  Providing reliable low latency wireless links for advanced manufacturing and
processing systems is a vision of Industry 4.0. Developing, testing and rating
requires accurate models of the radio propagation channel. The current 3GPP-NR
model as well as the QuaDRiGa model lack the propagation parameters for the
industrial indoor scenario. To close this gap, measurements were conducted at
2.37 GHz and 5.4 GHz at operational Siemens premises in Nuremberg, Germany.
Furthermore, the campaign was planned to allow the test and parameterization of
new features of the QuaDRiGa channel model such as support for device-to-device
(D2D) radio links and spatial consistency. A total of 5.9 km measurement track
was used to extract the statistical model parameters for line of sight (LOS)
and Non-LOS propagation conditions. It was found that the metallic walls and
objects in the halls create a rich scattering environment, where a large number
of multipath components arrive at the receiver from all directions. This leads
to a robust communication link, provided that the transceivers can handle the
interference. The extracted parameters can be used in geometric-stochastic
channel models such as QuaDRiGa to support simulation studies, both on link and
system level.
