Li-Fi: A Full-Fledged Wireless Communication Technology

S. D. Fabiyi

Abstract: Li-Fi, an acronym for light fidelity, is a new wireless communication technology put forward by Harald Haas from the University of Edinburgh. Until the evolution of Li-Fi, Wi-Fi (wireless fidelity) has been tipped by experts to be a potential replacement for cabled-communication. However, Wi-Fi has fallen short of this expectation due to certain loopholes and limitations. This paper presents Li-Fi as a technology which has given wireless communication a broad edge over its wired counterpart. Li-Fi was extensively compared with Wi-Fi. Key advantages of Li-Fi over Wi-Fi were highlighted. Some of the applications of Li-Fi identified include vehicular communication system, underwater communication, internet of things (IOT), smarter power plants, pipeline monitoring and green information technology. It has been projected that by 2018, Li-Fi technology market will reach $6, 138.02 million. Due to its capability to provide a relatively easier, cheaper, faster and more secure communication, Li-Fi has been branded as a cutting edge technology with a prospect of replacing Wi-Fi. Li-Fi is a full-fledged wireless communication technology that leaves users with no room for any excuse to resort to the outdating cabled-communication.
