UNITA - Ultrasonic Network for IoT Applications

Developing and constructing an ultrasonic communication infrastructure, as alternative way of communication for IoT devices

Background

The 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 WIFI or Bluetooth, which requires an external network and the availability of sensors.

Project content

UNITA focuses on the development and construction of an ultrasonic communication infrastructure, i.e. ultrasonic beacons, to provide an alternative way of communication for IoT devices. These beacons send and receive ultrasonic information and connect with the internet for data exchange. They create a network able to connect smartphones, smartwatches and other IoT devices with each other and the internet. As a proof-of-concept, a mobile app was developed that communicates with the beacons and visualizes the network activity and status. The application was implemented as Android application.
