UNITA

The area of Internet of Things (IoT) gained increasing importance in recent years. More and more everyday devices become smart and connected. Most of today’s IoT devices communicate via Wireless LAN or Bluetooth, which requires an external network and available sensors. This master thesis focuses on the development and construction of an ultrasonic communication infrastructure, i.e. ultrasonic beacons, which should provide an alternative way of communicating for IoT devices. These beacons should send and receive ultrasonic information and can connect with the internet for data exchange. With those beacons it should be able to create a network, which can be used to connect smartphones, smartwatches and other IoT devices with each other and the internet. As a proof-of-concept, a mobile app should be developed that communicates with the beacons and visualizes the network activity and status. The application will be implemented as Android application.
