The frequency table provides a list of frequency bands used for UAV video transmission, including commonly used bands for FPV (First-Person View) systems such as DJI, Walksnail, HDZero, and others. The data includes bands ranging from 460 MHz to 6.18 GHz, covering analog and digital video transmission across various manufacturers.

The information is valuable for counter-UAV operations, particularly in detecting, jamming, or disrupting unauthorized drones.

Detection and Identification

Understanding these frequencies allows for the development of spectrum monitoring tools that can scan for signals within these bands. If an active transmission is detected within a known UAV frequency range, the presence of an operating drone can be confirmed.


Jamming

To disrupt drone video feeds, targeted jamming signals can be deployed against specific frequency bands. The table shows which frequencies are most commonly used, allowing for precise jamming that minimizes collateral interference with other systems. For instance, DJI drones frequently use 5660-5914 MHz in 25 Mbps mode, so targeting this range can disrupt the video feed and control signals.


Denying FPV Control

Many FPV drones rely on continuous video feedback for navigation. Jamming the video transmission frequencies will cause FPV pilots to lose visual control, forcing a manual recovery or emergency landing.


Spoofing and Signal Manipulation

If a counter-UAV system is sophisticated enough, it could inject false signals into these frequency bands, disrupting the drone’s ability to maintain a stable connection with its operator.


Frequency-Hopping and Adaptive Jamming

Many modern UAV systems use frequency hopping techniques to avoid interference. Countermeasures must incorporate frequency agility and dynamic spectrum monitoring to track and jam moving targets effectively.
