Light-Fidelity: Next Generation Wireless Networks- A Survey

This is the age of speed and everybody requires high speed connectivity to connect with others for sharing useful and necessary information. Presently the most commonly used network is Wi-Fi (IEEE 802.11n) whose maximum speed is around 150mbps. Though this much speed is capable for transmitting lots of information but yet there are hundreds of consumers for whom this is a kind of restriction. For this very reason in 2012, a German Physicist Harald Hans proposed a wireless solution by the name Li-Fi, that is Light Fidelity whose peak transmission rate is 8 Gbps[1]. Light fidelity (Li-Fi) basically refers to an optical networked communication that depends on visible light communication (VLC) to diverge and manage the traffic of mobile data, offering a plethora of advantages when used in an indoor scenario. This article aims to study and analyze the various aspects of Li-Fi and the state-of-the art development made in the field.
