Apparently it works and is at least 100X faster than WiFi.

What Is Li-Fi, and Will It Replace Wi-Fi? | Innovation | Smithsonian

Li-Fi stands to be much faster than Wi-Fi. In recent experiments, researchers have been able to reach Li-Fi speeds as fast as 224 gigabits per second. At these speeds, a person could download nearly 20 full-length movies in a single second. According to Haas's research, Li-Fi can achieve data density 1,000 times greater than Wi-Fi, because Li-Fi signals are contained in a small area, as opposed to the more diffuse radio signals.


In addition to being faster than Wi-Fi, Li-Fi will be more secure, Haas says. While Wi-Fi signals can pass through walls (allowing your neighbors to “share” your connection), home Li-Fi signals can be kept indoors by drawing the curtains. The system wouldn’t mean having to keep your lights on all the time either, Haas says—bulbs could be dimmed to such a point that they appear off, but still transmit data.

Meh, that is about what ISP promises me already and it sure seems like I am on dial up. I think they over sold their allotment.

Wowww that's fast. Apparently, it relies on subtly blinking LEDs to transmit signals. Would it make it harder to get signals from than WiFi? Would you need LEDs throughout the house to transmit signals? Would you need to have one area always uncovered to receive data?
