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 RX(Visible Light Communication)
- It can receive data 57600 baud rate serialy.
- Distance can be acheived 1 Feet to 10 Feet for wireless open optical communication*.
Applications:
Depends on the LED power.- Indoor wireless open optical communication.
- Indoor navigation.
- Under water visible light communication.
- Smart indoor blind assistive application.
- Vehicle to vehicle communication.
