UK Researchers Build Micron LED Light Based Wireless Network
Mark.JUK writes "Scientists working at the University of Strathclyde in Scotland (United Kingdom) have begun to develop a new Light Fidelity (Li-Fi) technology that will use special micron-sized LED (Light-Emitting Diodes) lights, such as those that could be used as part of home lighting or TV displays, to form part of a sophisticated wireless communications network (much like Wi-Fi is today). The principle, which revolves around manipulating the on/off flicker of LED lights to produce a digital network (a bit like Morse Code from a torch), is not new but most of the other teams are focusing on larger Li-Fi LEDs of around 1mm square in size. However micron sized LEDs not only allow you to use more lights (each of which can act as a separate data channel) but they can also flicker on and off around 1,000 times quicker than the larger LEDs."

Thanks for the clarification, News for Nerds.
If this system sends data with light, but through the air, I would call it "fiberless".
So say we all
LED room lights will double as "Li-Fi" wireless nodes
Li-Fi Multi-tasking micro-lights could spark a communications revolution
I am Slashdot. Are you Slashdot as well?
about this
This sounds ideal for low-bandwidth line-of-sight communications, like for example changing channels on a TV.
My God! That's brilliant! Control the TV remotely. What would be a good name for that?
"For every expert, there is an equal and opposite expert"
Being able to control a tv using a remotely emitting, modulated, optically transmitting effector would be a great breakthough indeed.
I'm not a coward by any name.
