Abstract: An object position-measuring device, a method thereof, and a system thereof are proposed. The object position-measuring device, method thereof, and system thereof are for measuring a position of an object by using a plurality of wireless signals indoors. In the object position-measuring device, method thereof, and system thereof, respective distances from the position-measuring device and first and second wireless communication devices to the object are calculated by using respective travel times of the wireless signals respectively transmitted from the position-measuring device and the first and second wireless communication devices and the wireless signals received after being reflected from the object, whereby the position of the object is measured by using the calculated distances.
