Components for Visible Light Communication up to 3 Gbit/s

The newly developed patent protected components have now enabled exploitation of a much higher bandwidth of up to 180 MHz and achieved a transmission rate in laboratory experiments of over 1 Gbit/s per single light frequency. As off-the-shelf white light LEDs mainly use three light frequencies or light colors (RGB), speeds of up to
3 Gbit/s are feasible.

Development of the components as modules makes them suitable for customized integration in technology developments such as Car-to-X communication. But visible light communication also has a broad array of other possible applications ranging from areas like hospital operating theatres where safety is at a premium to places like trade shows and factory halls where radio communication is problematic.
