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?
At 11 mins in to this his TED talk Harald Haas talks about using Li-Fi to enable cars to communicate with each other.
