Healthcare Application-Oriented Non-Lambertian Optical Wireless Communications for B5G&6G

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

Frontier Progress of Unmanned Aerial Vehicles Optical Wireless Technologies

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
