Li Fi (Visible Light Communication)

Overview

At the heart of this technology is a new generation of high-brightness light-emitting diodes” .”Very simply, if the LED is on, you transmit a digital 1, if it’s off you transmit a 0. They can be switched on and off very quickly, which gives nice opportunities for transmitting data.It is possible to encode data in the light by varying the rate at which the LEDs flicker on an off to give different strings of 1s and 0s. The modulation is so fast that the human eye doesn’t notice.There are over 14 billion light bulbs worldwide, they just need to be replaced with LED ones that transmit data.

Li Fi (Visible Light Communication)

Features:

• It can transmit data 57600 baud rate serialy.
• Distance can be acheived 1 Feet to 10 Feet for wireless open optical communication*.
•  High intensity LED matrix.

Applications:

• Indoor wireless open optical communication.
• Indoor navigation.
• Under water visible light communication.
• Smart indoor blind assistive application.
• Vehicle to vehicle communication.

*Depends on the LED power.
Application Note:

• Li-Fi based indoor navigation system.
• Li-Fi based communication system.
• Li-Fi based indoor blind navigation system
