Lifi Technology: Introduction, Applications, Challenges and Security Evaluation

Nowadays, with the widespread use of the Internet, one of the great challenges of communication networks is the access speed. The speed of access becomes a challenge when different devices connect to a wireless network. Wi-Fi networks are facing some problems, such as difficult or impossible connectivity in some places and a speed far below today's needs. In this research, while introducing Li-Fi technology, where the data is exchanged wirelessly through visible light, its features and limitations are studied. The architecture and scientific relations and mathematical models of this new technology are also presented. There are new ideas and applications for the Li-Fi that are explored in this paper and finally, Li-Fi technology is compared to Wi-Fi technology based on various parameters.
