Infrared may no longer be a punchline, as IEEE approves 9.6Gbps wireless light

Am I correct that this would require direct line-of-sight for any device using an antenna[0] enabling this? It seems a bit impractical for your typical consumer use-cases if so, but maybe beneficial for some more commercial scenarios.

Would love to know if I am wrong here though! It seems very interesting.

The idea is to put it in the ceiling (lightbulbs).

Light bounce also works, so if you are in a typical room the walls also become antennas.

So if you turn your back on the ceiling light you lose your connection?

Light reflects off most surfaces so not necessarily.

I think the idea is you have normal wifi as well, so you should never lose the connection but certain preferred positions will go much faster using light.
