A critical review on Li-Fi technology and its future applications

Abstract

Lifi technology was introduced to face the increased demand of wireless applications caused by the drastic increase of users. Light from LEDs are used to transmit the signals. Unlike radio waves, the data transmission using visible light is more efficient with high security defense. Visible light can be used for free of cost is another major reason for its wide application. There is an increase in the usage of Lifi technology in hospital zones and security communications for its un harmful and data security reasons. Communication domain estimates a high increase in demand for Lifi technology in the near future which includes its usage in space and under water communications. Due to few limitations in Lifi technology; it cannot fully replace radio wave transmission technology. Anyway the hybrid model of bringing both wifi and Lifi technology is having a great future demand in the communication world. This review helps the Researchers in Lifi technology to expand their search in this communication technology.
