1. None

2. Indoor positioning My journey with indoor positioning Bas Kerkhoven

3. Schiphol Indoor Way Finding • Up to date map •

   User’s location • Routing • Search facilities
4. None

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

7. Positioning solutions Magnetic fields And a lot more

8. Common factors • Fingerprint the location • Third party SDK

   • System restrictions • Combined with phone sensors

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

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

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)

21. Fingerprinting • Surveyors send to location • Blueprint/GIS used to

    determine location • Physically walking around Survey App

22. What does Apple record? • Captures all RF-signals (mostly WiFi)

    • No bluetooth • Sensors of the phone • No system restrictions

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

26. So it’s live for everyone?

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

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

    • Smooth updates

31. Cons • Only iOS • Exclusive to large veneus (for

    now) • Apple has to provide fingerprinting

32. This was my journey :)
