Massive MIMO Channel Measurement and Characterization for Manufacturing Scenario

One of the main differences between 5G and previous generations of cellular networks is that 5G supports not only mobile broadband enhancement, but also unprecedented reliability and very low latencies. This is beneficial to new applications in manufacturing scenario. In order to design a feasible wireless solution for manufacturing scenario, the particular characteristics of manufacturing environments need to be considered. In this paper, the massive MIMO channel measurement in factory was conducted, and the channel propagation in the spatial and frequency domains were analyzed and compared with a general indoor scenarios. Due to more metal reflections and big machine deployment, it was found that there were a lot of dense multipath so that the delay and angular spreads are larger than the ones in office scenario. Moreover, the effect of particular channel characteristics on communication system in a manufacturing scenario, was investigated in terms of CP (Cyclic Prefix) length and MIMO rank.
