Abstract

Methods (200, 900, 1100) and devices (300, 120, 130, 400, 510, 1000, 1200, 1340) enable tracking using existing mobile networks' infrastructure. A radio module (110, R, 1310) that is attached to a shipment sends one or more network attachment requests including a network-type identifier. Although the requests are rejected, the network records location information if the network-type identifier is actively associated with a shipment identifier.
