Visible Light Communication (Li-Fi Technology)

Nowadays, communication technologies including Wi-Fi and Bluetooth are using radio signals in transmission of data from one place to another. However, the scope of world is always to do something improved, innovative and technical which has more benefits and ease of use. This results in foundation of Li-Fi technology, which has its own several benefits over other technologies and many researchers are still working on it to delimit its restrictions and cover up the spaces required to fill up the advancement gap in order to completely implement this technology on large scale. Li-Fi is preferred most due to its overwhelming speed of data transmission. It works hundred times faster than Wi-Fi and it uses visible light spectrum as medium of transmission which gives wide range of bandwidth. In this paper, brief introduction, working principles, merits and demerits, and more specifically possible solutions to the limitations of Li-Fi technology will be discussed.
