LiFi
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.
