Hi all, Just three questions. I need per-packet SNR information and my first guess was to inspect "last_signal" from debugfs. Values range from -30 to -60. last_signal file should contain signal (dBm) of last received frame (from sta_info.h), right? That explains values obtained. But...
1) This value is computed as signal=ATH_DEFAULT_NOISE_FLOOR + rx_stats->rs_rssi, which is confusing me. It would be explained if rs_rssi is actually SNR (not RSSI) measured in dB. Am I wrong? 2) Why is NOISE_FLOOR fixed to -95 (dBm?). Noise varies randomly, e.g. noise reported by iw survey dump vary from -91 to -101 dBm. 3) By the way, what do rs_rssi_ctlX and rs_rssi_extX (-1 < X < 3) measure? Thank you! _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
