APPARATUS AND METHOD FOR MEASURING LOCATION

摘要

An apparatus for measuring a location is to perform a first position by using a signal quality information for multiple beacon signals respectively received from a plurality of signal transmission portions that are respectively mounted on a plurality of exclusive broadcast devices disposed in an interior space, to perform a second position by using a receiving signal of multiple ultrasonic wave signals received from the signal transmission portions, and then to determine the position of the devices in the interior space based on the result of the first position and the second position.
