A little bit of research reveals this:
4.10 ssi_type
The ssi_type field is used to indicate what type of signal strength
information is present: "None", "Normalized RSSI" or "dBm". "None"
indicates that the underlying WLAN device does not supply any signal
strength at all and the ssi_* values are unset. "Normalized RSSI"
values are integers in the range [0-1000] where higher numbers
indicate stronger signal. "dBm" values indicate an actual signal
strength measurement quantity and are usually in the range [-108 - 10].
The following values indicate the three types:
Value Description
---------------------------------------------
0 None
1 Normalized RSSI
2 dBm
3 Raw RSSI
Supposedly, all packets are supposed to contain this header
information, so it should be a matter of parsing it and converting it
to a standard format.
