Broadband channel propagation measurements on millimeter and sub-millimeter waves in a desktop download scenario

Along with the steady increase of data rates in communication applications, the utilized bandwidths are growing accordingly, thus requiring higher carrier frequencies in face of the almost entirely occupied spectrum in the mm wave range and below. Therefore, channel measurements up to the lower THz frequency range are necessary for the development of modern and future communication systems. In this paper we present a comprehensive channel characterization covering the complete five waveguide frequency bands from 50 GHz up to 325 GHz. The measurements are performed in conditions which simulate a short-range indoor download environment. For spatially resolved measurements, a motorized setup was designed and employed.
