Patent attributes
A method and system of Passive Mode Tracking of an item, object or cargo associated with a wireless communication device through existing and future wireless networks is described. The method builds on the observation that for many applications, cargo tracking included, an exact GPS or comparable accuracy method of location is not always necessary, however, the progress or rough movement, is. Therefore it is possible to utilize the tracking units' geographical location based on the registration process of a wireless service and its associated networks to locate the tracking unit. This method improves the size, weight, power consumption and complexity of the tracking unit by removing work from the tracking unit and utilizing the information collected by the wireless system(s) and the network(s) it attaches to. The location of the tracking unit is determined by inquiring of the wireless network the location of the wireless communication device.
