There are people and groups that are pros at doing this kind of work. Check the or youtube for it. Michel Ossman has given many great talks on how to approach and accomplish the task.

Some time ago I did try the gr-80211 but with no success, I think I got something wrong, since I had to adapt the GRC from UHD to Hackrf. Yes, a cell phone would be easier, but sometimes you need to id something that looks like wifi, behaves like wifi, but is on a weird frequency, like 3Ghz, be it a harmonic of a poorly filtered AP or a AP on a weird frequency, since there are modules and APs for uncommon frequencies that use 802.11. So I am also interested in this and would like to hear of someone that made it work. 2016-06-04 16:04 GMT+02:00 Silverfox <[email protected]>: Seeing the signals is somewhat less challenging then decoding them. The GNU Radio FFT program will display the spectrum but you would be limited by bandwidth. I don’t know if you could show the bands simultaneously. Just my opinion. I haven’t tried it. Also, you are limited by the attributes of the antenna, its height and the environment. Ubiquity makes cheap products that will do what you want for a lot less than most SDRs.

Does somebody have an idea how to do that with hack-rf? maybe there are projects out there? thanks marcus ********************** <send via mobile> Marcus Prem Dipl.- Inf.

Another problem is that most Wifi protocols require more than 20MHz of bandwidth (ref: https://en.wikipedia.org/wiki/IEEE_802.11#Protocol ) so that would be a road block.

I’d at a minimum like to get the SSIDs of all the networks in range, preferably other stats with it (security settings, signal strength, etc). I’d prefer to do this directly with Python, rather than a GUI interface. Thanks and cheers!
