Covert Wireless: Practical Low Probability of Intercept & Detection (LPI/LPD)
Wireless Warrior analyzes military Low Probability of Intercept (LPI) and Detection (LPD) radio techniques, demonstrating stealthy amateur RF designs.
Summary
Commercial vs. Tactical Wireless Paradigms
While commercial wireless protocols prioritize high data throughput and universal beaconing, tactical communication systems require absolute RF stealth to avoid detection and electronic location.
Principles of Low Probability of Intercept and Detection (LPI/LPD)
Wireless Warrior explains direct sequence spread spectrum (DSSS), frequency hopping (FHSS), burst transmission, and operating below the thermal noise floor.
Designing Covert RF Links on Civilian Frequencies
The speaker demonstrates constructing low-power, directional, spread-spectrum transceivers using software-defined radios and custom modulation schemes.
Techniques for Counter-SIGINT and Direction Finding Evasion
The presentation reviews antenna shielding, terrain masking, and duty-cycle throttling to evade adversary spectrum analyzers and radio direction finders.
