Office Room Channel Modeling and Object Attenuation at Sub-THz Frequencies

Large bandwidths are needed to meet the high-throughput requirements of future wireless communication systems. These larger available at mmWave and sub-THz frequencies, such as V-band ranging from 50 75 GHz D-band 110 170 GHz. In this paper, we present channel measurements in an office environment, covering full D-band. Line-of-Sight (LOS) path loss (PL) is modeled a function frequency distance. Both single-frequency floating-intercept multi-frequency alpha-beta-gamma model provide good fit measured LOS PL data. Attenuation due blockage by various desk objects, computer peripherals cables, determined, well attenuation plant obstructions. obstructed ranges 3 dB for single universal serial bus (USB) cable, up 25 laptop power supply, mouse, monitor, or plant. Because higher diffraction angle, when distance between antennas decreases. We measure around monitor dual polarization verify whether via reflected non makes possible blocked.
