Abstract:
The present invention relates to a location information providing system using ultrasonic region division, which can divide an ultrasonic region and match location information of tunnels, buildings, etc. with service signals obtained by combining same, and thus can match almost infinite location information with different service signals. The present invention comprises: a service server (100) that divides an ultrasonic wave into a plurality of channels and combines same so as to generate a service signals, and matches location information with the generated service signal; an ultrasonic wave generating device (200) that is installed at a place where the location information is provided and transmits, to the outside, an ultrasonic wave corresponding to the service signal generated from the service server (100); and a client (300) that verifies the service signal corresponding to the ultrasonic wave when receiving the ultrasonic wave transmitted from the ultrasonic wave generating device (200), provides information corresponding to the verified service signal to the service server (100), and effects guidance upon receiving location information matching with the service signal from the service server (100).
