Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org Dear developers, Is there a way to get a gain value of AGC? To get nearly-correct RSSI, or CSI magnitude values, I think I need to know how much gain is obtained from AGC. Intel 5300 NIC (iwlwifi) can get a such AGC value with this tool. ( http://dhalperi.github.io/linux-80211n-csitool/) However, its Atheros version (http://pdcc.ntu.edu.sg/wands/Atheros/), doesn't have a such functionality. I wonder whether the author did not implement it, or it can't be implemented in aht9k. Some quick search gives me this link ( https://www.mail-archive.com/search?l=ath9k-devel at lists.ath9k.org&q=subject:%22%5C%5Bath9k%5C-devel%5C%5D+More+on+signal+and+noise%22&o=newest&f=1 ). It says that it is impossible because AGC is implemented with CMOS technology. Since it's a quite old thread and time passed, I'd like to check if there is any updates to get AGC, or correct RSSI, CSI magnitude.
