Underwater Communications System

There is currently a challenge for effective underwater wireless communications due to RF absorption loss, making Wi-Fi an inefficient method of communication in underwater situations. Current systems still lend themselves to physical hand signals or fixed cables.

Once developed, an underwater communications system utilising 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 radius via an audio system built into their diving suits.
