What polarization should I use? brick is tough... if i were you I'd put the access points in the hallways every other floor > 3. Is one 120deg sector enough to cover a building that is about 80feet away > from building that is 64'deep, 72'high, and 170'wide (and needs to be covered > corner to corner)? just do the trig.. it's pretty easy tan 60deg *80 ~= 150 (that's from memory so check it) so you cover a horizontal area of about 300 feet at that distance. sounds like you'd be better off with a 90 degree antenna in that setup - also the 12 feet high means you'll be putting a fair amount of radiation into the ground - i think inside is a much better bet. remember that it's not important how much power your transmitter has if the clients only have 30mw - gotta talk in both directions. good luck! brad _______________________________________________ BAWUG's general wireless chat mailing list [unsubscribe] http://lists.bawug.org/mailman/listinfo/wireless
