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?

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.

Light reflects off most surfaces so not necessarily.
