The client connection confirmation unit 108 confirms the connection of the client 300 while communicating with the client 300. The client 300 may be automatically connected through an application, an embedded program, or the like installed in the client 300.

When the location information selection unit 110 receives the information on the service signal from the connected client 300, the location information selection unit 110 checks the same service signal compared to the service signal registered in the service signal-location information DB 126, and the same service signal If is confirmed, select the location information matching the service signal.

The location information transmitting unit 112 provides the location information selected by the location information selecting unit 110 to the client 300 that has transmitted the service signal.

Through this process, the service server 100 may generate a plurality of service signals by separating specific areas of the ultrasound into channels and combining them, so that even if a plurality of location information is registered, all of them can be matched.

On the other hand, the ultrasonic wave generator 200 transmits the ultrasonic wave corresponding to the service signal matched with the location information to the client 300 to the outside. Information about the ultrasonic wave generated by the ultrasonic wave generator 200 may be provided while communicating with the service server 100.

The ultrasonic generator 200 refers to various media devices including a speaker capable of generating ultrasonic waves or a TV, a computer, or the like connected to the speakers. In this case, the ultrasound generator may generate a plurality of location information through a plurality of speakers installed at a location where different location information is displayed, such as a tunnel or a building. For example, the ultrasonic generator transmits 18,500 Hz and 18,525 Hz ultrasonic waves in the A position, 18,500 Hz and 18,550 Hz ultrasonic waves in the B position, and 18,500 Hz, 18,525 Hz and 18,550 Hz ultrasonic waves in the C position. Is sent.
