Using mobile technology, carriers scan Bluetooth tags affixed to ULDs prior to loading. Whether on the ground or in the air, real-time connectivity to ULDs via the Descartes Core Bluetooth Low Energy (BLE) network, part of the Descartes Global Logistics Network, allows carriers to access accurate ULD location information and other data, such as precise temperature, movement (e.g., shock, acceleration and orientation), humidity, light and fire. Tags can also be added to any ground service equipment for full control over a carrier’s equipment.
