Description of fields of each row entry within the .csv file.
| Field | Description |
|---|---|
| Seq | The order of packets captured or transmitted. |
| Timestamp | The exact time when the packets was captured or received. |
| target_seq | The sequence number associated with the activity. |
| Target | The activity performed by the volunteer. |
| Mac | The MAC address of the Tx. |
| Rssi | RSSI represents the strength of the signal captured by the Rx. |
| Rate | The speed of communication link between devices, typically measured in Mbps (Megabits per second). |
| sig_mode | The modulation and encoding scheme used for transmitting data. |
| Mcs | The Modulation and Coding Scheme (MCS) specifies the combination of modulation and error correction coding used in wireless communication. |
| Cwb | The channel bandwidth or the range of frequencies allocated for communication. |
| smoothing | This field indicates whether smoothing is applied during transmission. |
| not_sounding | This field indicates whether a sounding frame is being used for channel estimation and feedback. |
| aggregation | This field indicates whether multiple data frames are combined into a single transmission unit. |
| stbc | This field indicates whether Space-Time Block Coding (STBC) is employed to improve the reliability of wireless communication by transmitting redundant data across multiple antennas. |
| fec_coding | The type of Forward Error Correction (FEC) coding used, if any. |
| sgi | This field indicates whether Short Guard Interval (SGI) is enabled to reduce the guard interval between symbols in wireless communication. |
| noise_floor | The level of background noise in the communication channel |
| ampdu_cnt | The number of A-MPDU (Aggregate MAC Protocol Data Unit) transmitted or received. |
| channel_primary | The specific frequency band used for transmission |
| channel_secondary | The secondary channel used to increase data transmission rate, if applicable. |
| local_timestamp | The timestamp relative to the local time of the device capturing the packet. |
| ant | The antenna used for transmitting or receiving the packet. |
| sig_len | The size of the signal or frame in bytes. |
| rx_state | the operational state of the Rx. |
| len | The length of the packet in bytes. |
| first_word | The information about the first word or header of the packet. |
| data | The actual payload or content of the packet. In this context, data refers to the CSI subcarriers captured. |
