The upcoming 3GPP global mobile communication standard 6G strives to push the technological limits of radio frequency (RF) communication even further than its predecessors: Sum data rates beyond 100Gbit/s, RF bandwidths above 1GHz per link, and sub-m

Radio access at mm-waves has been subject of intensive research in the latest years. However, within the initial deployment of 5G, mm-waves are still relegated and there is a generalized idea that the mm-wave channel for radio access, in comparison t

The polarization behavior of the mobile MIMO radio channel is analyzed from polarimetric double-directional channel measurements, which were performed in a macrocell rural environment in Tokyo. The recorded data comprise non-line-of-sight, obstructed

The potential of broadband THz communication system is not limited to extremely high data rate transmissions up to several TBit/s. Rather, the true application potential of THz systems will be created by the combination of the communication and radar

The bottleneck in OTA testing electrically large equipment is the large number of sources required for sufficient angular density. That is, if the sources are active. In that case, high-bandwidth, high-frequency equipment with excellent stability, pr

While traditional testing methods as conducted and open field tests have their limitations in terms of realism and repeatability of the scenario’s conditions, Over-the-Air (OTA) testing enhances the way that GNSS and mobile communications systems w

In the present paper we introduce unique double-directional dual-polarized measurements at 190 GHz in a conference room with the aim of characterizing propagation for channel modelling and beam-forming applications. Assisted by ray-tracing, multiple
