With the continuous improvement of user communication requirements and the rapid development of information services, optical wireless communication (OWC), which has unlimited bandwidth and precise positioning, is widely used in indoor scenes such as healthcare. For healthcare monitoring application, the optical wireless (OW) link using non-Lambertian emission pattern is investigated in the typical mobility scenario. Numerical results show that the potential gain could been provided by the concerned emission pattern to the OW performance uniformity.

With the continuous maturity of unmanned aerial vehicles (UAV) in materials, communications, and other related technologies, the UAV industry has developed rapidly in recent years. In order to cope with the diversified emerging business forms, the explosive growth of the scale of data traffic, number of terminal connections, high reliability, low-latency, and high transmission rate provided by the fifth generation (5G) network will inject new vitality into the development of the UAVs industry. In this paper, optical wireless technology is introduced into the UAV platform, combining theory with practical applications. We explain many research advances and key technologies in the four aspects of “air, space, earth, and sea” to achieve a strong and broadband communication link. This discussion focuses on link modeling, parameter optimization, experimental testing, and the status quo of UAVs in different application scenarios with optical wireless link configurations. At the same time, based on the current situation of UAV optical wireless technology, the technical problems and the research direction in the future are also discussed.

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.
