title: Indoor Location Positioning using 3 Wi-Fi Access Points
body: <p>I wanted to ask, is it possible to locate user's position in a building using 3 Wi-Fi Access Points?</p>
  
  <p>According to my research, it is possible, but with those 3 Wi-Fi AP, I also need to use RSSI to make it work. my question, how do I merge, or implement these 2 features as one?</p>
