Abstract
Light Fidelity (Li-Fi) refers to the 5G Visible Light Communication systems using light-emitting diodes as a medium for high-speed communication in a similar manner as Wi-Fi.[5] As now a days where internet has become a major demand, people are in a search for Wi-Fi hotspots for their activities. Li-Fi is a better alternative to Wi-Fi in wireless communication as it is[1] bidirectional, high speed and fully networked wireless communications similar to Wi-Fi. It is a subset of visible light communication(VLC) and can be a complement to RF communication , or a replacement in contexts of data broadcasting. This paper proposes a survey on Li-Fi Technology. Li-Fi has more capacity in terms of bandwidth in visible region therefore it does not interfere in other communications which uses radio frequency range, without taking its frequency bands. It has thousand times greater speed than Wi-Fi.Such technology has brought not only greener but safer and cheaper future of communication.
