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.

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 youRegards,

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.
Best regards,

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 youRegards,

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
Regards,Dave
