What is LiFi?
LiFi (Light Fidelity) is a game changing light-based communication technology that uses light waves instead of radio technology to deliver data. LiFi is a high speed, fully networked wireless communication technology that is 100 times faster than WiFi.
How It Works:
Using light to transmit data is nothing new; we see it in fiber-optic cables and point-to-point links, but LiFi offers a special combinations of technologies that allow it to be used for ultra-high speed internet communications using normal light frequencies across the 440 to 770 terahertz (THz) spectrum. This technology can also be used in non-visible frequencies like infrared, X-ray and ultra-violet frequencies which gives an endless amount of opportunities for Li-Fi to be used and adopted very quickly.
Facts about this new technology:
Facts about this new technology:
- LiFi uses visible light vs. Wi-Fi using radio waves. This means no bulky cell towers; thus eliminating the downfalls with limited range of radio waves.
- LiFi is already used in some smartphone cameras. Apple has used this technology in versions of the iphone, iOS9.1 and up.
- LiFi is Hack Proof. Since light cannot penetrate through walls, it is difficult to steal personal data. So this is a more secure alternative to Wi-Fi as the available data is confined to a room.
- LiFi can be used where WiFi cannot. This technology can be used from in- flight internet access to hospital setting and elsewhere without adverse effects.
