Data Transmission through Li-Fi

Abstract

Three decades after the first commercially-available mobile communication system were first presented, wireless communication has become an essential product such as electricity & gas. The dramatic increment in mobile data traffic in the last couple of decades has incited the gigantic distribution of wireless systems. Hence, we have seen copious warnings of a looming "RF spectrum crisis” [1] because versatile data requirements are increasing exponentially while system spectral efficiency saturates in spite of newly offered gauges and unbelievable innovative developments in this field [2]. Most recently, VLC has been distinguished as a possible answer for moderating an approaching RF spectrum emergency. Presently, WiFi is the fundamental wireless communication medium which utilizes radio waves and is utilized everywhere, for example, workplaces, schools, homes, universities, colleges and so on. Be that as it may, the fundamental issues of Wi-Fi are shortage of radio waves, constant exhaustion of data transfer capacity, RF impedances, cost of transmission capacity and the utilization of repeaters. Different parts of electromagnetic spectrum incorporate X-beams, Gamma beams and Ultraviolet lights yet they are not good for wireless communication as they are risky for human body. Other than the said issues because of broad use the radio recurrence waves are getting blocked and the limit is diminishing. So as to beat this trouble in future, light fidelity (Li-Fi) technology was concocted in 2011 by Dr. Herald Haas which does not transmit the data through radio waves but rather through visible light.
