BI-DIRECTIONAL VISIBLE LIGHT COMMUNICATION FOR INTERNET-OF-THINGS DEVICES

Traditional methods of wireless communications are saturating in terms of data rate, frequency spectrum and reliability. Visible light communications has attracted interests in many fields due to widespread commercial availability of LED lights and partly due to limited bandwidth available on the radio communication. It is even more effective for Internet-of-Things(IoT) devices which require very little bandwidth but still need to remain connected all the time. In this paper, I propose a method for implementing a bi-directional visible light communication system using commercially available LED lights and at the same time, try to achieve flicker free illumination. In this paper, I also go through the range of communication currently achieved with my developed setup with respect to the distance between transmitter and receiver.
