title: Finding out distance between router and receiver?
body: <p>A general question: is it possible to retrieve information about how far away e.g. a computer is from a wifi-router. For instance I want to get data on my computer if I'm 10 meters away from my home-wifispot or 2 meters.</p>
  
  <p>Any idea if that is even possible?</p>
  
  <p>Edit: How about bluetooth? Is it possible to get information about how far away bluetooth-connected devices are one from another?</p>
