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)
