Radio waves and light are both electromagnetic waves. The only difference is their wave lengths. Why would you consider one wireless and the other not?

Sound can also travel without wires. Is that using radio waves?
Seems your degree has given you a very shallow definition of wireless.

I think they use similar technology to this to provide hearing impaired audio to devices in theaters and cinemas. Weird LED array panels mounted high up to the left and right of the stage or screen.
Wonder what bandwidth they can cope with.

(I’ve also seen similar things in museums too).

In my experience “wireless” can be used as a general term and expression of a service that doesn’t need “wires” or physical electrical conductors to connect; it doesn’t have to be strictly linked to “radio”. On the other hand light and radio are all ultimately part of the same animal.

Isn’t this just one way – broadcast communications.

Not convinced about multiple channels from multiple leds either as you’d need excllent optical filters to carve the RGB spectrum up into more than just a few channels.
Transmitting data would probally mean leds at 50% intensity for lighting – tricky when they are already pushed to deliver bright light without overheating.

As a contactless data transfer tech – its interesting. But is this really just similair to multi receiver fibre optics?

It says, ’800Mbps (Megabits per second) capable wireless network by using nothing more than normal red, blue, green and white LED light bulbs’.

From my degree course, wireless implies a radio and not a light source.
