Spatial Properties of Industrial Wireless Ultra-Reliable Low-Latency Communication MIMO Links

We show the results of a measurement campaign done in an industrial hall, and analyse a frequency-selective 2 × 2 multiple-input multiple-output channel. The transmitter is kept static while the receiver moves across a positioning board between line-of-sight and obstructed line-of-sight. We compare...

Description
Summary:We show the results of a measurement campaign done in an industrial hall, and analyse a frequency-selective 2 × 2 multiple-input multiple-output channel. The transmitter is kept static while the receiver moves across a positioning board between line-of-sight and obstructed line-of-sight. We compare capacities, delay spreads and fading patterns of different antenna settings. We observe that higher outage capacity is achieved when using co-polarized rather than cross-polarized dipoles. The settings with higher capacity rates also show lower root-mean-square delay spread values, due to the presence of a strong line-of-sight component. We observe how polarization and antenna alignment influence the fading patterns.
