“…Therefore, a precise RT model was obtained from point cloud data from extensive 3D laser scans in an arbitrary industrial scenario, in which multiband RF measurements were also conducted simultaneously for propagation characterization [29] and calibration and verification of the model at sub-6 GHz and mmWave [30]. In addition, simultaneous sub-6 GHz, mmWave, sub-THz, and OWC measurements will be conducted for verification purposes in the future.…”
