Harald Haas coined the phrase “LiFi” in 2011, and now he’s telling us it’s ready to enter version 2.0. He joins the Get a Grip on Lighting Podcast from the floor of the second Global LiFi Congress, June 2019, to catch us up on the history and development of light-based data transmission, its current applications in the fields of autonomous automobiles, privacy and security, as well as defense. LiFi represents a paradigm shift for the lighting industry comparable to the one photography underwent with the introduction of digital cameras - lamps are going the way of film stock and the industry needs to begin to consider itself a platform creator for the Internet of Things through the power of LiFi. If the tech sector is going to keep adding brains to everything, then LiFi should become both the nervous system and communication tool for all of these smart devices.
