Designing and Simulation of Hardware Based Light Signal Transference in Visible Light Communication

Abstract

As RF spectrum is shrinking in terms of its capacity and Bandwidth, the visible light communication (VLC) is the innovative solution to mitigate the insurmountable of the spectrum. For indoor communication, the VLC is the energy efficient green technology which offers budget savings and carbon reductions having numerous advantages. It uses LEDs which is already existing lighting infrastructure that can be re-used. In this the optical energy of LEDs is modulated using IM/DD technique. Li-Fi stands for light fidelity which is 5G wireless optical networking system in which the signal is encoded in the form of strings bit’s 1’s and 0’s. It is a high-speed network which utilizes visible light communication of the electro-magnetic spectrum in which LEDs are used; which acts as a source of transmitter. Here, we have designed and implemented a Li-Fi model using hardware and simulation software using solar cell and live results can be observed and calculated. The design is based on the possibility of transmission of light in the visible light communication (VLC) of a signal using solar cell. The solar cell or photo voltaic cell is very sensitive to the light energy and gives photocurrent of high intensity. The testing of the circuit is done by using Every Circuit simulation software in which we have designed each section of the model and then interfaced to verify the results.
