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 the CSI in ath9k. Is there any way to get it by my own? Thanks a lot! Sincerely Zeyu HKUST -------------- next part -------------- An HTML attachment was scrubbed...

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 signal are reflected. Of course it is possible to use special hardware (e.g. atmel transceivers or software radios) to get phase and amplitude information, but there is a interest in using off-the-shelf communication hardware to extend its purpose. I'm currently working on this topic, utilizing off-the-shelf routers with atheros chips for presence detection. @Zeyu Wang, what are your plans with CSI? If you wish you could give me a short update by mailing me. Best wishes. 2015-08-23 21:57 GMT+02:00 Adrian Chadd <adrian@freebsd.org>: > ok, I've found a few pieces about this.

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 with. I think AR9380 and later support what you saw in that paper - where you request that you get CSI data as part of some receive frame. I /think/ it's part of the TxBF support.

So is this per-frame information if the internal registers are read out right after receiving a frame, or is it always an aggregate over several received frames? > I think AR9380 and later support what you saw in that paper - where > you request that you get CSI data as part of some receive frame. I > /think/ it's part of the TxBF support. I'll have to double-check if > that's okay to extract and publish. I'm not the OP so I'm not quite sure what the paper is about. Nevertheless, I plan to use AR9590 and/or AR9390 cards so I guess that these meet the criterion of "AR9380 and later". Best Till. ^ permalink raw reply [flat|nested] 16+ messages in thread
