Ultrasonics for Local Area Communication

I intend to examine the prospects of ultrasonics for wireless, local area communication. In other words, I will try to decide whether or not it might be feasable to create a system for objects in the same room to communicate with one another by sharing information through ultrasonic sound. To do this, I will work through issues such as the spectrum, transducers, beam width, transmission distance, bandwidth, and noise.

This work builds on the work done by Vadim Gerasimov, in the Things That Talk project, that transmits data by sound in the audible range. His site is a good starting point to visit before working through this information.
