At the Optical Wireless Communications Conference 2022, Prof. Harald Haas gave a keynote speech on the role of LiFi in 6G . We look back and looks forward into the challanges and the promises of using light to communicate wirelessly.  Faster and more secure access to the internet by avoiding the congested radio waves.  Lifi can unlock terabit per second connectivity, but is "speed" the only performance indicator?  How will the technology  develop now that the first generations of systems are already in the market. How does LiFi for consumer mass markets differ essentially from shooting laser beams to satellites. 

Professor Harald Haas, then Professor of Mobile Communications at the University of Edinburgh but now with the University Strathclyde Glasgow, coined the term "Li-Fi" at his 2011 TED Global Talk where he introduced the idea of "wireless data from every light".

The interview is conducted by Jean-Paul Linnartz, not only reporter for Radio 4 Brainport but also TPC Chairman of the OWCC 2022 in the MikroCenterum in Veldhoven, Professor in Wireless and Signal Processing Communications at TU Eindhoven himself and Research Fellow with Signify.
