Data Beaming

Infrared data beaming is nothing new and while we’ve probably all got some kind of device with the capability, we rarely use it, aside from turning the TV over of course.

This new technology using visible light could prove to be a more successful and useful alternative.
Instead of using invisible EM wave, visible light is now used to transfer data. The best part about this is that you can identify the reception area visually, stand right below the light source and your PDA would start downloading files.
Other benefits could include date-beaming in sensitive areas hospitals.
The data projector, demonstrated by Matsushita can also act as an indoor lighting source.

No word on transfer speeds but word is it could be comparable to fibre optics.
