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.

    How does it manage the uplink? Nothing about that in TFA, from what I can see.

    I doubt it. Until you get down into MUCH lower frequencies, the bandwidth is limited by the speed with which you can modulate (and detect the modulation of) the light rather than the frequency of the light itself.

    Stop it. Just stop it.
    Also, can we just agree to stop adding "gate" to the ends of the things bad people do?
