Hi,
I would like to record signal strength and noise level for each client packet received on a wireless access point. I found the fields IEEE80211_RADIOTAP_DBM_ANTSIGNAL and IEEE80211_RADIOTAP_DBM_ANTNOISE in the radiotap header which should give me this information. The 'wi' interface sets both of these values in if_wi.c if_wi.c: sc->sc_rx_th.wr_antnoise = frmhdr.wi_rx_silence; if_wi.c: sc->sc_rx_th.wr_antsignal = frmhdr.wi_rx_signal; While the 'ath' interface only provides signal strength information. if_ath.c sc->sc_rx_th.wr_antsignal = ds->ds_rxstat.rs_rssi; Is the Atheros driver (which my current wireless card in the AP uses) capable of providing noise information? If yes, which line needs to be added in if_ath.c? Thanks, Tanja _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
