Hi Julian, Thank you so much for the response. By whole WiFi band, I mean from 2.401G to 2.473G, which is complete WiFi band. Is it possible to sweep entire band by using the approach you mentioned? I thought using gnuradio-companion, we can scan only one or few channels depending on the sample rate.
Regarding Hardware: I am using USRP B210 with a sample rate of 8Msps.
