Positioning
The device position can be determined in 4 different ways. GPS (and Glonass), Wi-Fi, LBS
and via Beacon.
Every 3 minutes the device will determine its position, except for when it is stationary as
in below cases:
• Static. Definition of static is 7 minutes without movement. Movement is determined
by the accelerometer in the device.
• In contact with at least one beacon.
Satellite’s positioning has the highest priority. Accuracy is often about 10-100m.
Wi-Fi position is determined by 2 or more mac addresses obtained from surrounding Wi-
Fi networks. Accuracy is often about 10-100m.
Base station position is determined by data from 2 or more GSM base stations that the
device have in range. Accuracy is often less than 1000m.
Beacon. If there is a beacon registered as “home” is within range, the system know that
the user is at home.
