Li-fi, the alternative to WiFi and 5G which transmits data on visible light, can reach speeds that are 100 times higher than that of the current Wi-Fi networks. The technology is now tested for the first in a commercial context, and would be ready in a few years for the mass market.
Li-fi, a high-speed alternative to wifi, leaves the lab environment and is now being tried out in real life. Estonian start-up Velmenni is the standard testing in corporate environments and on industrial sites in and around the capital Tallinn.
100 times faster than current Wi-Fi networks
The li-fi technology allows speeds up to 1 Gbps, which is 100 times more than the current Wi-Fi networks. At these speeds, you could download a full movie in high definition a matter of seconds.
It is striking that li-fi visible light is used to send data over (visible light communication or VLC). The standard, which was first proposed in 2011 by Professor Harald Haas of the University of Edinburgh, would be ‘safer’ than traditional WiFi, partly because light rays remain local and not, for example can radiate through a wall.
224 Gbps
In lab environments, researchers have now besides all speeds up to 224 Gbps can record, which immediately indicates the potential of the technology.
“We are currently conducting tests with the VLC technology in various sectors, “said CEO Deepak Solanki recently at the Slush conference in Helsinki. “We have developed a smart lighting solution that can be used in an industrial setting, and we have a pilot project to deploy at one of our customers while we roll out a li-fi network in their offices.”
More effective and faster networks
Although li-fi may not be suitable for wifi to be replaced completely, the technology may be used in combination with its slower ‘pastor’, so as to get more efficient and faster networks. Depending on how the current pilot projects expired, the LIFI technology which Solanki could be deployed within three to four years for consumers. They could then default on their lights at home “consume”.
The problem is that there are currently no devices on the market that also support li-fi. “A completely new li-fi-ready infrastructure should be deployed,” realizes the CEO, “we would have to devise a system that can be integrated into current Wi-Fi networks.”
LED lamps
Inventor Harald Haas has however already made it clear that soon will be able to use all LED lights as a quick alternative to wifi. In a recent TED talk he threw that today’s LED infrastructure is best suited for li-fi.
“The only thing we have to do is add a small microchip to every lighting element, and may from then lamps and provide lighting, and in data transmission. “
