Using Visible Light to Transmit Data

Posted April 12, 2015 12:00 AM by Engineering360 eNewsletter

As development and testing of super-fast 5G systems continues, engineers are thinking about using a different part of the electromagnetic spectrum for data transmission. At the recent Mobile World Congress, they were talking about light fidelity or Li-Fi for data communications. And UK's pureLiFi Ltd. is exploiting the opportunities presented by this technology using smart LEDs.

The idea of LiFi has been around for a few years now.

It will, like all other data reticulation methods find its niche and prosper.

It would seem a little prone to interference from ambient light though. Also won't work in a dark cupboard or in a pocket....it will find a niche though and be the best choice for that, just like all the others.

Navies were using light-based digital communication in the 1800's. It was called Morse Code using flashing shutters. Line-of-site was required, however!
