Measurement data of the industrial IoT scenario

In these measurements considered in this dataset, 15 measurement points are deployed in the scenario. They are sorted in two groups. Among line 1, all measurement points are LoS scenarios. Among line 2, measurement points 1, 2, 3, 4, 5,and 7 are LoS scenarios, and measurement points 6, 8, 9 are NLoS scenarios. Due to the limitation of the cable length, measurement data of line 2 locations 1-6 is collected at mmwave band. The heights of the Tx antenna and the Rx antenna are 2.05 m and 1.45 m, respectively.  The bandwidth of the intermediate frequency filter of the adopted VNA is 2 kHz. Both the Tx and the Rx antennas are omnidirectional antennas. 200 snapshots are collect at each Rx location. In terms of the 3-4 GHz  data, the bandwidth is 1 GHz. The number of frequency points swept in each snapshot is 501. In the aspect of 38-39 GHz and 39-40 GHz data, the center frequencies are 38.5 GHz and 39.5 GHz with 1 GHz bandwidth, respectively. The number of frequency points swept in each snapshot is also 501.

Methods
This dataset is collected in a large-scale textile factory, a typical representative of most of the textile production workshops of exact enterprises. The channel measurement equipment applied in the measurements consists of a programmable vector network analyzer and necessary auxiliaries. An extensive amount of data in line-of-sight (LoS) and non-line-of-sight (NLoS) scenarios is collected with omnidirectional antennas in both transmitter and receiver ends. This dataset contains raw data and calibration data.
