FPV Interference

Definition: FPV interference refers to unwanted disruption or degradation of the radio/video/control links used by First‑Person‑View drones, causing poor video, control lag, dropouts, or loss of connection.

Common causes: Crowded RF spectrum (other Wi‑Fi/2.4–5.8 GHz users), multipath reflections, physical obstructions, antenna mismatch, or strong nearby transmitters.

Symptoms: Pixelation, latency, frame freezes in the video feed, reduced control range, sudden signal loss, or intermittent noise on the receiver.

Detection & diagnosis: Use passive RF spectrum analyzers, signal strength meters, and logging to identify frequencies, signal-to-noise issues, and intermittent interferers (no jamming or active disruption required).

Mitigation (legal & safe): Improve antenna placement/polarization, switch to less‑crowded channels/protocols, increase link redundancy (diversity antennas, digital links), use higher‑quality transmitters/receivers, or relocate operations to less congested areas — avoid unlawful jamming.

Operational risk & compliance: Interference can create safety hazards (loss of control, crashes) and may breach local spectrum/aviation rules; always follow regulations, coordinate with authorities for contested environments, and prefer detection‑first, non‑disruptive solutions.
