Two companies have developed two systems to neutralize quadcopters: DroneGun disrupts frequencies, while SkyWall100 throws a wraparound net into the air
Drones have become massively popular in recent years, mainly due to the ease with which they can be guided. Moreover, it only takes a few hundred euros to buy a quadricopter online with good range and reliability.
This proliferation, however, can pose a danger to people's safety. Starting with privacy, which is easily violated by a drone. Some countries, for example, have taken action to protect the privacy of citizens, blocking by law the use of drones in public, as in the case of Sweden. In other situations, these technological tools pose even greater threats. Drones, unfortunately, can be equipped with weapons and explosives and used by criminals and terrorists. To cope with this problem, some companies have developed advanced anti-drone systems, capable of neutralizing quadcopters.

Among the solutions made available by technology to safely shoot down drones, we find DroneGun and SkyWall100. The first one, which was made by the company DroneShield, is a device that nullifies the signals of the aircraft - including the GPS - using a jammer, that is, a frequency jammer that blocks the communication between the drone and its pilot. DroneGun does not destroy the drone, but forces it to land or return to where it started. One of the most important features of the anti-drone system is given by the range of coverage: DroneGun, in fact, can block drones flying up to 2 kilometers away. In addition, the tool can also be used to pinpoint the location of the pilot.

SkyWall100 is reminiscent of a traditional weapon in some ways. Unlike DroneGun, the system developed by British company OpenWorks Engineering uses a special projectile to neutralize the threat coming from above. Drones are, in fact, hit by an object that sets off a net that wraps around and shoots down the quadcopter. Everything depends on the SmartScope, a digital telescope that calculates the launch angle and the speed needed to reach the target. Once the target is located, the SmartScope starts beeping and flashing green. At this point, all the pilot has to do is pull the trigger.
