Popular wireless personal area network technologies are usually based on short radio waves. Notable examples are Bluetooth, ZigBee and Wi-Fi. In this paper, we describe a MAC protocol for wireless networks, mainly for Android smartphone devices, based entirely on high frequency sound waves. Beyond the human hearing range, ultrasonic waves are a good and cheap complementary solution for environments where other forms of communications are disabled or interrupted. Our main contribution is a packet-based MAC protocol for wireless ultrasonic networks that supports generic and low-bandwidth applications such as smart home, remote control, and entertainment devices.
