A Estonian company Velmenni has developed a new technology, called Li-Fi, using ‘visible spectrum’ instead of radio waves, used in Wi-Fi for transporting data.
According to the CEO of the company, Deepak Solanki, the new technology delivers data a whopping 100 times faster than Wi-Fi, which could potentially pave the way for newer, as yet unheard leaps and bounds in all sorts of spheres, be they computing, entertainment, education, and what have you.
The technology has so far been tested in a working office environment with great success, and should be available to consumers within 3 to 4 years according to Solanki.
What remains to be sorted out is that unlike W-Fi, Li-Fi cannot be used in sunlight (as obviously the Sun’s rays would severely interefere with the Li-Fi signals), and also that it cannot penentrate walls, but still could be used in spaces where Wi-Fi signals cause interference, like aboard aircraft, and in hospitals, and other places where sensitive electronics are used.
The technology was originally mooted by a Professor from Edinburgh University, UK, who demonstrated ist’s use by streaming a video using a LED source.
