What exactly is LiFi?


WiFi runs our life. In fact, according to a survey carried out by Direct Line by Opinium Research online, it is the number one thing that their respondents couldn’t live without. But no matter where you are in the world, you’ve probably experienced internet connectivity problems at one point or another.

Enter LiFi, a type of wireless connection that can be up to 100 times faster than WiFi.

Imagine a world where you can connect to high-speed internet by just flicking on your light switch. LiFi is a wireless optical networking technology that uses LEDs for data transmission. In simpler terms, LiFi is considered to be as a light-based WiFi which uses light instead of radio waves to transmit information. Using light to transmit data allows LiFi to deliver a couple of advantages such as working in areas susceptible to electromagnetic interference like hospitals and aircraft cabins and working across higher bandwidth while offering higher transmission speeds.

The LiFi technology is currently being developed by numerous organizations around the world.

How does LiFi work?

LiFi is a Visible Light Communications system transmitting wireless internet communications at very high speeds. The technology makes a LED light bulb emit pulses of light that are undetectable to the human eye and within those emitted pulses, data can travel to and from receivers. Then, the receivers collect information and interpret the transmitted data. This is conceptually similar to decoding Morse code but in a much faster rate – millions times a second. LiFi transmission speeds can go over 100 Gbps, 14 times faster than WiGig, also known as the world’s fastest WiFi.

    1. The stores have mostly cleared out their inventories of incandescent bulbs. Can’t seem to find anything but LED and fluorescent. What you do find are the shortest lasting light bulbs I’ve seen in my numerous years!
      My Grandma had a clear bulb in her front closet that came on with a pressure switch. It fascinated me, but my dad chased me away from playing with the door, saying that bulb had been there since the 40’s, which was 20 years plus, at that time!
      Truly, things aren’t made like they used to be.
