The internet could become very fast in the near future with the new technology Li-Fi, which has the ability to provide broadband speeds 100 times faster than the widely used Wi-Fi.
A new form of internet data delivery is about to make its way to market, and it could replace Wi-Fi in the coming years. Li-Fi, uses LED-type lamps to send information, and theoretically can offer access to the internet 100 times faster than Wi-Fi.
LED lamps emit visible light light, το οποίο είναι μια σταθερή ροή φωτονίων. Όταν το ρεύμα χειραγωγείται για να δημιουργήσει μικρές διακυμάνσεις, μια device detection can capture the pulses and convert them back into an electrical current, as German physicist Harald Haas stated during a TED Talk. Haas is a professor of mobile communications at the University of Edinburgh and the founder of pureLiFi, a leading company in Li-Fi technology.
The Li-Fi connections use visible light connection (VLC), as we mentioned an Estonian company, Velmenni, who tested the technology, managed to grab the 224 Gbps speed in the lab and 1 Gbps outside.
"Currently, we have designed a smart lighting solution for an industrial environment where data communication takes place through light. "We are also piloting a private company to set up a Li-Fi network for Internet access from office space," Deepak Solanki, CEO of Velmenni, told the International Business Times in the United Kingdom. consumption by the general public could be launched in about three to four years.
The promise of an incredibly fast Internet that gives the Li-Fi will not be something that can happen from one day to the next. Technology and equipment are totally new, so we are talking about a total change in infrastructure and networks.
Another difficulty in this project could be the fact that new technology uses light instead of radio waves, and will not be able to pass through walls, which means that its range will be somewhat more limited. However, it also means that the network will be safer, putting an end to bandwidth theft from neighbors.
Finally, the Li-Fi will not work as well outdoors, as sunlight could disturb its signal.
