Light fidelity (Li-Fi) has recently emerged as a promising solution for wireless communication in hospital environments, offering significantly higher speeds and enhanced security compared to traditional technologies. This research aims to improve data transmission quality in hospitals using Li-Fi technology, by employing multiple sensors that detect clinical parameters such as temperature and pulse. This medical data is securely transmitted via light to ensure efficient and disturbance- free communication. Channel inversion precoding (CIP), a broader term encompassing techniques like Singular Value Decomposition (SVD) precoding, is implemented to further enhance the system’s robustness and efficiency, making Li-Fi superior to conventional methods. The proposed Li-Fi system design is cost-effective and inherently secure, as the reliance on laser light eliminates the risks of interference with medical equipment. This innovation represents a revolution in high-speed and reliable data transmission in healthcare. Evaluate system performance using data rate and packet delivery ratio metrics. The results reveal the superiority of the designed system for remote patient data transfer with minimal interference.
