As Dr. Michael Olsen at OSU notes this is not directly about lidar, but it is about the use of light to replace radio waves to transmit the Internet at blinding speed. By blinding I mean 100 times faster than wi-fi using a light bulb. Yes a light bulb.
These researchers claim they tested it an office environment and achieved 1Gbps (gigabit per second) – incredible. It requires a light source, such as a standard LED bulb, an internet connection and a photo detector. It was tested this week by Estonian start-up Velmenni, in Tallinn.
The term li-fi was first coined by Prof Harald Haas from Edinburgh University, who demonstrated the technology at a Ted (Technology, Entertainment and Design) conference in 2011.
But the technology also has its drawbacks – most notably the fact that it cannot be deployed outdoors in direct sunlight, because that would interfere with its signal.
I think we can live with that, right Starbucks?
