Re: [ath9k-devel] How to get CSI from Atheros Chipset

Hi Ardian, I'm a student at Karlsruhe Institute of Technology in Germany. Recently e.g. Wang et al. showed that it is possible achive pretty good device-free human activity recognition with fine grained wifi information. The phase information is an additional magnitude in which changes in the

Re: [ath9k-devel] How to get CSI from Atheros Chipset

ok, So the legacy bits include |I| and |Q| but it's not per-frame, it's set-once-and-get-next-frame. You then read bins from the NIC itself in some shared memory inside said NIC. I'll go see if this works on the earlier chips and try to get this published, at least so there's something to start

Re: [ath9k-devel] How to get CSI from Atheros Chipset

Hi Vincent, Yes, i looked at this, but i am looking for more details on Hw register programming, and also getting the time stamping information. More over am looking for this kind of support for latest atheros 11ac chips on Ath10k driver. Cheers, -Hema On Mon, Aug 24, 2015 at 3:21 PM,

Re: [ath9k-devel] How to get CSI from Atheros Chipset

Hi Adrian, We are looking for Physical layer CSI (channel state information) extraction from ath9k/ath10k driver on latest Atheros WiFi chipsets. since we know that Hw has the readable support of estimated channel FFT buffer for a given packet. Hope this is clear to you Cheers -Hema On

Dear all, I'm a newer PhD student in HKUST and I read a paper which use the CSI information to do the localization. In the paper, the authors use the AR9390 chipset and modify the ath9k driver to get the CSI information. Recently I searched on Google and found there are some emails talked about
