摘要： A method of scheduling wakeup events, method of operating a mobile transceiver, and devices configured for same are provided. In one aspect, there is provided a method of scheduling wakeup events for a mobile transceiver, comprising: obtaining a first GNSS data set comprising a plurality of GNSS coordinates, the first GNSS data set defining a route; applying a curve simplification algorithm to generate a second GNSS data set comprising a plurality of GNSS coordinates, wherein the second GNSS data set is a subset of the first GNSS data set; defining one or more alarms as wakeup events to activate the satellite receiver from a low power mode based on the plurality of GNSS coordinates of the second GNSS data, wherein the one or more wakeup events are each defined by an alarm; and applying the one or more alarms.

摘要： A method and mobile transceiver having advanced network selection are provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: determining whether a current location of the mobile transceiver corresponds to a waypoint in a pre-programmed travel itinerary, the travel itinerary being stored in a memory of the mobile transceiver and defining a plurality of waypoints along a planned route, each of the waypoints defining a location, the waypoints including an origin endpoint, a destination endpoint and intermediate locations between the origin endpoint and destination endpoint; in response to a determination that the current location corresponds to a waypoint in the travel itinerary: activating a predetermined wireless transceiver from a plurality of wireless transceivers from a low power mode in accordance with the waypoint corresponding to the current location or a wake-up event.
