It is a method that is used in Global Positioning Systems but we intend to use the same principle in indoor localization. 44 As illustrated below, knowing an object's relative distance from Boise, Minneapolis and Tucson, one can derive that that object is in Denver. Similarly, knowing a person's location from three USRPs enables us to roughly estimate his position in an indoor place. 45 45 </tr> 46 46 <tr> 47 47 <td> 48 48 <center><b> Trilateration </b> </center> 49 </td>50 <td>51 <center><b> Triangulation </b> </center>52 49 </td> 53 50 </tr> … … 56 53 57 54 58 </center> 55 59 56 }}} 60 57
