In the context of healthcare monitoring, it is necessary to transmit vital information from the patient to an interface managed by the hospital staff. In this paper, the authors consider a system in which a patient can move within a hospital room and the data collected by sensors are transmitted to a distant receiver placed on the ceiling. The authors investigate the potentiality of using infrared communications for the transmission of information in this mobile context, by considering the simplest modulation scheme based on On-Off Keying (OOK) technique. In order to represent patient mobility in the room, the authors use a model for the patient location based on a Gaussian distribution over the three axes of mobility in the room. In addition, they consider different scenarios, considering either a Line Of Sight (LOS) configuration or a diffuse one. From the obtained results, the authors can determine by evaluating the transmission probability of outage, the potentiality of this technology to ensure the communication between sensors and the collecting point.
