the mission execution.
