In Wireless communication, Wi-Fi is the most versatile and effective technology which compact with radio frequencies for data transmission. But because of multiple accesses, Wi-Fi is facing many challenges namely capacity, availability, efficiency and security. The Wi-Fi emits radio waves which are very harmful to the patients and the radio waves interpret the medical instruments. This paper focuses on developing a light fidelity (Li-Fi) based system and analyzing its performance. This protocol can be adapted where radio waves are restricted, such as in airplane hospitals, and in some research facilities. Noticeable Light Communication (VLC) has increased extraordinary enthusiasm for the most recent decade because of the quick improvements in Light Emitting Diodes (LEDs) manufacture Li-Fi is a novel technology for high-density wireless data transfer relieving no radio interferences in confined areas so it can be used in biosensors to measure various health parameters. This technology envisions a future where data for laptops, smartphones, and tablets will be transmitted in an economic and eco-friendly medium of light in the room.
