Re: [Discuss-gnuradio] Capture and plot 802.11 frames (Stratos Keranidis)

Hello Stratos,

For capturing 802.11 frames you can take a look here:

https://www.cgran.org/wiki/SPAN80211b

Unfortunately, that is just for the 802.11b standard. On the other hand, 
there is one encoder developed for the 802.11g standard, here: 
https://www.cgran.org/wiki/ftw80211ofdmtx
I the last case, I was able to generate 802.11g frames with an USRP2 and 
detect them with the wifi card in my laptop. That is not what you want 
but can be a good starting point.


Also, I would suggest to take a look to Wireshark 
(http://www.wireshark.org/) if you want/need to understand all the stuff 
related with sniffing (i.e, capturing data generated by other equipment).


Hope it helps,

Mario
