USRP2 capabilities query

GNU Radio

Hi,

We are evaluating SDR platforms for conducting wireless physical layer
experiments. It would be great if some one could help with the following
information.

  1. I know that a modified version of 802.11 has been implemented and
    tested successfully on USRP1. Has it been tested on USRP2 ? Are the
    latencies in USRP2 significantly better than USRP1 to make 802.11
    feasible?

  2. Is standalone mode of USRP2 operation supported officially? Would
    USRP2 working stand-alone provide lesser latencies than a USRP2
    connected to a host computer?

Any pointers would be helpful.

Thanks,
