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 basic working principles, challenges and applications with comparison of Wi-Fi technology. The comparative study is also presented the features of both technologies.
