title: What is meaning of negative dbm in signal strength?
body: <p>When we try to get nearby cells and their LAC, MNC, signal (and while using other android apps) we are getting signal as negative value (like -85dbm). How should I take this? Should I ignore  -ve sign and take absolute value or -85 is smaller strength than -60?</p>
  
  <p>How this will affect my location finding?</p>
