Abstract:
Li-Fi stands for lights fidelity. Li-Fi is the transmission of the of data through illumination provide data transmission through a LED light bulb that varies its intensity faster than uman eye can follow. Li-Fi uses light spectrum then radio spectrum. In future an LED can form optical communication system rather than just illuminating. Li-Fi is innovative wireless communication technology which uses light spectrum range from 400-800 THz. Li-Fi offer high bandwidth immunity other than electromagnetic sources provide high level of security and low energy consumption Li-Fi can work in underwater where Wi-Fi does not able to do work Underwater communication is mostly done with the help of RF and Acoustic technique. These techniques have less precision accuracy and low data rate. There is always a risk of divers working inside the water. These underwater scuba divers are highly skilled labors, so the safety of these divers is much premium. Due to the lack of communication between scuba divers and coordinator there is always a risk. So, there is a need of technology to communicate underwater accurately. Underwater communications system utilizing visible light communication (VLC) technology will be ideal for military and scuba divers operating under vessels allowing communication within the light spectrum to a certain distance. We use Laser lights as another light source because it is highly directional and hence more range. Our prime goal is to create a network between scuba divers and Oil Rig to ensure divers safety. This project is prototype having following features Text communication between oil rig coordinator and scuba diver, audio transceiver and aquatic creatures’ detection
