DETECTION OF WIDE AREA WIRELESS NETWORKS

摘要

A method to track a movable asset which uses a device attachable to the movable asset, whereby the device includes a transceiver adapted to communicate over a wireless wide area network. The device operates from battery power stored in a battery attachable within the device. The device is configured to conserve the battery power and a datum which pertains to the asset is logged. While the transceiver is powered off, an ambient radio frequency signal of the wireless wide area network is monitored. Upon the ambient radio frequency signal being detected above a threshold, the transceiver associated with the available mobile network channel is powered up.

1. A method for tracking a movable asset using a device attachable to the movable asset, whereby the device includes a transceiver adapted to communicate over a wireless wide area network, wherein the device operates from battery power stored in a battery attachable within the device, wherein the device is configured to conserve the battery power, the method comprising:
logging a datum pertaining to the asset; while the transceiver is powered off, monitoring an ambient radio frequency signal of the wireless wide area network; upon detecting the ambient radio frequency signal above a threshold,
powering up the transceiver associated with the available mobile network channel; uploading by the transceiver the logged datum; upon completing the upload, powering off the transceiver in order to conserve the battery power.
