A popular wireless data transmission technology WiFi is about to become obsolete.

At least that’s indicating the first tests . a new technology, called LIFI, which can transmit data to 1GB per second

This represents a 100 times greater than the current speed WiFi And it can get even faster:. technology company Estonia Velmenni , which conducts these experiments, says that tests performed in laboratories at Oxford University have achieved 22GB per second.

The LIFI technology, short for “Light Fidelity” (Loyalty of Light, in literal translation) uses waves light for transmission, using light emitting diodes (LED).

“We created an intelligent lighting solution for an industrial area in which the data communication takes place through the light. We are also doing a pilot project, creating a network of LIFI to access the internet in the office, “said Deepak Solanki, director general of Velmenni

In 2011, the creator of this technology, the scientist Harald Haas of the University of Edinburgh, showed that with just one LED can transmit more data than a telephone antenna.

The LIFI allows a lamp has two features:. enlighten and ensure connectivity to the router

The technology was presented in 2012 at the Consumer Electronics Show, an international event with technologies for consumption, in Las Vegas. In a demonstration, two smartphones at a distance of 10 m exchanged data with each other by varying the intensity of light from their screens.

It has been shown, too, that the LIFI is more secure than WiFi and does not interfere with other systems, but it could be used without problems on a plane, for example

But there is a drawback:.. light can not pass through walls

But despite its advantages, the new system will not replace the WiFi altogether in the near future.

On the contrary. Both technologies can be used together to create safer and faster networks. And researchers are working on the adaptation of current devices to be compatible with LIFI.

The PureLifi, a company created by Haas and his team, offers an application for secure wireless access.

The French company Oledcomm technology are installing your own LIFI system in hospitals.

At the same time, companies such as Samsung, LG and other electronic devices manufacturers are interested in creating smartphones with light sensors LIFI .
