Lambda/2 dipole antennas were used.data collection methodology: The vector network analyzer (VNA) Rohde and Schwarz ZVB-8 was used to measure the forward transmission coefficients (channel gain). The forward transmission coefficients were measured simultaneously.sanitization: The measured channel gain doesn't contain any privacy-related information.change: Traces M2 and M3 added.Tracesetfactory1-channel-gainChannel gain of 5.8 GHz radio band within factory environment 1file: init-factory.tar.gzdescription: Measurement of the channel gain with the center frequency 5.8 GHz, span 1 GHz and resolution bandwidth of 1 MHz within factory environment 1.measurement purpose: Bit Error Characterization, MAC Protocol Developmentfactory1-channel-gain Tracesfactory1-channel-gain/M1: Time-invariant and frequency-variant 5.8 GHz channel gain within a factory environment. The trace contains a ZIP-archive of CSV measurement files, measurement setup figure and antenna view figures. The VNA performed a single sweep. Note that this file was named channel-gain-M1.zip in the 2015-09-18 version of this dataset.file: channel-gain-M1.zipconfiguration: The line-of-sight was obstructet (O-LOS) for the antenna separations of 3.1 m, 9.2 m and 20.5 m due to industrial machineries and tools. There was no motion during the measurements. The antennas are vertical aligned. The TOSM calibration was performed to eliminate the error due to the cables and adapters.format: The forward transmission coefficients values are stored in CSV files as floats with three headlines. The three columns represent the frequency in Hz, the magnitude in dB and the angle in degree of the transmission coefficient trace point, respectivly. So, measurement file of s_21 starts with: # Version 1.00 # freq[Hz];db:Trc1_S21;ang:Trc1_S21; 5.300000000000000E 009;-5.779730205623061E 001;8.480955521472387E 001; 5.301000000000000E 009;-6.193244959783340E 001;5.826833065447170E 001; ...factory1-channel-gain/M2: Time-variant and frequency-variant 5.8 GHz channel gain within a factory environment with pedestrian movement.
