An LED (Light Emitting Diode) is just a solid state junction that emits light in response to an applied voltage.
These junctions can be switched amazingly fast - making them ideal for data transmission.
So forget Wi-Fi, the talk is now about Li-Fi networks. Li-Fi is short for light fidelity. What an interesting idea.. tiny LED lights transmitting data with massive bandwidth.
