Provided is an ultrasonic-wave communication system where the influence of ambient noise and the Doppler effect are suppressed and where a user of a portable terminal is prevented from hearing unwanted sound. After performing encryption processing of store information, a beacon 5 placed in a salesroom 3 sends out store-information-containing beacon information of one channel as ultrasonic waves into the salesroom 3 by combining a control carrier, a first carrier, and a second carrier in such a way that a first carrier signal and a second carrier signal are output between control carrier signals a number of times according to the store information and that a state where the first carrier signal and/or the second carrier signal is output is maintained.
An ultrasonic-wave communication system which performs communication using ultrasonic waves between a beacon which emits ultrasonic waves and a portable terminal, wherein:
A beacon used in an ultrasonic-wave communication system which performs communication using ultrasonic waves between a beacon which emits ultrasonic waves and a portable terminal, wherein:
A non-transitory computer readable memory storing a portable terminal program used in an ultrasonic-wave communication system which performs communication using ultrasonic waves between a beacon which emits ultrasonic waves and a portable terminal, the program being executed in a CPU installed in the portable terminal to cause the CPU to:
A program-providing server capable of communicating with a portable terminal used in an ultrasonic-wave communication system which performs communication using ultrasonic waves, via a network, between a beacon which emits ultrasonic waves and a portable terminal,
