Visible light communication has more bandwidth capacity, inexpensive and procured optical version of Wireless fidelity technology and also it can be regarded as Li-Fi ( wifi based on light ). Li-Fi uses luminous lamps i.e. LEDs on transmitter end which is responsible for lighting a room as well as transmit information in digital form. The working of the Li-Fi module is not as complex as Wi-Fi. It uses the basic concept of transmission of signals where logic 1 represents the data transmission and logic 0 represents no data transmission. The system proposed here is built to develop the most prominent and suitable VLC transceiver system for Healthcare. The various combinations used and transmitter and receiver end ensure an appropriate system to transfer critical parameters of a patient in the hospital environment. The patient monitoring using the Li-Fi is done with the help of various sensors and series of permutations of components used at transmission and reception side. Wifi is quite popular and is present in most of the working environment it can cause interference in the working working of other devices whereas LiFi which is present in the visible EM spectrum will not lead to any interference issues in other devices. LiFi’s bandwidth is unlicensed hence it is cheap, faster, more secure and has huge capacity transmission.
