Re: [USRP-users] Can the USRP B210 do passive scanning of WIFI?
In reply to this post by Martin Braun via USRP-users
the B210 is "just" SDR frontend – it will give you the "raw"
baseband spectrum as mathematically to what's on the air at the
configured center frequency.
Having a maximum analog Bandwidth of 56 MHz, yes, you can observe
a single channel. Jumping through a lot of Wifi channels is not
going to be overly fast, the B210 practically being the USRP that
has the slowest tuning/settle time.
In any case, the conversion from "complex baseband samples at a very
high rate" to "OFDM Frames" to "WiFi Packets" to "WiFi payload and
administrative data" is a software job, and not a capability of the
Think about it this way: Your question was basically "can I use this
sound card to do speech recognition-based room surveillance" to
which the answer is "yes, assuming you're very good with audio
signal processing, speech recognition and signal classification; the
soundcard is just going to give you audio samples".
