Method and system for localizing tracking devices indoors and outdoors
First Claim
1. A tracking device for localizing an item comprising:
- a processor; and
a memory storing a set of instructions, the instructions executable in the processor to;
identify a location state of the tracking device as one of an indoor location and an outdoor location relative to an indoor facility, based on at least one of satellite based data and connectivity to an access point in the indoor facility;
upon identifying the location state as the indoor location, activate a an inertial sensor and at least one of a wireless transceiver and one or more sensor devices of the tracking device, the sensor devices including at least one of a wireless signal strength sensor, a wireless signal connectivity sensor, a magnetic field sensor, a barometric sensor, and an ambient light sensor;
periodically broadcast a short range wireless signal to one or more other tracking devices within a predetermined distance from the tracking device in the indoor facility to enable localization of the one or more other tracking devices;
receive short range wireless signals broadcasted by the one or more tracking devices; and
provide indoor localization data gathered by the one or more sensor devices to a nearest access point, the indoor localization data comprising at least one of signal data and sensor data, the signal data comprising data pertaining to the short range wireless signals received from the one or more other tracking devices, the data pertaining to the short range wireless signals being used for determining a position of the tracking device relative to the one or more other tracking devices and the sensor data comprising at least one of inertial data and ambient environment data, the indoor localization data being used for localization of the item in the indoor facility.

Abstract
A method and a device for tracking an item using a tracking device associated with the item are described. The method, executed in a processor of the tracking device, comprises identifying a location state of the tracking device as one of an indoor location and an outdoor location relative to an indoor facility, based on at least one of satellite based data and connectivity to an access point in the indoor facility. Upon identifying the location state as the indoor location, a wireless transceiver and one or more sensor devices may be activated. The sensor devices may include at least one of a wireless signal strength sensor, a wireless signal connectivity sensor, an inertial sensor, a magnetic field sensor, a barometric sensor, and an ambient light sensor. Further, indoor localization data gathered by the sensor devices may be provided for localization.
