> In the Kismet log, there is a column labeled "BestSignal." Is this a measurement of the received signal strength in dbm? I am using the Intel 3945ABG wireless adapter. I presume since this value is negative, this is a dbm reading and not an RSSI value, but I am not certain. The range of values is from -93 to -13.

It's whatever the card reports.

If it's negative, yeah, it's probably dbm. I've seen cards report negative "RSSI" too, however.

-13 is pretty much totally invalid, so you've got another case of "your drivers suck, signal strength is worthless." Maybe a newer version of the drivers will report saner values.
