The US government has spent 17 billion US dollars to purchase 50,000 jammer units, including "Warlock Green", "Warlock Red", "Warlock Duke", "Acorn" and other names. But at the beginning of the war, a game of cat and mouse took place between the radio frequency interceptor and the improvised explosive device, and the interceptor was far behind the cat and the mouse. They are too slow to adapt well and can only protect a few yards. And from time to time, two signal jammer interfere with each other and cancel each other out.
A new generation of jammers has also been introduced, which can cover a wide frequency range and perform specific "trigger" interference, which means "Duke did not confuse the receiver with a modified version of its own signal. As the interference improves, Fooling on very specific equipment. "As interference improves, Iraqi insurgents have largely abandoned the use of improvised explosive devices, and the death toll caused by improvised explosive devices has decreased.
Long-range interference uses radio frequency control technology to stop drones in the air to help establish the security of military installations or colonies. The weapon operates on the standard GPS and ISM radio frequency bands (2.4Ghz 5.8Ghz Wi-Fi), which can interfere with commercial drone signals. The gun can operate in a large frequency range, which can detect and shoot down drones from a long distance.
Google conducted a quick search and found several companies claiming to sell equipment that can block drone control signals, which may cause the unwanted quadcopter to crash or return to its origin, depending on the manufacturer.
Do you have a drone and want to play? This technology uses wifi interference, which will interfere with the connection between the drone and the controller. This can be very effective when dismantling drones that use Wi-Fi as a communication method.
