I seem to recall HP was touting some kind of optical link system back in the
90's. (IIRC, it was omni-directional infrared.) I think they were suggesting it
for sharing of a printer within a multi-computer office, or for linking test
equipment into a lab's mini-computer.
While I can see some uses where a modulated light source, powerful yet
inexpensive, would be a good data link, I can also see a few problems, the
first of which is bi-directionality and the second is data capacity ahead of
the optical links. As for his hints of vehicular applications, we still haven't
eliminated rain, smoke and fog.
Call me cynical, but whenever somebody puts a box on stage and does magic
engineering, I become skeptical. Whaddya mean, you don't want to get into the
Altogether, Li-Fi is yet another path. Ubiquitous LED's make it more
attractive, but not quite a standing ovation quality concept.

I haven't studied it, but seems to me that one would need to modulate the light
very quickly to get any sort of usable BAUD rate, unless you settle for
transmission of text only. (like the good old Bell 202 modems over voice band

I came over this video ....
Anyone who have studied this tech?
