- In this paper, we investigate the millimeter-wave (mmWave) propagation characteristics of large office environments based on measurement data analysis. The measurement campaign was conducted at 28, 38 and 71 GHz with a 500 MHz measurement bandwidth, which frequency bands were chosen considering the WRC-19 mmWave 5G frequencies. In particular, we focus on an open-space type office furnished with cubicle partitions. Unlike regular classical offices, cubicle partitions and pillars are major clutter sources in this office type. Compared with the existing 3GPP model, a larger path loss exponent (PLE) was observed in our LOS measurements, while a smaller PLE was observed in our NLOS measurements. This seems due to a larger hall effect rather than a wave-guiding effect. We also investigate the shadow fading statistics and the excess loss from the free space loss. In addition, we examine the delay spread statistics from the 500-MHz bandwidth measurement data.
