RAFA (RAdio Frequency Attack) implements a robust wireless UAP that models channel distortion and sample misalignment to craft over-the-air perturbations. A single-antenna attacker (USRP + router) transmitting 20x less power than the client and without synchronization causes up to ~7 dB SNR loss against FIRE (ML channel prediction) and increases D-LOC localization error by ~0.7 m median and nearly 3 m at the 90th percentile across 16 client locations, and adversarial training with RAFA examples partially restores performance.
