Right. Hence, interference and channel busy. The Atheros NIC channel busy tells you % busy with signal in the air _AND_ % busy receiving frames. So you can get an idea of what's actually going on. The basics are in the Atheros HAL. We just need a nice way to wrap it up and hand off channel survey results to the net80211 layer so it can make these decisions. -adrian _______________________________________________ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org"
