Systems and methods for power efficient mobile device communication

Abstract:

Methods, devices, and systems for tracking an asset are provided. In particular, a device is provided that includes a processor; a wide-area network radio; a global positioning system (GPS) receiver; an accelerometer; and a physical interface. The processor determines a GPS signal is unavailable. In response to determining the GPS signal is unavailable, the processor enables one or more sensors. The processor obtains fingerprint data from a first sensor of the one or more sensors. The processor transmits the fingerprint data to a network-based server. The fingerprint data is used by the server to identify a location of the tracking device.
