1) Handheld Jammers:
Handhed jammers block wireless communications such as GPS, WiFI, Bluetooth and radio frequency signals.
-
Effective coverage: Can reach up 2km (Handle different drone model and effectively protect designated airspace).
-
Capable of jamming UAV flight control bands and video transmission frequencies;
-
Adopt UHF broadband seamless interference technology.
-
The built-in battery can operate over one hour on battery power alone and charge the battery in four hours.
Features:
Stationary jammers with higher output power, permanently installed in key locations such as government buildings and airports. Their robust design allows for broader coverage and reliable performance in critical areas.
Effectiveness:
These jammers provide continuous, reliable protection against drone intrusions. With the ability to jam multiple frequencies simultaneously, stationary jammers ensure comprehensive security. They are available in power options ranging from 40W to 400W, with coverage distances from 100m over 1 kilometer, making them highly effective for large areas.
3) Vehicle-Mounted Jammers:
Features:
Vehicle-mounted jammers are mobile systems designed to cover large areas, making them ideal for dynamic security applications. These systems provide a flexible solution for protecting convoys, large events, or mobile operations.
Effectiveness:
With enhanced power and mobility, vehicle-mounted jammers can protect against drone threats over a wide area, making them essential for real-time, adaptable security operations.
4) Portable Drone Jammers (Backpack Jammers):
Features:
Portable drone jammers, including backpack models, combine the convenience of portability with the power and coverage of vehicle-mounted systems. While not all fixed jammers are portable, these models offer a practical solution for on-the-go security needs.
Effectiveness:
Portable jammers offer more power and greater coverage than standard handheld units, making them ideal for special events, tactical operations, or military security. They provide a flexible option for targeted drone disruption without compromising on performance.
2. Classified by interference mode
| Types of Jammers | Modes of Interference | Characteristics |
|---|---|---|
| Active Jammer | Continuously transmits jamming signals. | Disrupts navigation and communication signals (RF), high power output, and can interfere with other systems. |
| Passive Jammer | Detects and manipulates signals without transmitting interference. | Steadier, power-efficient, only affects drone communications without causing widespread disruption. |
| Integrated Jammer | Combines active and passive interference. | Uses both signal generation and interception techniques, effective against a wider range of drone signals. |
1) Active Jammers
Active jammers emit powerful electromagnetic signals that disrupt drone communications. These jammers operate at frequencies used by drones, such as 2.4 GHz, 5.8 GHz (for communication), and 1.57 GHz (for GPS navigation), effectively overpowering legitimate signals to prevent stable communication between the drone and its controller or GPS system.
-
RF Jammers: These jammers emit strong signals on frequencies like 2.4 GHz and 5.8 GHz, which are commonly used by drones.
-
GPS Jammers: Targeting GPS frequencies (e.g., 1.575 GHz), these jammers prevent drones from utilizing GPS signals.
-
Broadband Jammers: These devices can block a wide range of frequencies, including both communication and GPS signals, commonly used by drones.
-
Directional Jammers: These jammers focus the signal in a specific direction, allowing precise targeting of drones while minimizing disruption to surrounding areas.
-
Omnidirectional Jammers: These jammers emit signals in all directions, providing 360-degree coverage to target drones without affecting nearby areas.
2) Passive Jammers
Unlike active jammers, passive jammers do not generate jamming signals. Instead, they detect the signals transmitted by the drone and reflect or absorb them in a way that prevents communication with its GPS or remote control. These jammers work by disrupting the drone’s ability to maintain stable control or navigation, without emitting their own jamming signals.
3) Counter-Drone Integrated Systems
Counter-drone integrated systems combine both active and passive jamming techniques to detect, track, and neutralize unauthorized drones in airspace. These advanced systems are designed to provide comprehensive protection by using a combination of methods to interfere with drone operations and ensure airspace security.
In the last blog post, we will continue to delve innto the Anti drone systems.
