摘要：In this paper, indoor optical wireless system using Infrared (IR) technology is developed for healthcare monitoring. This to insure the reliability, the security and the mobility of the patient during his/her stay in hospital. Various studies were performed to develop a mobile optical wireless system but using celling bounce model which considers just one reflection and the transmitter has to be pointed to the ground which limits the patient�s mobility and movements. In this research, we consider an optical source (LED) coupled with the medical sensor and can randomly change its position within the xy-dimensions of the room and within height varying from 0 to 1.3 m which is the average height of the medical sensor to be put on the body. While the receiver is located on the centre of the ceiling. The line of sight and diffuse propagation links are considered to investigate the capability of the developed system to transmit the health information of the patient to the receiver after undergoing multiple reflections from different walls and objects placed in the room. Using MATLB simulation, the average received power, RMS delay spread, SNR and BER are calculated in order to evaluate the performance and capability of the system with LOS, first and second order reflections for all positions that patient can reach to.
