Drone jammer modules generally include the following categories:

RF Jamming Modules:
These modules transmit radio frequency signals at specific bands to interfere with a drone’s wireless communications, such as control links and video transmission signals, causing loss of control or signal interruption.

Electro-Optical Identification Modules:
Equipped with optical or infrared sensors, these modules are used for real-time detection and identification of drones. Through image processing technologies, they can identify drone types, flight direction, speed, and other key characteristics.

Radar Detection Modules:
Radar systems are used to detect and track drones, providing high-precision data such as target position, velocity, and flight trajectory, even in complex environments.

Positioning and Tracking Modules:
By utilizing GPS or other positioning technologies, these modules enable real-time location tracking of drones, ensuring effective monitoring of their movement and behavior.

Physical Interception Modules:
These include drone interceptors, net-launching devices, and other physical countermeasure equipment designed to capture, intercept, or force drones to land safely.

Electromagnetic Interference Modules:
These drone jammer modules generate electromagnetic fields or pulses to disrupt a drone’s electronic systems, such as its navigation or communication components, reducing operational capability.

Common Frequency Bands Used in Anti-Drone Systems

Drone jammer modules typically operate across multiple frequency bands, including but not limited to:

2.4GHz Band:
Commonly used for WiFi and Bluetooth communications and widely adopted for drone remote control links.

5.8GHz Band:
Primarily used for video transmission and high-frequency drone control signals.

433MHz Band:
Used by certain low-frequency remote controllers for drones.

900MHz Band:
Often applied to long-range drone control and telemetry communication.

1.2GHz Band:
Mainly used for video transmission, with some drones also utilizing it for control signals.

GPS Frequency Bands:
Used for global navigation and positioning, enabling autonomous flight and waypoint navigation for drones.

Radar Frequency Bands:
Typically operate at higher frequencies and are used for drone detection, surveillance, and tracking purposes.
