It is depending on what the RSSI acronym means. :) I'd accustomed that it means
Receive Signal Strength Indicator. The madwifi (if I don't miss) never gives an
absolute RSSI so havn't such problems. Contrary in ath9k RSSI is absolute
power of signal on receiver antenna input which by definition can not depend
on noise floor. But due to noise floor measurement method used in baseband it
does.
