The dianetwork it could become very fast in the near future with the new Li-Fi technology, 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 for the Mission information, and theoretically can provide internet access 100 times faster than Wi-Fi.
LED bulbs emit visible light, which is a steady stream of photons. When the current is manipulated to produce small fluctuations, a sensing device can pick up the pulses and convert them back into electric 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.
"Επί του παρόντος, έχουμε σχεδιάσει μια έξυπνη λύση φωτισμού για ένα βιομηχανικό περιβάλλον όπου η επικοινωνία δεδομένων γίνεται μέσα από το φως. Κάνουμε επίσης ένα πιλοτικό έργο με μια ιδιωτική εταιρεία για να δημιουργήσουμε ένα δίκτυο Li-Fi για πρόσβαση στο Διαδίκτυο από τους χώρους γραφείων," ανέφερε ο Deepak Solanki, Διευθύνων Σύμβουλος της Velmenni, στους International Business Times του Ηνωμένου Βασιλείου, σημειώνοντας ότι ένα μοντέλο για κατανάλωση από το ευρύ κοινό θα μπορούσε να λανσαριστεί σε περίπου τρία με τέσσερα χρόνια.
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 with this project could be the fact that the new technology uses light instead of radio waves, and it won't be able to pass through walls, which means its range will be somewhat more limited. However, this also means that the network will be more secure, putting an end to theft bandwidth from neighbors.
Finally, the Li-Fi will not work as well outdoors, as sunlight could disturb its signal.
