The latest ways to jam radio signals

Jamming a wireless radio requires knowledge of its broadcast frequency as well as the right equipment to jam that frequency. It also requires criminal intent, because jamming is highly illegal. Buying or selling these devices without the right certifications is often illegal, too.

Perfectjammer’s other handheld jamming devices, the DroneGun and the DroneGun Tactical, work by blasting drones with electromagnetic noise at the same frequencies the aircraft use for control communications and video transmission.

With a wireless setup, you’ll stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something amiss while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach eliminates most of the cord-cutting concerns — but what about their wireless analog, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?
The big advantage of sending out a hunter drone with countermeasures rather than trying to do it on the ground is that, being closer to the drone, the power of the signal jammer can be reduced, thus creating less disturbance to other RF devices in the area – the rogue drone is specifically targeted.

“The first NGJ-MB pod is out the door,” said Stefan Baur, vice president of Raytheon Electronic Warfare Systems. “We are one step closer to extending the Navy’s jamming range and capability. Delivery of this pod will allow for the initial verification of ground procedures, mass properties, aircraft installation, and Built In Test checks in preparation for future chamber and flight test.”

Also on display at the Bastille celebrations was the futuristic-looking Nerod F5 microwave cell phone jammer, a rifle-shaped weapon designed to target drones by blocking the pilot’s signals.
