description: Channel gain of 5.8 GHz radio band within factory environment 1 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.date/time of measurement start: 2015-09-02date/time of measurement end: 2015-11-25collection environment: We measured the channel gain within a factory environment between one transmitting antenna and multiple receiving antennas.network configuration: Each antenna was mounted on tripods. 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. The trace contains a ZIP-archive of CSV measurement files, measurement setup figure and antenna view figures. The VNA performed 200 sweeps.file: channel-gain-M2-timevariant-pedestrian.zipconfiguration: The line-of-sight was obstructet (O-LOS) for the antenna separations of 3.1 m, 10.0 m and 20.4 m due to industrial machineries and tools. There was pedestrian motion during the measurements along the green path in the measurement setup figure for the time interval 4 s ... 12 s. The antennas are aligned vertically. Normalization was performed to eliminate the error due to the cables and adapters.format: The forward transmission coefficients values of 200 measurement sweeps are stored in CSV files as floats with one headline. The first column represent the frequency in Hz. The next 200 columns store the magnitude in dB and the final 200 columns angle in degree. Example: freq_Hz,mag_dBm_ 1,mag_dBm_ 2, ..., mag_dBm_200,angle_degree_ 1,angle_degree_ 2, ..., angle_degree_200 5300000000,-52.13,-52.81, ... -54.10,-86.78,-93.13, ...,-89.77 5301000000, ... ... The 200 sweeps are measured consecutively. The duration of the equidistant measurement sweeps is 85.085 ms.
