Abstract

The double-directional model of the radio channel is an indispensable tool in the design and evaluation of wireless systems. However, double-directional channel sounding is increasingly more difﬁcult as the carrier frequency increases due to
the need to steer narrower antenna beams across azimuth and elevation angles both at transmit (Tx) and receive (Rx) ends, resulting in a huge time duration required for measuring a single Tx-Rx link. To tackle the problem, we utilized a measurement-based ray-launcher (MBRL) to estimate the double-directional
path data from single-directional radio channel sounding. The latter performs beam scanning only at one of Tx or Rx ends, allowing us to perform many more Tx-Rx link measurements than double-directional sounding. The MBRL maps multipaths measured from the single-directional channel sounding on a
geometry of the measurement site, allowing us to identify the reﬂection points and angular information of the multipaths that we were not able to measure. Double-directional multipath data covering 12 line-of-sight and 56 non-line-of-sight indoor links at 140 GHz band are the main result of this paper. The data
will serve for the design and evaluation of communications links, localization and sensing at 140 GHz.
