Short of shooting down a drone with physical projectiles, the only anti-drone technology in existence is what is commonly known as a “drone jammer.”
What is a drone jammer?
Drone jammers are modern devices that are designed to stop drone threats from entering controlled airspace and critical areas such as airports, prisons and industrial facilities, detention centers, military playgrounds, and other departments.
How do drone jammers work?
Jammers work by blasting electromagnetic noise at the radio frequencies that drones use for communication, navigation, or video transmission. They disrupt the communication or navigation signals between a drone and its operator, effectively neutralizing the drone. In most cases, this will result in the drone activating its Return to Home function, through which the drone pilot can be identified.
Types of drone blockers
- Portable drone jammers
- Stationary/Fixed Jammers
- Directional vs. Omnidirectional Jammers

2. Non-portable drone jammer
Types of signal target
The drone jammers aim to target the radio frequencies (RF) or GPS signals that the drone relies on to function. RF jamming for drones uses radio frequency signals to block the communication between a drone and its operator or other systems like GPS. This causes the drone to lose control or stop working. The jammer targets specific frequencies for drones' control, communication, and navigation.
1. Control Signals: Similar to telemetry signals.
These are RF signals sent by the operator to control the drone's movements.
2. Communication Signals:
-
Date Transmission: This type involves sending information between the drone and its operator, as well as between the drone and its onboard systems. This includes not just control signals but also video feeds, telemetry, GPS data, and other types of information.
-
Video Transmission: Many drones send live video feeds back to the operator via RF.
-
Image Transmission: It refers to the process of sending image data—typically captured by the drone's onboard camera—from the drone to the operator or a remote system for viewing, storage, or analysis
3. Navigation Signals:
-
GPS Jamming: By broadcasting signals on GPS frequencies, the jammer blocks the drone’s ability to receive satellite navigation data.
-
Satellite Signals: These refer to the radio frequency (RF) signals used for communication between a drone and satellites in orbit.
Alternatives to Drone Jammers
1. Drone detection system
-
Radar-based systems: They can track the location, altitude, and speed of a drone. And provide early warning of a drone entering a restricted area.
-
RF detection systems: They can detect the radio frequency emitted by drones. They can identify both control and video transmission signals, allowing authorities to pinpoint the location of the drone.
-
Acoustic Sensors: These systems use microphones to detect the sound of drone motors or propellers. They are useful in environments where visual or radar detection might be limited.
-
Optical and Infrared Cameras: Cameras equipped with infrared sensors can detect drones based on their heat signature or movement. These systems can identify drones even at night or in low visibility conditions.
2. Physical ways
-
Netting and Fencing: Installing large physical barriers, such as nets or fences around sensitive areas, can physically prevent drones from entering.
-
Geofencing: A geofence is a virtual boundary created around a restricted area. Many drones come with built-in geofencing capabilities that prevent them from entering certain zones.
-
Use harpoons or other physical projectiles to capture or disable drones mid-flight.
-
Trained bald eagles.
-
Jet Skis
3. Software
-
Drone-identified apps: These apps use ADS-B (Automatic Dependent Surveillance-Broadcast) to identify the make, model, and location of drones flying in a particular area.
-
UAV (Unmanned Aerial Vehicle) Detection Software: Some software solutions are designed to detect drones by analyzing radio signals, video streams, or other communication channels used by the drone.

Safety and Legal Considerations
Future of drone jammers
1. Less collateral inference: The directional drone jammers will aim at targets more precisely and reduce the impact on other devices.
2. Ai-powered detection: The drone jammer with AI can defend against drones automatically.
3. Legally Compliant Systems: The users can deploy drone jammers in law enforcement and security agencies legally.
