So how does this new light-based system work? It all hinges on the unique properties of LED lamps. Though you’ve probably never noticed it, the bulbs flicker on and off thousands of times a second, a rate imperceptible to the human eye but one that generates a frequency readable by machines. This frequency is incredibly fast, especially compared to the radio waves used for conventional wireless internet.

Laboratory tests have found that Li-Fi can transmit information at almost unbelievable speeds, over 200 gigabytes per second. That’s fast enough to download 23 DVDs’ worth of information in the literal blink of an eye.
