Sampling Frequency for capturing the wlan signal in USRP2

I am working on a wlan Receiver and using USRP2 for receieving the signal. I would like to know what should be the sampling rate that the Receiev开发者_Python百科er be operated on ?

I was capturing the signal at 10MSps. Can I capture the whole spectrum with this sampling rate. ( Bandwidth of wlan : 22MHz).

Is it possible to operate the USRP2 at a frequency which is a integral multiple of the the Chipping Frequency of wlan (11Mchips / sec )

If not, what frequency do I need to operate the Receiever ?

Thanks Kiran

these re specific questions for GNU Radio community or even the Ettus Research company.

There are some WiFi implementation for GR already done so you may look into the BBN802.11 project page on CGRAN, and take a look at their usrp2_version branch for more help.
