Abstract
An item tracking system that uses smart tracking labels to track an item's position, and that switches between short-range tracking within a local area using short-range interfaces like Bluetooth and long-range tracking within a global or regional area using long-range interfaces like GPS. Long-range communication interfaces may be disabled when the tracking label comes within range of a short-range network such as a Bluetooth network within a warehouse. Switching to short-range services when they are available may significantly reduce the total power requirement for a tracking label. In an illustrative embodiment a tracking label may periodically broadcast an advertising message over Bluetooth; when a Bluetooth gateway in a warehouse or other local area responds to this message, the label disables long-range interfaces and switches position tracking to use short-range services. When the label loses communication with a short-range network, it re-enables the long-range interfaces.
