   Looking at the user guide, they do give a noise figure, which is 5dB.   
   That is pretty poor!  You can get UHF pre-amplifiers with 0.5dB noise   
   figures.   
      
   There is no mention of a pairing process, so I assume that it is a   
   simple repeater.   
      
   They do say that the power will be reduced if the device detects too   
   much signal between inside and outside.   
      
   Nothing I can see in the FCC Test Report   
    suggests any bluetooth capability   
   or ability to honour power control signalling.
