2020: Aqua-Fi: the underwater Wi-Fi working with use of LEDs and lasers is developed

The Internet is the irreplaceable communication medium connecting tens of billions of devices worldwide and in 2020, there was a technology which allows to use the Internet under water.

People both from scientific community, and from the industry want to trace and investigate the underwater environment in details. The wireless internet in the sea will allow divers to communicate without signals hands and to send live data to a surface Basem Shikhada, the researcher from the university of Science and Technologies of the King Abdullah

Underwater communication is possible radio - audible and light signals. However radio can transfer data only to short distances while audible tones can be used on long distances, but with very restricted speed of data transmission. The visible light can far extend and bear many data, but narrow light beams require the accurate line of the overview between transmitters and receivers. Now the Basema Shikhada command created the underwater wireless Aqua-Fi system which supports Internet services, such as sending multimedia messages using LEDs or lasers. LEDs provide low power consumption for communication on short distances while lasers can transfer data further, but they need more energy.

In a prototype of Aqua-Fi green LEDs or the laser on 520 nanometers for sending data from the small computer under water on light detector connected to other computer by the boat were used. The first computer will transform photos and videos in a series of units and zero which turn into light beams, switchings happen to very high speed. The detector of light will recognize this change and returns back it in the sequence of bit of information which the accepting computer will transform back to initial material.

Researchers tested a system, at the same time unloading and loading multimedia between two computers located at distance of several meters in static water. They recorded the maximum speed of data transmission 2.11 megabytes per second and average delay in 1 millisecond for transfer there and back.

It is the first time when someone used the Internet under water completely without wires Basem Shikhada

In the real world of Aqua-Fi will use radio waves for sending data from the diver's smartphone on the "lock" device connected to its equipment. Then, just as the home Internet router, this gateway will transfer data with the help of a light beam to the computer located on a surface, connected to the Internet via the satellite. Before commercial starts, creators need to overcome the difficulties connected with beam alignment between the receiver and the transmitter for what they are going to use receivers of spherical shape.

We created rather cheap and flexible method of connection in the underwater environment to a global network the Internet. We hope that Aqua-Fi will be used under water the same as Wi-Fi over water Basem Shikhada
