Li-Fi: Data Transmission via Visible Light Modulation

Quick fact

Li-Fi can achieve data rates over 100 Gbps in lab settings—more than 100 times faster than typical home Wi-Fi—all by flickering an LED light on and off millions of times per second.

Why this is interesting

You've probably used Wi-Fi to stream videos, but what if the light bulb above you could also deliver your internet? Imagine walking into a room and instantly getting data from the ceiling light—that's the promise of Li-Fi.
