Drone jammers destroy drone flight by transmitting radio wave noise at radio frequencies, blocking effective communication between the drone and its controller. Mainly unassigned public frequencies, namely 2.4Ghz and 5.8Ghz, also known as "RF interference". This means that drone jammers do not affect the normal radio frequency range of aircraft, mobile phones, etc. that are normally driven.
In addition to disturbing the "common frequency", the UAV jammer can also partially interfere with the GPS band. When the drone is hit by the signal emitted by the jammer, the unmanned machine returns to the origin, and the controller of the drone can be monitored at this time. Sometimes the uavs would hover in the air or land vertically.
The signal shielding range of drones is generally between a few hundred to thousands kilometers, so a drone jamming device can withstand drones several kilometers away. In the fight against drones, the use of drone jammers is safer than other schemes and does not destroy drones and evidence. Other programs, such as dropping drones, generally cause damage to the drone and may even lead to allegations of damage to private property.
In the military field, drone jammer have a greater role. When a drone carries a man-made bomb or other dangerous item, using a jammer is the safest method, because a drone jammer would force the drone to return to the origin, and shooting the drone in other ways may cause the bomb to explode. There are even casualties or deaths.
Today, drones are common in real life, such as for personal travel aerial photography, children's entertainment tools, etc. However, drones have many illegal uses, such as carrying bombs, illegal surveillance, smuggling of prohibited items, sneak shots, interference Airport flight flights and more.
The use of drone jammers is necessary. In the past, terrorist drone incidents have occurred frequently: an ISIS drone with explosives killed two Peshmerga fighters and wounded Two French soldiers and used for battlefield surveillance. Air Force Minister Deborah Lee James said: Some small drones, if placed with small explosives on them, could cause heavy casualties.
This portable drone jammer gun uses a gun-shaped design to interfere with the drone's in-use frequency band, causing the drone's remote control to fail, and the captured images and video cannot be returned, forcing the drone to hover and land, cutting off The connection between the drone and the remote control and the ground station is particularly suitable for military areas such as prisons, drug rehabilitation centers, secret areas, and military units.
