I've built a small community wireless network One central AP with 2 radios One is for clients, the other is a backhaul link to a dedicated access point that connects to the firewall and the internet.
I'm using smc radios (prism chipset - 200mW 1.7.4firmware, hostap) and panel antennae on both sides of the backhaul link. i see signal levels between -40dBm and -60dBm (20!db?) the noise level is almost always static at -92dBm The link quality metric is extremely variable - going between 90 and ~0 dB here are the graphs http://charterstreet.dyndns.org/rrd/ Sometimes i actually lose the connection What could explain 1) the wild variation in "Link Quality" 2) the less wild but still very big variation in signal level.. obviously link quality depends on signal level but there's certainly something else in play. the noise level seems to be useless _______________________________________________ BAWUG's general wireless chat mailing list [unsubscribe] http://lists.bawug.org/mailman/listinfo/wireless
