Hi Fikrat,
The sampling rate must be twice the BANDWIDTH that you want. I don't know much about
WiFi, but from the numbers you give, the range of frequencies you are interested in seems to
span about 2.447 - 2.427 GHz = 20 MHz. The receiver users an analog mixer to shift the frequency
band you want down to near zero frequency, so sample with 50 MHz should be adequate.
Sincerely,
Dan Marlow

Subject: [Discuss-gnuradio] Max Sampling Rate Limitation
Dear all,
![]()
I am trying to monitor Wi-Fi channel number 6 which ranges from 2.427GHz to 2.447GHz.
As I read though, the sampling rate must be at least double the highest frequency, which in my case is equal to 4.894GHz. However, the USRP has a limit of 50MHz that I cannot exceed (I tried and it kept giving me actual sampling rate = 50MHz). Is there
a way around it so that I can reconstruct the signal without much losses? What proper sampling rate can I choose?
Best regards,
Fikrat
