AP-ZONEGUARD

ZoneGuard Wi-Fi is a fast, low-cost way to protect restricted areas in a warehouse without installing cameras everywhere or deploying expensive tracking infrastructure. In many small warehouses, high-value racks and safety zones are marked “authorized only,” but monitoring is manual, delayed, and hard to audit after an incident. Our prototype uses three Wi-Fi access points as reference beacons and reads their signal strength (RSSI) to infer which zone a moving tag/person is in—Zone A, Zone B, Zone C, or a restricted geofence. A simple policy engine then checks authorization: if an unauthorized tag enters the restricted zone, the system triggers an alarm and immediately posts a timestamped event to a dashboard showing zone, RSSI snapshot, and incident history. For tomorrow’s demo, we combine a small rack simulation (top-down map with a moving tag and live logs) with an nRF7002 DK workflow that scans nearby APs and reports RSSI, proving the sensing piece is feasible on the required hardware. This is intentionally a zone-level solution, not centimeter-accurate tracking, but it delivers the key value: instant alerts and a reliable audit trail. Next steps include collecting more fingerprints, adding smoothing for stability, and upgrading the classifier for larger layouts across more shifts.
