This looks interesting. I happen to have quite a few LEDs laying about, and wonder if I can adapt an old network card or hub to utilize similar technology to work with them instead of wires or RF?

“Li-Fi”?
Isn’t that part of Obamacare marketing?

And any network is only going to be line-of-sight.
Light doesn't pass through walls.

I built something very similar back in Jr HS.
Another Chinese scam looking for funding.

Old tech for networking. Limited to line of sight. Limited throughput. Used IR.

I toyed with the idea of building something like this, but I was thinking of using LED’s for signal acquisition and off-the-shelf CD-player IR lasers for high-bandwidth transmission. The CD auto-focus mechsnism would have to be adapted to multiple-axis pointing and focusing.

The directionality of this could be interesting, but for that, I would go with a modulated low power laser.

Why does Network World have to be excerpted? It’s taking more than a minute to load all the ads and horse crap on that site.

Trying to find out how fast it would operate...
Li-Fi, however, could be deployed in everyday LED bulbs, with light-based Internet connections covering the interior of entire homes or buildings. The data connection speeds can also reach several gigabits per second. Chi’s own system runs at 150 Mbps by using a small number of LED bulbs each at one watt.
“With a more powerful LED light, we can reach 3.5 Gbps speeds,” she added. Both the router and receiver are fitted with LED bulbs so that they can send data, and also installed with a chip that can process the signals.

Because it is dependent on light, the technology can’t penetrate walls or work in complete darkness.
***Wouldn’t complete darkness make an LED based system work BETTER?

Would this not be much more secure, in that the broadcast area of light can be better contained?
