Li-Fi Technology

Introducing the fast mobile internet connectivity,Li-Fi .
Light Fidelity (Li-Fi) is similar to Wireless Fidelity(Wi-Fi) but using light waves instead of radio waves.Concept developed by Harald Haas, a professor at Edinburgh university.Light waves are implemented using LED bulbs, hence providing a low cost , efficient and faster mobile internet connectivity than existing Wi-Fi.

          Talking more technically, this concept transmit data through illumination of LED bulbs and this illumination intensity vary swiftly.Light varying the rate by LEDs flicker(on/off) produce a string of Os and1s making a good ease encoding.Visible light part of spectrum is used,thus earned another name Visible Light Communication (VLC) An array of LEDs are used for transmission,hence a fast parallel data transmission is provided.

         Li-Fi don't even compensate on their security. They provide relative high secure transmission.Unlike radio waves,light waves don't interfere with other radio equipment in nuclear plants and planes.They even can use underwater without any disturbance.

The alternate Wi-Fi is the future mobile internet
