Utilizing a Raspberry Pi for Transmitting Image using Li-Fi Transceiver

Li-Fi technology is one of the emerging fields in the communication domain. When information is transmitted through an LED light, the flickering is faster than the human eye can perceive. The information is transmitted faster using Li-Fi when compared to Wi-Fi. In this paper, we propose a prototype where we use Raspberry Pi to retrieve images stored in it, convert it into bits, and send information using LED. This information is captured by a solar panel and is converted into an image using another Raspberry Pi. We also simulate the process of converting image into bits in the transmission side and converting received bits into an image at the receiver side using Python code. Li-Fi enables us to use a broader light spectrum when compared to the radio spectrum used by Wi-Fi which is crowded. Li-Fi has found its applications in hospitals, schools, and workplaces.
