Adapter Signal Level Correction

Because TamoGraph supports a large number of different Wi-Fi adapters in various form factors, using various antennas, it is impossible to ensure that the signal level readings provided by these adapters are exactly the same. You may want to correct the signal levels reported by your adapter using the functionality described below, so that passive surveys conducted using different adapters would have a similar baseline.

IMPORTANT: This feature is intended for advanced users only. Please do not utilize it unless you have a very good understanding of what exactly you are doing. If you want to simulate clients with different adapter sensitivity levels, consider using the Client Capabilities configuration instead.

To access this functionality, either click Settings => Adapter Signal Level Correction or double-click on the adapter name in the left corner of application the status bar. The configuration dialog allows you to specify a pair of negative or positive values (one per frequency band) in dBm by which the raw signal levels reported by the adapter will be corrected. The values that you enter are saved as a preset associated with the specific adapter model. If you use different adapters, each adapter will have its own correction levels (if any are specified). Clicking Reset sets the correction levels to zero.

Once you have entered the values and clicked OK, the specified correction levels (if they are non-zero) will be shown next to the adapter name in the status bar. This allows you to see if any corrections are being applied without opening the configuration dialog.

Corrections affect all packets received during passive surveys, as well as the real-time signal levels shown in the AP list on the left panel. Corrections DO NOT affect data recorded in previously conducted surveys; they are NOT retroactive.
