6G Optical Communication

Visible Light Communication

We must offer secure extreme data rates in various scenarios in 6G. This demonstration shows how radio and light technologies can be combined. We can use relatively simple technology to implement light-based communications as we exploit the lighting infrastructure that we have in our ceilings.

We envision that in the future, light and radio will complement each other. Thus, empowered users will have the possibility to decide whether to use radio, or whether to use light.

Light has a lot of advantages including a large amount of spectrum which is unlicensed and free to use. With light, we can also support very high data rates, even hundreds of gigabits per second.

Light-based communications is also very secure because the light signal remains confined in the room where we are. No one outside of the room can listen to our communication which makes the communication very secure and private.

This Visible Light Communication Demo is part of the 6G Demo Series showcasing 6G Flagship program’s 6G innovation.
