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.

- metaobject 10y agoOne 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.
