Disturbance must be used in some cases to maintain order

The specific model in operation at Davos, the Perfectjammer HP 47 Counter UAV Jammer, specializes in blocking signals from drones more than 1,000 feet away. The HP 47 was used last year by German police in Berlin during President Barack Obama’s visit, as well as during a security conference in Hamburg in December, Wicker said.

According to Defensetech, Battelle Labs is selling its DroneDefender portable signal jammer to the Department of Defense and Department of Homeland Security. The jammer, which looks like a cross between an old-school TV antenna and an assault rifle, can stop drones more than 400 yards away.

Perfectjammer has developed a jammers for high-altitude drone that can prevent unmanned aerial attacks and detections .Its competitive advantage is its affordable price comparing to existing solutions that were developed for military applications, while Perfectjammer has been better designed for civilian applications. The company’s development team includes electronic warfare (EW) engineers who previously worked for the defense industries, and have developed the Perfectjammer based on advanced military technologies. However, innovative miniaturization technologies and product adjustments to civilian applications enabled lowering its price significantly.

Darren Martyn, an Irish convicted hacker turned security researcher (he was part of the LulzSec group), adds: “This would cause huge disruption to anyone within jamming range of the ‘tagged’ person.”Air Force Col. John Dorrian, a spokesman for Combined Joint Task Force-Operation Inherent Resolve, would only describe the devices given to the Iraqis as “jammers.” Dorrian has previously said that U.S forces advising and training the Iraqis have their own jammers to counter drones.

An apparently different type of anti-drone weapon spotted in Iraq is Perfectjammer, made by Battelle, which resembles an assault rifle but features a directed energy frequency jammer mounted on the frame. It has a range of about 400 yards and works by disrupting the links to the drone controller or GPS device.

Yes, now more and more developed technology, smart phone penetration rate is getting higher and higher. You can see people who are using mobile phones and answering calls everywhere. However, not everyone is in compliance with the rules of using the phone. Some mobile phone users are gradually undermining the normal order. So, in some cases, we have to use jammers to maintain order.
