Thanks. Yes, Channel State Information (CSI) is absolutely worthy if available, but I am not sure how to access it. Please update me if you find any information from the baseband guys On Mon, Jun 9, 2014 at 11:34 PM, Adrian Chadd wrote: > I think the easiest thing to do is control that at the s

I think the easiest thing to do is control that at the sending side. I think maybe the channel quality stuff may have some per-stream carrier information? I'll have to ask the baseband guys. But IIRC, it won't help you. -a On 10 June 2014 00:26, mahaveer gupta wrote: > Sorry, I meant tx-chain

Sorry, I meant tx-chain mask, With 2x2 stream, I would like to measure the channel between all tx-rx antenna pairs (4 pairs in this case). So, I need to explicitly set tx-chain mask and measure rssi values from one antenna. Then change the tx-chain mask and measure rssi values corresponding to the

I see, no problem (Could be something related to MRC combining scheme). Actually, Is there another way to pull out individual RSSI values from individual antennas. which is what I am actually interested in. One alternative I can think of is to set the rx-chain-mask to 1 and 2 to get the RSSI from

I see. Thanks for the answer. Yeah, I was able to figure that out too after some hacking. Could you please let me know how the rssi from each antenna is combined into a single rs_rssi variable inside ath_rx_status. What if only one antenna is being used? Thanks On Mon, Jun 9, 2014 at 8:38 PM, Ad

Hi! This is an old post! They're the control (primary) and extension channel RSSI for each chain. RSSI combined is some combination of all of them. The control channel is the primary 20MHz channel. Extension is the other 20MHz channel half used when operating in HT40 mode. -a On 1 April 2012

hi, ath_rx_status contains 2 variables apart from rssi. rs_rssi_ctl[], rs_rssi_ext[] . Can someone explain what are their purpose ? I read in a simulator comment that rssi is combined rssi for 11n. But I did not get the meaning ? Abhinav ___ ath9k-devel
