New paper Audio networking: the forgotten wireless technology available. This IEEE Pervasive Computing article explores how audio can be used as a wireless networking technology for mobile devices. We investigated various modulation schemes for transferring data to nearby smartphones through audio signals, covering both the technical aspects and usability considerations. The work included a case study applying audio networking techniques to solve real-world problems in telephone conferencing, demonstrating how this "forgotten" wireless technology could enable new types of proximity-based interactions.
