well, WiFi is split into channels of bw=12, 20 or 40 MHz, depending on the standards we're looking at.
I don't think I'll tell you something new when I recommend that you
1. isolate these bw wide channels from the f_sample >= bw wide digital signal coming from the USRP,
2. estimate the power contained within these,
3. store the results
So with what of these three steps do you have problems? As generally as you ask this now, it's going to be a bit hard to help you...
If you haven't already, read the Guided Tutorials[1]. They are short, a fun (and rewarding) read, and they should give you knowledge of most methods you'll need to achieve what you need.
Best regards,

Hello everyone,
I hope you're all doing well.
I'm new to gnuRadio and I need your assistance in a project I'm working on if it's not too much to ask.
The objective of my project is to receive wi-fi signals from my surrounding using the USRP and save the power level as well as the frequencies we are sensing onto a file sink to be able to apply some machine learning algorithms on the data stored using MATLAB. ( create a predictor that can tell us when the Wi-Fi channel is going to be idle or not based on the power level we stored using the USRP ).
I attempted to take a go at it, but I'm confused as to what blocks I should use or from where to start. Can anyone advise me or give me a starting point to build on? I would be forever grateful.
Thank you all for your help!
Best regards,FiFi
