The use of drones raises concerns among citizens

　　Drones take up commercial airspace, yet are small enough to buzz past us while we are standing in our own backyards and driveways.Those concerns lie with privacy and public nuisance.

　　From catastrophe response to news-gathering to construction-site monitoring, commercial drones represent one of the fastest-growing sectors in technology.

　　There are a wide variety of UAV shapes, sizes, configurations, and characteristics. Commercial or civilian drones are of special concern. Most drones have high-resolution cameras that can invade your privacy. They can capture images of you and your personal property.

　　People also use drones to smuggle drugs. Or they use them to crash into buildings or act as a remote “peeping Tom.” They can cause harm when carrying a payload of explosives or artillery.

　　Jammers gps are also called signal blockers. They are devices that block radio communications signals. A pilot on the ground remote-controls an Unmanned Aerial Vehicles. Therefore, blocking the radio signal renders a UAV useless. The drone will either fall to the ground or land, depending on its programming.

　　When locked onto a drone, the drone jammer disrupts the GPS and radio signals guiding it. It is effective from up to 400 meters away. This makes it a long-range weapon.

　　The cheaper, less complex drones will simply fall to the ground when hit by the jammer.

　　Others will revert to a fallback mode, such as return home or hover to the ground. The advantage is that no collateral damage results from the drone falling from the sky. Further, the jammer would not destroy the drone itself.
