Asset Tracking

Ultra-wideband (UWB) provides centimeter-level indoor positioning accuracy using time-of-flight measurement between devices. RFID (Radio Frequency Identification) uses passive tags requiring no battery, activated by reader radio waves, with Impinj M800 series achieving read ranges of 12+ meters. Bluetooth Low Energy (BLE) beacons provide meter-level indoor positioning with 7+ year battery life. LoRaWAN provides long-range, low-power wide-area connectivity with satellite integration enabling tracking in areas without terrestrial networks. GPS provides outdoor positioning using satellite signals with meter-level accuracy. Cellular IoT (NB-IoT, LTE-M) provides wide-area tracking with carrier-grade reliability.

Walmart's RFID mandate tracks nearly all general merchandise across the supply chain from manufacturer to store shelf. Apple AirTag leverages a billion-device Find My network for consumer item tracking. Zebra Technologies' enterprise solutions track assets across warehouses, hospitals, and manufacturing facilities. UWB positioning provides centimeter-level accuracy for healthcare asset tracking (equipment, staff, patients). LoRaWAN satellite integration tracks shipping containers and agricultural equipment in areas without cellular coverage. project44's platform provides real-time multimodal supply chain visibility as a 5-time Gartner leader.
