title: Sampling Frequency for capturing the wlan signal in USRP2
body: <p>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 Receiever be operated on ?</p>
  
  <p>I was capturing the signal at 10MSps. Can I capture the whole spectrum with this sampling rate. ( Bandwidth of wlan : 22MHz).</p>
  
  <p>Is it possible to operate the USRP2 at a frequency which is a integral multiple of the the Chipping Frequency of wlan (11Mchips / sec )</p>
  
  <p>If not, what frequency do I need to operate the Receiever ?</p>
  
  <p>Thanks
