If you use the USRP hardware (or any other SDR

Why do you think that USRP can't support GPRS/EDGE? Is it because of
USB latency?
no, that's not the point. The point is that you need to implement the CCU
and PCU, both of which are not present in OpenBTS.
So whether or not you combine OpenBTS with OpenBSC or run OpenBSC stand-alone,
it will always have the same features regarding GPRS (or not).
And definitely there are SDR hardware which support
GPRS/EDGE - it's
just more advanced and more integrated then USRP.
Multi-ARFCN: This is an aspect of the
radio-modem. So again, on the same
hardware any OpenBTS/OpenBSC integration will not change this.
Technically, USRP can support multi-ARFCN, but open-source version of
OpenBTS doesn't.
yes. But whether or not you combine OpenBTS with OpenBSC or run OpenBSC
stand-alone, it will always have the same features regarding multi-arfcn
