With the emergence of the first affordable, widely available computers, the demand for applications requiring reliable and efficient data communications both between and within networks rose at a staggering pace. Soon, the internet - the worldwide web of heterogeneous networks - had evolved to establish world wide connections between our gadgets. Today, millions of our everyday devices have access points to the internet. In the age of the Internet of Things (IoT), improving the existing communications technologies and developing new solutions is crucial. The paper describes a system built around a sound based communications protocol employing the microphone and speakers of widely used devices to provide a useful alternative to the solutions currently present on the market. The first section provides a summary of what lead to the age of IoT and the fundamental steps leading to today’s network schemes. Then, I will present the technological background that provided the foundation of the design. In the next chapter, I will introduce the core of the system the communication protocol. In the System design section I will outline a general solution to the task and then I will touch upon some data protection issues. In the last section I will provide an example for implementation, especially with regards to aspects of scalability.
