Abstract

Embodiments enable geofencing applications and beacon watch lists. A computing device with at least a first processor and a second processor identifies a set of beacons associated with a geofence. The first processor consumes less power when operating than the second processor. The first processor is provided with the identified set of beacons. In beacon watch list embodiments, the first processor detects one or more beacons proximate to the computing device, compares the detected beacons with the provided set of beacons to determine whether the computing device is within the geofence, and updates a location status based on the comparison. In tiered geofencing implementations, the computing device switches among positioning modalities based on a distance from the computing device to the geofence to save power.
