Abstract
A system includes an asset tag associated with an asset, the asset tag having a motion sensor to detect a movement of the asset. The system also includes a plurality of readers, each reader receiving one or more signals from the asset tag and measuring a distance between the asset tag and the reader based on the signals. The system further includes a controller receiving a measured distance from each of the plurality of readers and determining a location of the asset based on the measured distances.
