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 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 <adr...@freebsd.org>: > ok, I've found a few pieces about this.
