Subaqueous Information Transmission Based On Li-Fi Technology

Abstract

The present paper relates to “Subaqueous Information Transmission based on Li-Fi Technology”. Currently white boards are used by divers to communicate with each other, which is very problematic task. In this paper a model for providing assistance to divers is proposed that uses light sources to transmit the information. “Light Fidelity (Li-Fi) is a bidirectional, high speed and fully networked wireless optical communication”. Even if the light is blocked by a floating object, it is reflected or refracted by widening the angle, resulting in increased ability to reach the receiver section and if the light oscillates, the current still appropriate. There are two sections; a transmitter section, and a receiver section, wherein an audio signal transmitted by the diver passes through the transmitter which converts the audio signal into stream of light beam. The light beam is received at the receiver side and then converted into an audio signal again with the help of various components like PLL, photo detector, amplifiers, speaker etc.
