In this article, a multiband channel characterization at sub-THz is presented, based on three measurement campaigns conducted in an indoor environment. Different frequency ranges were explored, and LOS and NLOS propagation scenarios were considered. The article focuses on the extraction of omnidirectional power angular delay profile from directional measurements and presents modeling and cluster study of large-scale parameters.
In this article, we present a multiband channel characterization at sub-THz. Three measurement campaigns were conducted in an indoor environment, for different frequency ranges: 125-155, 235-265, and 270-300 GHz, by exploiting a single (vertical) polarization antenna and performing only the azimuth plane. Line-of-sight (LOS) and nonline-of-sight (NLOS), given by human body obstructions and walls, are considered. From directional measurements, the omnidirectional power angular delay profile was extracted. Modeling of large-scale parameters and cluster study are presented.
