Indoor positioning My journey with indoor positioning Bas Kerkhoven
Schiphol Indoor Way Finding • Up to date map •
User’s location • Routing • Search facilities
None
How did we achieve this? • Map solution connected to
GIS (geographic information system) • Routing network • Search GIS
Indoor positioning challenges • Lot’s of concrete/metal • No/bad GPS
• Solution that is cross platform
Positioning solutions Magnetic fields And a lot more
Common factors • Fingerprint the location • Third party SDK
• System restrictions • Combined with phone sensors
What we couldn’t use: Magnetic fields • It’s always there
• Can be tracked with phone sensors • Not usable for us
So which one did we use?
First solution • Started with • Infrastructure already installed
• Almost everyone has WiFi on
WiFi • Triangulation • iOS restrictions, system information • No
signal strength Benefit: Almost everyone has their WiFi on
WiFi cons • Load distributors • Lack of signal strength
• Have to be connected to SSID
What was next? • Next is: • 2000 beacons
installed across Schiphol • Multiple weeks of fingerprinting and testing
Bluetooth • Triangulation • System gives more information Disadvantage: A
lot of people have their Bluetooth off
Bluetooth pros • Accuracy +/- 5 meters • Reusability for
vendors/airlines
Bluetooth cons • Location snapped on line • Battery drain
Live! • Working solution • Correct positioning • Routing along
location
But there is more! • Apple announced indoor positioning WWDC
2014 - Session 708 - iOS
What does Apple need? • Blueprints OR • GIS (geographic
information system)
Fingerprinting • Surveyors send to location • Blueprint/GIS used to
determine location • Physically walking around Survey App
What does Apple record? • Captures all RF-signals (mostly WiFi)
• No bluetooth • Sensors of the phone • No system restrictions
Evaluation • Asses the fingerprint • Redo areas where needed
• Distribute data
How do we retrieve the location?
Build into CoreLocation • No special API’s • No extra
SDK • No authentication required
So it’s live for everyone?
How do I get the location?
Determine it’s an indoor location
Difference indoor/outdoor • CLFloor != nil -> Indoor location •
Best possible location fix
Pros • Automatically gives best location • Low battery consumption
• Smooth updates
Cons • Only iOS • Exclusive to large veneus (for
now) • Apple has to provide fingerprinting
This was my journey :)
