I am trying to store WiFi signals samples in a file using file sink block, using GNU radio, for spectrum sensing. I know that a single WiFi channel has a bandwidth of 20-22 MHz. So should I use the sample rate in GNU radio block to 40e6 - 44e6 or can I use a lower value? Can I use 1e6 as sampling rate?
What is the lower bound for the sample rate in GNU block?
I am confused about giving the sample rate.
