Transfer of data from one place to another is one of the most important day-to-day activities. The rate of increase in use of mobile communication is very high. The current wireless networks that connect us to the internet are very slow when multiple devices are connected. Different wireless technologies are used for wireless communication such as Li-Fi, WI-Fi and WIMAX. In our research work, a relatively new technology is studied and analyzed i.e. (Li-Fi) light fidelity. The subset of visible light communication LI-FI is 1000 times faster than Wi-Fi and much efficient than WIMAX. Li-Fi is based on “data through illumination”. The VLC modulates the intensity of light from LED array which is detected by photo detector (PD) and then demodulated to produce electronic array. In this research work, the comparison is performed between Li-Fi and existing wireless technologies such as Wi-Fi and WIMAX. It is found that Li-Fi is better than existing wireless technologies in terms of speed, safety, cost, security, bandwidth and applications.
