   Ok, yes, we know that a device moved. We know that it could be a   
   household, or it could be a car with a wifi hot spot. More data would be   
   needed to make certain it is a household, like for example, the SSID was   
   static for years, then moved. Still, it can be that the AP was recycled.   
      
   There is no certainty, but a possibility.
