Li-Fi Technology Presentation
What is Lifi?
LI-FI is the transmission of data through illumination, sending data through a LED light bulb that varies intensity faster than the human eye can follow.
Li-Fi is bidirectional, high speed and fully networked wireless communications similar to Wi-Fi. Li-Fi is a subset of optical wireless communication (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting.

Introduction of Lifi technology
What is Li-Fi?
Why is it required?
Li-Fi Vs Wi-Fi
lifi working process?
Operational procedure is very simple, if the led is on, you transmit a digital 1, if it’s off you transmit a 0. The LEDs can be switched on and off very quickly, which gives nice opportunities for transmitting data. Hence all that we required is some LEDs and a controller that code data into those LEDs.
