Tracking device power preservation through signal strength reduction

摘要

The power consumption of a tracking device can be reduced by managing the transmission power of the tracking device when a mobile device is at the edge of the range of the tracking device. A connection can be established between a tracking device and a mobile device at the edge of a first range of the tracking device. The transmission range of the tracking device can be reduced to sever the connection between the tracking device and the mobile device. After a pre-determined time interval or after a connection with the mobile device is re-established the transmission range of the tracking device can be restored.

主权项

1. A method for conserving power for a tracking device, the method comprising:
establishing, by the tracking device, a communicative connection with a mobile device, the mobile device located at a periphery of a first transmission range of the tracking device; receiving, by the tracking device from the mobile device, an instruction to reduce the transmission range of the tracking device to a second transmission range, the instruction sent in response to a determination by the mobile device that the mobile device is located at the periphery of the first transmission range of the mobile device; reducing, by the tracking device, the transmission range of the tracking device to the second transmission range such that the communication connection between the tracking device and the mobile device is severed; in response to re-establishing a connection with the mobile device while the transmission range of the tracking device is the second transmission range, increasing, by the tracking device, the transmission range of the tracking device to the first transmission range; and in response to passage of a pre-determined interval of time without re-establishing a connection with the mobile device, increasing, by the tracking device, the transmission range of the tracking device to the first transmission range.
