Underwater Wi-Fi was the first successful test

Подводный Wi-Fi прошел первые успешные испытания

Experts believe that the new wireless Internet access system, which sends signals via beams of light, could trigger a revolution in the field of communication.

A new technology called “Aqua-Fi”. It was designed to ensure that divers could transmit video and data to the surface or obshatsa under water not only hand gestures.

“This is the first time when someone used the Internet under water through a completely wireless connection,” said study author Professor Basem of Sihara.

“People from academia and industry want to monitor and explore the underwater environment in detail”, – he explained.

Aqua-Fi uses radio waves to send data from your smartphone diver on a Raspberry Pi computer attached to the equipment on his back. In turn, the computer sends photo, video, and data with the help of beam of light computer on the surface, which is connected to the Internet via satellite. This is similar to how Wi-Fi booster extends the coverage of a home router. Except for the light, the underwater connection is possible with the help of radio waves and acoustic signals. But each method has limitations.

For example, a radio wave can transmit data over short distances. The acoustic signals can provide a link at greater depths, but with very low speed. In turn, visible light is able to deliver large amounts of data with great depth. However, it requires maintaining a clear visible line between the transmitter and the receiver. Scientists say a new method of Aqua-Fi combines a radio and light signals.

During the test they were loaded to a device under water and on the surface of the media files. The transfer was carried out between two computers located on a few meters apart in calm water. The maximum transfer rate during the test reached 2.11 Megabits per second.
