There is now a lot of active research being done on underwater sensor networks and communications. In order to try
high-speed communication, the bandwidth and network speed will need to increase. Divers use white boards to communicate because it is exceedingly challenging to do so underwater. However, today's incredible Li-Fi technology, which employs light to enable underwater communication, makes this conceivable. Visible light communication (VLC) systems using light emitting diodes or laser as a medium to high-speed communication are referred to as Li-Fi or Light Fidelity. The photo sensors that serve as the receiver and the transmitter in the LI-FI system are lasers. By altering the rate at which the LASER flickers on and off very quickly to produce different strings, it is feasible to encrypt data in the light as 1s and 0s.
The astonishing Li-Fi concept, put forth by German physicist Harald Hass, uses light to enable underwater communication. Bidirectional, fast, fully networked wireless optical communiction is known a Light Fedelity (Li-Fi). By enlarging the angle, light will be reflected even when it is blocked by floating objects, increasing its capacity to reach the receiver and making it sufficient even when the light moves the current. There are countless applications for Li-Fi. The Navy improves submarine communication systems by using Li-Fi. Future Li-Fi applications might by used for much more than merely in chemical plants, aeroplanes and the ocean.
