LI-FI is wireless and uses visible light communication or infrared and near ultraviolet(instead of radio frequency waves), part of Optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.
LI-FI NETWORK:
A wireless local area network based on Li-Fi technology needs some additional features to provide the same qualities as an RF-based wireless network, without losing the main advantages Li-Fi technology is able to provide. Here are the missing links for a fully developed Li-Fi WLAN.
The Li-Fi room connector
Optical signals are not able to penetrate walls. This is an advantage in relation to security issues. However, in order to provide an optical wireless local area network, rooms need to be connected with each other. This is achieved via the Li-Fi room connector. The Li-Fi room connector is a replicator which sends the data stream from one side of the wall to the other via an optical fiber cable, which connects the two room connectors on each side of the wall. With smaller rooms, the Li-Fi room connector might be sufficient as the only Li-Fi hotspot in the room.
The Li-Fi router
The Li-Fi router is the network connection to the external link (fiber optic cable, DSL, GigE, etc.). The application is mainly useful for small office or home use with cloud & server functions. It connects office and/or entertainment equipment and covers a radius of 20 meters with a 100 Mbps transmission speed.
