Dear Dave,
So this channel concept lies in GNU Radio.
No. The concept "channel" is how you, as a signal processing expert,
look at a piece of spectrum. GNU Radio just sees samples.
If you build a GNU Radio system that filters out specific parts of
the spectrum that *you* consider to be the channels of interest,
then you'd have something that understands channels. Again, the
implementation of the idea "this part of spectrum is a channel" is
completely up to you -- all the hard- and software involved just
sees a sequence of digital numbers.
Best regards,
Marcus

Thanks for the reply Marcus. So this channel concept
lies in GNU Radio. How can I really set from what channel I need
to send the data or which channels are free for the
transmission. Do I need to write any code for that? I am
performing DARPA Spectrum competition wherein I need to perform
data transmission between two USRP by sensing which channels are
free and sending the data. Please suggest
Thank you

Dave,
the USRP has no notion of "channels". It's a concept that
you have in your software that deals with the samples coming
from the USRP.
You can configure the USRP to arbitrary center frequencies.

I would like to send data through specific
channels among the USRP. How do I know what channels are
available? I have tried to search for channels but I was
not successful. Are there any commands that I need to
provide for the available channels? Kindly help.
Thank you

Hey all,
I would like to perform a specific application
of competitive strategy(competition) with my two
USRP available by detecting which channel is
available for doing that. I have used the command
of ./usrp_spectrum_sense.py 2.434G 2.438G which
have shown me the results which is attached in
the picture below. I would like to know of how to
select which channel or frequency band is
available for performing my competition and how
will I be able to perform? Any suggestions are
kindly appreciated. Sorry if I am not too brief
with that. Thanks
