“This is a groundbreaking pilot project for mobile data communication without the use of radio technology, and a starting point for establishing a new basic technology that can be used where radio technology is not appropriate for health or technical reasons. We are happy that we initiated and coordinated a successful project with partners from the fields of research, politics, and industry”, explain Dr. Andrea Leute and Dr. Stefan Zbornik of the Initiative BodenseeMobilfunk (Lake Constance Mobile Communications).
This project was supported by the Baden-Württemberg Ministry of the Environment, Climate Protection and Energy Sector. The Initiative BodenseeMobilfunk came up with the idea for the project on Mainau Island and also coordinated the activities of the project participants.
Because Visible Light Communication uses LED-based light sources for data transmission, it can naturally deliver a higher number of access points, bringing a significant increase of the network capacity while retaining the mobility which users want. Visible Light Communication also avoids all electromagnetic interferences with radio-based wireless networks and is by definition RF-free. A special modulator turns the LED on and off very quickly, thus transmitting the digital information. Fraunhofer HHI has demonstrated data rates beyond one gigabit per second (1 Gbit/s) with conventional LEDs, supporting the flawless transmission of video data in HD and 4K quality.
