Abstract. In this article, we'll review various modulation schemes we've worked with previously, covering how to transfer data to nearby smart phones as well as usability and security issues. We'll consider audio networking as a mechanism for introducing data packets into ongoing mobile phone calls. We'll also discuss some real-world problems reported with telephone conferencing and apply audio-networking techniques to them in a case study application.
