Few Words About Us
Li-Fi, formally known as Visible Light Communication, is a portmanteau of “Light” and “Wi-Fi”.
It relies on using visible light for transmission of data, instead of radio waves, which are used in the conventional Wi-Fi system.
As a cutting-edge technology, it is now finding its place throughout the globe in various applications,
both research and industrial alike; mostly due to its economical feasibility, immense scalability and supreme efficiency.
Our project, albeit preliminary, is a comprehensive proof of concept,
with optimized circuitry and an elaborate communication protocol implemented in unison to successfully demonstrate the transfer of various types of files (.txt, .jpg, .pdf, etc) at an unforeseen speed.

Our Technical Achievements
Initial Stages
In the initial stages of the project we tried and tested a large number of procedures, processes, components and circuit-designs. Since, this is a growing field in which a lot of research is under progress, we came across a few papers and open-source projects, however, none could help us out. Thus, we embarked on our journey to implement everything from scratch.
Hardware Development
The first true milestone was when we were able to generate square wave-forms on both sides which enabled us to accurately transfer encoded data from transmitter to receiver. And hence, the first working prototype for Li-Fi was on its way.
Custom File Protocol
We had initially started with implementing a one-way system for transmitting a string from one device to another. Currently we are using our FTP2.0 which has an acknowledgement system and supports two-way communication. It is capable of transferring files of any format.
Development of a Working Prototype
After we developed the Custom File Transfer Protocol v2, we turned our attention to testing and optimizations which resulted in a complete working prototype which, in its initial stages itself, allowed file transfer at a speed of 400bps and over a distance of 15cm and was successfully tested with several files and 0% data corruption was observed.
Attainment of speed of 2kbps
Thanks to the upgrades in our hardware and optimization of out software logic, we were able to achieve the above mentioned speed of 2kbps.
Attainment of a distance of 1ft
With the development of a custom LED panel we have been able to increase the distance of transmission to 1ft.
