Abstract
Aspects of the disclosure include a device for geo-fence monitoring. The device includes a first positioning circuit, a second positioning circuit, and a control circuit. The first positioning circuit is configured to determine a position of the device before becoming inactive. The second positioning circuit is configured to determine an estimated distance that the device travels relative to the position. The control circuit is configured to reactivate the first positioning circuit when the estimated distance exceeds a first predetermined threshold and a difference between a current wireless fingerprint and a previous wireless fingerprint exceeds a second predetermined threshold.
