Hello Leo, with the USRP source you can get as much bandwidth at once as your sampling rate allows, and it will give you the complex samples. The USRP source will give you all the instantaneous bandwidth the USRP delivers to your PC. You won't see more at once when using usrp_spectrum_sense, as it internally uses the very same USRP source.
I don't know which USRP model you are currently using, but all but the USRP1/b100/e1x0 will do enough bandwidth to allow you to monitor a WiFi channel at once, as long as your PC is fast enough.
