This study analyzes the omnidirectional power delay profile (PDP) characteristics at the 105 GHz band in a personal office desktop area by conducting a multipath propagation measurement. In those days, for the 6th generation communication system, there is a demand for a wider bandwidth, and exploring sub-terahertz (sub-THz) is attracting huge interest. However, the omnidirectional multipath propagation characteristics at the 105 GHz band for a personal desktop environment has not been investigated yet regardless of the potential feasibility of the wireless personal area network (WPAN) communication systems operating at this band in a personal desktop area. In this study, we first conduct a measurement of omnidirectional PDPs for the 105 GHz and 60 GHz bands in a personal desktop environment. The comparison of these two bands unveils an affinity in terms of delay-domain multipath characteristics, where the delay spread difference is less than 1 ns. Moreover, this study derives an appropriate guard interval (GI) length to be 20 ns at most for the personal desktop environment, which is compared with those in the internationally standardized 60 GHz WPAN communication systems. These two comparisons with 60 GHz bands provide evidence for the feasibility of 105 GHz wideband WPAN communication systems, which can be designed analogously from 60 GHz WPAN communication systems.
