Li Fi (Visible Light Communication)

Overview : 

At the heart of this technology, a new generation of high-brightness light-emitting diodes. Very simply, if the LED is ON, user can transmit a digital string of 1, if it’s OFF then user can transmit a string of 0. It canbe switched ON and OFF very quickly, which gives instant opportunity for transmitting data. It is possible to encode data in the light by varying the rate at which the LEDs flicker ON and OFF to pass differentstrings of 1s and 0s. The modulation is so fast that the human eye doesn’t notice. There are over 14 billion light bulbs used across the world, which needs to be replaced with LEDs 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.
• High quality PCB FR4 Grade with FPT Certified.

Li Fi (Visible Light Communication) Applications:

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