—Rapid RF triage must support not just signalclassification but reliable command delivery under poor linkquality. We extend a normalized 1024-pt FFT with lightpost-filters — previously shown to outperform a tiny CNN(AUROC 0.754 vs 0.671, 48× fewer FLOPs, 1.5 ms p99 at 0dB) — into a live control plane. Using fleet telemetry, we mapconnection quality (signal/100) … Continue reading FFT-Only Spectral Triage for Low-Latency RF Control Planes: From 1.5 ms Digital-vs-Analog Decisions to Near-100% Command Success
