A Russian company is selling its Li-Fi based wireless LAN solution (a visible light communication technology that uses light from light-emitting diodes to deliver internet) in the U.S., Israel, China, and other countries.
The core of the network is a router that is capable of transmitting a signal using a light beam at a distance of up to 23-26 feet (7-8 meters). The signal can be transmitted to eight devices at once in other parts of an office, and access speed is four times faster than standard Wi-Fi.
Li-Fi is unique in that it creates a digital binary code with a light beam, while Wi-Fi transmits data using radio waves.
