A modified technique for li-fi range extension

Abstract

Li-Fi is a wireless communication technology that utilizes a duplex communication system. It is a kind of visible light communication. Li-Fi employees LEDs which turn on and off at very high rates, thus, transmitting data to a remote receiver. Li-Fi is thought of as an alternative solution to the RF bandwidth limitation problem existing in the Wi-Fi. Although Li-Fi provides and unmatchable data transfer speed over other prevailing technologies, there are few limitations and disadvantages of using it which further attribute to cost, maintenance, range, etc. The paper provides a theoretical method to implement range expansion of Li-Fi devices.
