Quite frankly I couldn't see the benefit. We already have solid state led lasers operating at THz speed. What is the actual improvement in this? Nick Holynak already demonstrated laser transistors more than a decade ago ...

The most interesting thing from this for me was hearing about LiFi, which is a networking technology I have never even heard of being deployed, but apparently is in some environments.

+1 from me.

To me LiFi seems interesting in a number of ways (disclaimer, this is just my understanding) :

- Less interference

- Harder to eavesdrop since it stops in walls

- Higher transfer speeds

Seems like it could replace the current infrared headphones/headsets.

My understanding of LiFi : it's absolutely great apart from when the test room has bright natural sunlight.

That does sound like a significant drawback to wide spread outdoors adoption, and some indoor areas too.

My tv remote works with lights on, why wouldn't LiFi?
