Fraunhofer HHI completes optical WiFi project
The “VLC Mainau” project was launched in the spring of 2015 with the objective to convert an existing conference room on the Island of Mainau (Lake Constance) using Visible Light Communication (VLC) technology.

Now the project has been successfully concluded by the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI and Mainau GmbH with the realization of a novel optical WiFi environment.

The conference room system was upgraded in several phases intended to offer insights about parameter optimization in view of practical applications. This VLC installation outside a laboratory environment is the first in Germany and one of the few field tests of this kind worldwide.

A first VLC-based system was installed in the conference room during the first project phase. Also known as LiFi, the VLC technology is a WiFi alternative that supports the wireless exchange of large data volumes. The VLC technology was then expanded in the second project phase, providing flexible access to the Internet for multiple users.

“This first VLC installation on the Island of Mainau was a very exciting project for us. We very much appreciate the constructive collaboration with Mainau GmbH and the financial support of the Baden-Württemberg Ministry of Environment. Today we are looking back on one year of continuous, error free operation of the installed system. Highly positive feedback from users shows that this technology will find a place in everyday life. The constructive comments are already being implemented into the further development of our systems today”, says Dr. Anagnostis Paraskevopoulos, Project Manager at Fraunhofer HHI.

Bettina Countess Bernadotte, Managing Director of Mainau GmbH, is supporting the research of reduced radiation mobile communication based on personal conviction. “We as the Island of Mainau are pleased that we were able to make a contribution to the further testing of the new technology, and we look forward to its subsequent development.”
