World’s First Underwater WiFi is Set Up

Now, a new study shows that a type of aquatic internet can send data through light beams to allow divers to instantly stream footage from under the sea to the surface.

With our current technology, divers use hand signals, radio, or acoustic or digital light signals to communicate. While these allow fairly effective communication, they have their limitations. 

In order to help provide a solution, Shihada’s team, from King Abdullah University of Science and Technology in Saudi Arabia, built an underwater wireless system that they’ve dubbed Aqua-Fi. 

Aqua-Fi supports internet services, such as multimedia message sending via either LEDs or lasers. The LEDs provide a low-energy short-distance communication option, while lasers need more power but can carry data further.
