Survey and challenges of Li-Fi with comparison of Wi-Fi

Abstract

The wireless internet service is offered to the people through Wi-Fi technology in commercial and industries. It is working based on radio waves in the spectrum. These waves are very harmful to the diseased people, signal sensitive areas. Hence it could not be utilized in environments such as hospitals, scan centers, air lines etc. To overcome these limitations, Li-Fi is the technology that is developed to work in such environments. This paper is presented the study of Li-Fi technology, working principles, challenges and applications with comparison of Wi-Fi technology. The comparative study is also presented the features of both technologies. The observations show that Li-Fi performs harmless data transmission at high speed using light source.
