Indoor location tracking finds workers inside buildings where GPS is weak. It uses Wi-Fi signals, Bluetooth Low Energy beacons, ultra-wideband anchors, or RFID checkpoints to work out where a worker’s device is, then shows that position to supervisors and responders.
Accuracy depends on the method. Wi-Fi is usually room or zone level, Bluetooth is typically a few meters, and ultra-wideband is the most precise but needs the most hardware. Tracking matters most when something goes wrong: an SOS or man-down alert that arrives with a location lets responders go straight to the worker. The Walt Smart Radio System by weavix combines voice, SOS and man-down alerts, and location on one device.
