Chirp has released a white paper available for download for IoTC members entitled Data over Sound Technology: Device-to-device communications & pairing without wireless radio networks (click to download).
We are starting to see the early signs of a surge in wireless Data-over-Sound (DoS) applications: the use of audio signals through the air, as a mechanism for sending data between devices. While the concept is not new, its current growth is being fueled by the rise of smartphones, IoT devices and improved signal-processing technology.
This white paper addresses:
Why is Data-over-Sound Useful?
Key technology enables of DoS
Example use-cases and applications of DoS
Commercialization pathways, opportunities & risks
