Re: [ath9k-devel] 4.9GHz and 5.8GHz regulatory entries?

Re: [ath9k-devel] 4.9GHz and 5.8GHz regulatory entries?
Do nothing know about FCC. As I know ist open in us without tech. Regulations like dfs or tpc. (No disturbance of radar devices in this area) In Europe (like Austria) the channel 149-165 are used for comm. services acc the srd-specification but are NOT ism and has to be coordinated by the local frequency office.

[ath9k-devel] Cross-Modulation distortion on UBNT devices
Hi Adrian We are using NanoStantion and ArirGrids with last OpenWRT trunk and ath9k also in cowded situations and with heavy signals on neighbour channels. Do you have any info about the maximum input signal which can be handled without bit-errors and if the preamp is part of a working AGC.

Re: [ath9k-devel] Disabling Rate control in ath9k
Hi, only for understanding guys. Does (echo -1 > /sys/kernel/debug/ieee80211/phy0/rc/fixed_rate_idx) disable fixed rate functionality?

Re: [ath9k-devel] External LNA gain.
Hi Adrian, 2011/12/8 Adrian Chadd > Ask me after wednesday. Ill be working at atheros. :) > > Adrian > > Still cool @ atheros :-) Hope u get the infos for the LNA-gain bug out of the company. We noticed in Vienna, that near all UBNT Products should have the problem. A comparison between Bullet M, NanoStation, NanoBridge ans AirGrids shows, that only Bullet M has the expected sensitivity. Guess it has 2do with the LNAs. Good luck Joe ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
