We have a few units from eubus (http://www.eubus.net, ATS0760-95). They're fairly easy to interface to (we're controlling them with a BeagleBone, but need level shifting because they are 5V devices). We don't have a whole lot of seat time with them so far, but we've validated that they work.
I've managed to wire up some of these as well (using Arduino as controller). One thing I notice is that the smallest signal quality I can see reported by the NIC (ath9k) is about -81 or -82 dBm. Technically, the attenuator should be able to go below the noise floor of around -90dbm if I understand things properly. Have you done any testing of this nature? And for what it's worth, using ath9k, 1x1 MIMO (one channel) /n, ht40 on 5ghz, I get almost 8Mbps UDP download at -80 dBm signal quality :) Thanks, Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
