This research considers a short-range communication system using smartphones for when wireless communication lines are down. Acoustic communication technology is used for exchanging information in this system. That technology does not require any special device features other than speakers and a microphone. A fundamental investigation into the effectiveness of the proposed method is carried out in this research.
