Image Transmission Using Li-Fi

We went from 56kbps wired ARPANET connections limited to the US military in the 1960s, to unimaginably fast wireless 100 Mbps connections in the 2010s. But what the future holds will certainly blow your mind 1Gbps or more and that is still an understatement LIGHT FIDELITY it is or popularly known as Li-Fi. The two-major prospect being aimed is extension or enhancement of the wireless services and to support the number of the exponentially growing user which the RF spectrum is unable to provide due to a limited spectrum of radio waves. So, Li-fi that is based on the visible light spectrum is being designed. It uses a LED and a photodiode or phototransistor to transmit and receive data respectively. Li-fi can be compared with the existing wireless technology i.e. Wi-Fi in terms of speed and security which the former provides better. The aspiration of this research paper is cunning a prototype of Li-fi transmitter and receiver to transmit data. The schematic design was made using Proteus 8 professional. Software coding was done on C language and PIC microcontroller is used. Successful transfer of image and text were achieved. As a deduction, this work gives an originative way of scheming a Li-Fi Prototype.
