Light Fidelity (Li-Fi) is based on “illumination” method for transmitting Data by using Light Emitting Diode’s and reception of data by photo sensor as detector. The objective here is to transmit the audio signal through Light Emitting Diode’s and recover the data using Light Dependent resistor. The Li-Fi is having high speed economical adaptation of Wi-Fi on the basis of visible light communication. Due to its better efficiency over radio base technology it has become an idea of keen interest in past few years. This technology not only increases speed of transmitting data but also increases the Capacity, Bandwidth, Security and reduces cost.This can be easily achieved by colour modulation or intensity modulation thus it can be a good solution of all radio frequency issues.
