A field technician is preparing a mobile tablet for a delivery driver who will rely on the device for route navigation and real-time package tracking. The driver must continue to receive accurate position information even when cellular coverage is weak or unavailable. Which feature should the technician make sure is enabled on the tablet?
GPS (Global Positioning System) relies on signals received directly from satellites and therefore continues to provide location data without any cellular or Wi-Fi connectivity. Disabling all location services would block the GPS receiver, preventing the tablet from determining its position. Enabling Wi-Fi alone cannot ensure reliable positioning in areas with no nearby access points, and putting the device in airplane mode turns off the cellular radio (and often Wi-Fi), which would make map downloads or live tracking impossible-though the passive GPS receiver usually remains active, it would still lack up-to-date map data.
