Underwater WiFi Developed Using Aqua-Fi, Led and Laser

Thanks to Aqua-Fi technology, underwater divers and ships on the water will be able to send data with laser beams.

Developed with wireless optical networks, Aqua-Fi uses radio waves to send data from a divers’ smartphone to a “gateway” device connected to a Raspberry pi.

The diver sends the obtained data via a light beam to a computer on the surface connected to the internet via satellite. The internet, which sends data with light services, enables divers to instantly transfer images from the sea to the surface.

Internet, which connects billions of devices in the world, is now under a great effort to connect to the Internet. It has been an indispensable communication tool in the world’s age.

Basem Shihada said, “People from both academia and industry want to watch and explore their underwater environments in detail. The underwater wireless internet will allow divers to speak without hand signals and send live data to the surface ”.

Its underwater communication has been made possible by radio, acoustic and light signals. While the radio can only carry data over a short distance, its acoustic signals can carry a limited number of data over a long distance. Light signals, on the other hand, can carry great distances and lots of data, but narrow light signals must have a clear line of sight between transmitters and receivers.

Shihada’s team built Aqua-Fi, an underwater wireless system that supports internet services and sending multimedia messages using LEDs or lasers. While LEDs offer a low-energy option for short-distance communication, lasers can carry more data but require more power.

Using an aquatic internet service, scuba divers can send shots of marine life in real-time. The prototype was made using green LEDs and a 520-nanometer laser. They used the light detector to send data from a simple computer to another computer. It converts light signals into 1s and 0s series. The light detector detects this variation and returns it to the 1s and 0s values that the receiving computer converts to the original shot.

Aqua-Fi Prototype Work
In the water, they tested the system by uploading and downloading multimedia between two computers at a distance of a few meters at the same time.

They recorded a maximum data transfer rate of 2.11 megabytes per second and an average latency of 1.00 milliseconds for a round trip.

-Uses radio waves to intelligently send data to a diver’s device through the Aqua-Fi gateway.

Like a booster that extends the WiFi range, this gateway sends data via a light beam via satellite to a computer on the internet-connected surface.

The light beam must also be perfectly aligned with the receiver in moving waters, and the crew must be a spherical receiver capable of capturing light from all angles.

It should be a relatively inexpensive and flexible way to connect underwater environments to the global internet.

The company hopes one day that Aqua-Fi will be widely used underwater as well as above water of WiFi.
