Are they trying to re-invent Li-Fi ? https://en.wikipedia.org/wiki/Li-Fi https://en.wikipedia.org/wiki/Li-Fi

  the article is easily digestible and you'll find that no, they aren't. not even close.

    Hm, they seem similar because both Li-Fi and free-space optical communication (FSO) use visible or near-visible spectra to send and receive information. I guess they might be seen differently as Li-Fi is potentially designed for indoor use? I don't see why they are substantially different, however, or at least incomparable.

      One significant difference is that FSO operates over a much longer distance and has to contend with atmospheric interference (clouds, turbulence, etc). Also, the transmitter/receiver hardware used is much different.
