How does a location determination work?

GPS

⟩ Accuracy up to 5m

⟩ Increases over time

⟩ Accelerated by Triangulation (A-GPS)

⟩ High power consumption

⟩ Only outdoor

Cellular Network Triangulation

⟩ Accuracy ≈ 1000m (roughly)

⟩ Reliability: Good reception

⟩ Low power consumption

⟩ Works indoor

Comparing relative signal strength from multiple antenna towers

Wi-fi Triangulation

⟩ Accuracy ≈ 60m (roughly)

⟩ Reliability: only in urban areas

⟩ Low power consumption

⟩ Works indoor

Crowd-sourced Wi-Fi location databases

Issue with Wi-fi Triangulation

⟩ Aps/Wifis can move

⟩ Leads to wrong location updates (error > 10km)

⟩ Common conference issue: Was the Web Summit really in Barcelona???

Wi-fi Triangulation on Android

⟩ Availability can be checked

⟩ Activation can be invoked

⟩ Wi-Fi scan-only mode since 4.3

Wi-fi Triangulation on iOS

⟩ Availability cannot be checked

⟩ Wi-Fi disabled à Bad accuracy

iOS App Switcher

⟩ Disables location in iOS 7.0

⟩ Location keeps enabled now (iOS 7.1 and

above)

⟩ Disables Background-Fetch

How to ensure good accuracy?

Make sure the user turns on…

⟩ Location Services (in background)

⟩ Cellular Network

⟩ GPS / “High accuracy” Location mode

⟩ …

Track Relevant User Settings

What is accuracy?

“We define accuracy as the radius of 68% confidence. In other words, if you draw a circle centered at this location's latitude and longitude, and with a radius equal to the accuracy, then there is a 68% probability that the true location is inside the circle.”

Geofencing

⟩ Auto-notifications when reaching/leaving predefined locations

⟩ 97% of Familonet user use family places feature

⟩ Number 1 reason for users to download FAMILO

FAMILY PLACES / AUTO CHECK-IN

Our Experience with native Geofencing

”The app is not working. I was checked in at home 1km away”

- Tester of an early test version of FAMILO

Our Experience with native Geofencing⟩ Urban Areas: Reliable with radius ≥ 250m

⟩ Out of town: Not reliable at all

⟩ Moderate power consumption

⟩ Non-consistent events (multiple enter events in a row)

FAMILO’s GEOFENCING TECHNOLOGY

⟩ Smartly combines GPS, Wifi- and Celltower-Triangulation

⟩ Utilization of movement patterns and stochastic models

⟩ Improved location precision

⟩ Reduction of battery consumption

⟩ Unlimited amount of places

Testing

GEOFENCING TEST SETUP

⟩ Real-world test courses

⟩ Circular fences with different radii

⟩ More than 20 test devices (iOS and Android)

⟩ More than 200 test runs over the past 3 years

Small Test Course

Sophisticated Test Course

We track the exact time of entering and leaving each geo-fence and compare it with the event time according to the Geofencing technology

Reliability by Fence RadiusAn event is counted as successful if it is fired within the given fence with a maximum delay of 6 minutes

Precision / DelayWe measure the delay between actual entrance and the Geofenceevent. Precision is defined as the median absolute value of delays.
