Measurement-based Close-in Path Loss Modeling with Diffraction for Rural Long-distance Communications
This research demonstrates that the newly developed CI path loss models incorporating a diffraction component significantly reduce standard deviations (STD) and are independent of frequency, especially for LOS beyond the first meter of propagation, making them suitable for use with frequencies up to a millimeter-wave.
Free-Space Optical Communications for 6G Wireless Networks: Challenges, Opportunities, and Prototype Validation
In this study, we perform video signal transmissions via an FPGA-based FSO communication prototype to investigate the feasibility of an FSO link with a distance of up to 20~km.
RF Lens Antenna Array-Based One-Shot Coarse Pointing for Hybrid RF/FSO Communications
Because of its high directivity, free-space optical (FSO) communication offers a number of advantages.
An Energy-efficient Aerial Backhaul System with Reconfigurable Intelligent Surface
In this paper, we propose a novel wireless architecture, mounted on a high-altitude aerial platform, which is enabled by reconfigurable intelligent surface (RIS).
