Li-Fi is 100 times faster than Wi-Fi in transmitting data




A new wireless technology has just been taken and tested out of the lab which has been reported to be able to transmit data as fast as 1GB per second — about a hundred times faster against our standards for today’s Wi-Fi speeds.

Li-Fi is able to send this much data by using VLC technology (visible light communication, not the media player software). It was invented in 2011 by Herald Haas after being able to send significant amounts of data from simply flickering a single LED compared to what a cellular tower could transmit. Back then, he was able to record a chart-topping 224 gigabits per second of data. For comparison, ScienceAlert puts it as downloading 18 movies of 1.5GB each every second.

“Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light. We are also doing a pilot project with a private client where we are setting up a Li-Fi network to access the Internet in their office space.”

And now this same principle was used in offices as an initial trial in real-life situations. Haas mentions that all that needs to be done is to place a microchip to every potential illumination device and this would give it dual functionalities — illumination and wireless data transfer.

By rapidly flicking these specially-designed LEDs on and off, it could send specific messages in binary code that could then be retrieved and decoded by devices. Rest assured that these flickering of light is done at extreme speeds that make it invisible to the human eye.

There are a lot more interesting things to learn from Li-Fi (like being more secure and efficient, for example) which you can read here.

If the tests continue to succeed, there’s a bright chance (pun intended) that we’ll be using LEDs not only to light up our homes but also to connect to the Internet.

    Another reason kung bakit “Dapat laging bukas ang ilaw.” hahaha corny.

    That’s what you call a “bright” idea =)

      GI (genuine ilocanos) are said to be clannish, i.e. solid north. Now if “BB” gets 85% of the geographical North +
      80% of the GIs in diaspora, baka dina “mahirap implement”, what with 5 VP candidates.

    There should be an infrared version (or is there already?) of the lifi. Para kung ayaw mo ng maliwanag like if you’re doing something while browsing /streaming. Lol
