The idea is that a wireless signal is encoded in the flickering of the lights fixed to the ceiling or desk lamps. The signal could be reversed by means of LEDs connected to the workstation and light receivers on the ceiling. The new technology could become alternative to radio-frequency WiFi connection.

No one would be bothered by this because the rate of modulation would be millions of times faster than a human eye can see, so lamps with Internet connection could still perform their primary function.

Incandescent and fluorescent bulbs can't flicker fast enough, so all the lights would have to be LEDs.
