Abstract
A method for location-based zone triggering is disclosed. The method generally includes the step of (A) generating a position signal conveying a location of a device in at least two spatial dimensions in response to a plurality of navigation signals received from external the device and (B) generating a trigger signal at an interface based on the position signal, (i) a first aspect of the trigger signal indicating that the location is crossing a boundary of a zone, (ii) a second aspect of the trigger signal indicating that the device is one of entering the zone and leaving the zone and (iii) the interface adapting a zone module to communicate the trigger signal to an application module.
