In this work, a practical wireless optical communication system has been proposed for the purpose of monitoring the health condition of patients who are in hospital operating on the basis of the wireless communication system and fiber sensors. The suggest practical system employ a diffuse optical broadband link technique based on laser Li-Fi the technology, Fiber Bragg grating (FBG) sensors was investigated. The focused on optical fiber sensors (pressure and temperature) for medical applications because it‘s small size, immunity to electromagnetic interferences and their suitability for remote monitoring. Fiber Bragg grating (FBG) based (blood pressure, temperature) sensors is designed and implemented using a conventional laser source, Optisystem version 15. The collected data from sensors is transmitted to main unit, the suggested system tested under different operating conditions such as, optical link distance, laser power and transmitter angles, all operating conditions was successively demonstrated.
