Abstract
Wireless Fidelity (Wi-Fi) is very popular today. Every place including homes, offices, colleges, other public places have hotspots to access internet through Wi-Fi. This increased number of users and thus the usage of bandwidth has lead to congestion in the radio spectrum. So, to overcome this problem of radio crisis, Light-Fidelity (Li-Fi) came into existence in 2011, which uses visible light region for data transmission. This visible part of spectrum is 10,000 times greater than the radio part being used in Wi-Fi. Li-Fi is basically the subset of Visible Light Communication (VLC), makes use of LED bulbs to transmit data using light as a medium. In other words, we can say that it uses LED bulbs as hotspots and provides higher data rates than Wi-Fi. In this paper, survey has been done on both technologies using certain common parameters and the possible research scope of this technology is elaborated.
