Abstract
A method capable of providing a low power geofence service according to the present invention comprises the steps of: detecting a reference Vrect value for estimating an indoor/outdoor position from a solar charger of a position tracker; determining whether the solar charging module (solar charger) of the position tracker is in a charging or non-charging situation, on the basis of the detected Vrect value; if it is determined that the solar charging module of the position tracker is in the charging situation, determining that the position of the position tracker is outdoors and acquiring position tracking data by using a global positioning system (GPS) module; if it is determined that the solar charger of the position tracker is in the non-charging situation, determining that the position of the position tracker is indoors or in a shaded area, and acquiring position tracking data by using one among Bluetooth low energy (BLEs), wireless fidelity (Wi-Fi), and ultra-wide band (UWB) modules other than the GPS module; and transmitting the acquired position tracking data to a server by using a low power communication scheme.
