Review Analysis of Li-Fi (Light fidelity) Technology

Abstract

Li fi is very rapidly emerging and bright wireless technology in field of data communication. It offers a genuine and very efficient alternative to radio-based wireless systems. This technology give better solution on problem such as the shortage of radio-frequency bandwidth and also allow internet where traditional radio based wireless isn‘t allowed like aircraft. The wireless internet service is offered to the people through latest technologies in commercial and industries. Most of them are based on radio waves in the spectrum. These waves are very harmful to the diseased people and in signal sensitive areas. Hence it could not be utilized in such environments. To overcome these limitations, Li-Fi is the technology which is created to work in these environments. This technology provides transmission of data through illumination by sending data through LED. This paper deals with the overview of Li-Fi technology, its working principle, and applications of Li-Fi. The comparative study of the features of other technologies with Li-Fi is also taken into consideration.
