3. Schiphol
   Indoor Way Finding
   • Up to date map
   • User’s location
   • Routing
   • Search facilities

5. How did we achieve this?
   • Map solution connected to GIS (geographic information system)
   • Routing network
   • Search GIS

6. Indoor positioning challenges
   • Lot’s of concrete/metal
   • No/bad GPS
   • Solution that is cross platform
   

   View Slide

7. Positioning solutions
   Magnetic fields
   And a lot more
   

   View Slide

8. Common factors
   • Fingerprint the location
   • Third party SDK
   • System restrictions
   • Combined with phone sensors
   

   View Slide

9. What we couldn’t use:
   Magnetic fields
   • It’s always there
   • Can be tracked with phone sensors
   • Not usable for us

10. So which one did we use?

11. First solution
    • Started with 

    • Infrastructure already installed

    • Almost everyone has WiFi on
    

    View Slide

12. WiFi
    • Triangulation
    • iOS restrictions, system information
    • No signal strength

    

    Benefit:

    Almost everyone has

    their WiFi on

13. WiFi cons
    • Load distributors

    • Lack of signal strength

    • Have to be connected to SSID

14. What was next?
    • Next is: 

    • 2000 beacons installed across Schiphol

    • Multiple weeks of fingerprinting and testing

15. Bluetooth
    • Triangulation
    • System gives more information

    Disadvantage:

    A lot of people have

    their Bluetooth off

16. Bluetooth pros
    • Accuracy +/- 5 meters

    • Reusability for vendors/airlines
    

    View Slide

17. Bluetooth cons
    • Location snapped on line

    • Battery drain

18. Live!
    • Working solution

    • Correct positioning
    • Routing along location

19. But there is more!
    • Apple announced indoor positioning

    WWDC 2014 - Session 708 - iOS

20. What does Apple need?
    • Blueprints
    OR
    • GIS

    (geographic information system)
    

    View Slide

21. Fingerprinting
    • Surveyors send to location
    • Blueprint/GIS used to determine location
    • Physically walking around
    Survey App
    

    View Slide

22. What does Apple record?
    • Captures all RF-signals (mostly WiFi)
    • No bluetooth
    • Sensors of the phone
    • No system restrictions
    

    View Slide

23. Evaluation
    • Asses the fingerprint
    • Redo areas where needed
    • Distribute data

24. How do we retrieve the location?

25. Build into CoreLocation
    • No special API’s
    • No extra SDK
    • No authentication required

27. How do I get the location?

28. Determine it’s an indoor location

29. Difference indoor/outdoor
    • CLFloor != nil -> Indoor location
    • Best possible location fix
    

    View Slide

30. Pros
    • Automatically gives best location
    • Low battery consumption
    • Smooth updates
    

    View Slide

31. Cons
    • Only iOS
    • Exclusive to large veneus (for now)
    • Apple has to provide fingerprinting
