Frequency hopping
A technique in which a transmitter rapidly changes carrier frequency across a known pseudo-random pattern, so a signal never dwells long on any one channel. It resists both narrowband jamming and easy interception.

Why it matters
Frequency hopping makes a link hard to jam or intercept because it never dwells on one channel; for an operator it both protects friendly comms and complicates countering an adversary’s.
Standards & authorities

Frequently asked
What is Frequency hopping?
A technique in which a transmitter rapidly changes carrier frequency across a known pseudo-random pattern, so a signal never dwells long on any one channel. It resists both narrowband jamming and easy interception.
Why does Frequency hopping matter for defense and counter-UAS operators?
Frequency hopping makes a link hard to jam or intercept because it never dwells on one channel; for an operator it both protects friendly comms and complicates countering an adversary's.
What standard or authority governs Frequency hopping?
Frequency hopping is defined or governed by MIL-STD-188 series (spread-spectrum communications).
