A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.
Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).
“We’re now carrying out a few pilot jobs within different companies where we can employ the VLC (visible light interaction) technology”, Deepak Solanki, CEO of Estonian tech firm, Velmenni, advised.
Specialists, however, do not believe that this may phaseout Wifi. Radio signals need permissions and were limited, and thus the LED light technology could be explored.
Li-Fi being both a faster and cheaper solution to transmitting data Though I can't see it actually being as accessible as Wi-Fi.
It's more or less a Ethernet contender at the moment by the looks of it, because you'll either have to have the receiver and the device stationary (which I guess slays for desktop PC's) or you'll have to make devices that can read the signals and submerge the entire planet under multiple lamps which obviously isn't going to happen. Also ambient lighting is a huge factor.
