Internet By Light Promises To Leave Wi-Fi Eating Dust (yahoo.com)
schwit1 writes: Connecting your smartphone to the web with just a lamp - that is the promise of Li-Fi, short for 'light fidelity,' which features Internet access that is 100 times faster than Wi-Fi. French start-up Oledcomm demonstrated the revolutionary wireless technology at the Mobile World Congress, the world's biggest mobile fair, this week. As soon as this smartphone was placed under an office lamp, it started playing a video. The big advantage of Li-Fi is theoretical speeds of over 200 Gbps.
The technology uses the frequencies generated by LED bulbs -- which flicker on and off imperceptibly thousands of times a second -- to beam information through the air, leading it to be dubbed the "digital equivalent of Morse Code"
What the hell is that supposed to mean? Is this supposed to be the first digital communication technology that operates by turning something on and off rapidly?
We hope your rules and wisdom choke you / Now we are one in everlasting peace
How does it manage the uplink? Nothing about that in TFA, from what I can see.
If it weren't for deadlines, nothing would be late.
