Hospital BLE Asset Tracker: RSSI Trilateration (2D)

Interactive 2D canvas simulator of hospital Bluetooth Low Energy real-time locating: a draggable tag broadcasts BLE, fixed ceiling beacons convert noisy RSSI to distance via a log-distance path-loss model, and a from-scratch least-squares solver trilaterates its position — with live charts confirming more beacons and lower noise cut position error.

Real-time locating systems (RTLS) are the "where's the equipment" layer of a connected smart hospital — a Bluetooth Low Energy tag on an infusion pump broadcasts continuously, and a grid of fixed ceiling beacons converts the signal strength of every packet they hear into a distance estimate via the log-distance path-loss model. This 2D canvas simulator renders that floor plan from above: drag the tag or any beacon by hand, or let the tag wander on its own, while beacons compute noisy RSSI-derived distance estimates and a from-scratch least-squares multilateration solver reconstructs its position in real time. Adjustable RSSI noise, path-loss exponent and beacon count let you see directly how signal-strength localization degrades under real-world radio conditions, backed by live Monte-Carlo accuracy charts that numerically confirm more beacons and lower noise shrink position error.
