LPI
A property of transmissions designed to be difficult for an adversary to detect, intercept, or locate, using techniques such as spread spectrum, frequency hopping, and low power. LPI links make passive RF detection of an emitter much harder.

Why it matters
Low-probability-of-intercept design keeps a transmission hard for an adversary to detect or locate; for an operator it protects both the link and the position of whoever is transmitting.

What is LPI?
A property of transmissions designed to be difficult for an adversary to detect, intercept, or locate, using techniques such as spread spectrum, frequency hopping, and low power. LPI links make passive RF detection of an emitter much harder.
Why does LPI matter for defense and counter-UAS operators?
Low-probability-of-intercept design keeps a transmission hard for an adversary to detect or locate; for an operator it protects both the link and the position of whoever is transmitting.
