  Many concepts for future generations of wireless communication systems use
coherent processing of signals from many distributed antennas. The aim is to
improve communication reliability, capacity, and energy efficiency and provide
possibilities for new applications through integrated communication and
sensing. The large bandwidths available in the higher bands have inspired much
work regarding sensing in the mmWave and sub-THz bands; however, the sub-6 GHz
cellular bands will still be the main provider of wide cellular coverage due to
the more favorable propagation conditions. In this paper, we present a
measurement system and results of sub-6 GHz distributed MIMO measurements
performed in an industrial environment. From the measurements, we evaluated the
diversity for both large-scale and small-scale fading and characterized the
link reliability. We also analyzed the possibility of multistatic sensing and
positioning of users in the environment, with the initial results showing a
mean-square error below 20 cm on the estimated position. Further, the results
clearly showed that new channel models are needed that are spatially consistent
and deal with the nonstationary channel properties among the antennas.
