You mean the USRP ? As far as I know its no big problem to save the
raw RF data with it but there is no easy-to-use software yet to get
nice traces from those data (e.g. extract all the different channels
like BCCH, CCCH and so on) which for example could be used to see the
messages between the BTS and the phone. I am not interested in the
traffic (speech or data), just the signaling on the Air-Interface would
be nice to have. But lets see what the future brings, projects like might fill this gap.
