Hi, What I've learned so far from this thread is that rs_rssi (struct ath_rx_status) is actually an SNR (not an RSSI), in dB. What's not yet clear to me is how is this value obtained. My guess from Alex's explanation is that it is the result of subtracting the gain of the AGC during a short period of silence, from gain locked on packet's preamble ... ?????
If SNR is computed during packet's preamble (which I presume should be identical regardless of the modulation used for data), why for a given tx power, I got a lower SNR when I use faster modulations? The difference between MCS0 and MCS7 is about 6dB (same for MCS8 and MCS15). Please, someone shed light... Thanks! _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
