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.
