This article presents comprehensive double-directional channel measurements with time-domain channel sounding at 300 GHz that characterize the channel of wireless links in a data center. The channels are classified into three scenario-dependent use cases and are individually analyzed providing channel parameters as a function of the required signal-to-noise ratio of the prospective communication system. The spatial and temporal analysis of the channel reveals relevant propagation effects such as the influence of scattering and derives relations between the channel parameters of the propagation and the radio channel. The analysis shows that multipath propagation becomes relevant for systems with high signal-to-noise ratio requirements despite high-gain directional antennas. A first order approximation of relevant propagation effects complements the analysis. The measurement data of the whole measurement campaign with 18250 calibrated impulse responses including all meta data is published so that the research community has a collective benefit.
