A field technician is setting up a mobile tablet for a delivery driver. The tablet will be used for turn-by-turn navigation and real-time package tracking. The driver often travels through rural areas with little or no cellular coverage. Which of the following features should the technician verify is enabled on the tablet to obtain accurate location data under those conditions?
The mobile device's GPS receiver determines its position by reading signals from multiple satellites, so it can still calculate latitude and longitude when cellular and Wi-Fi networks are unavailable. Disabling location services would block GPS entirely. Enabling Wi-Fi alone relies on nearby access-point databases, which may not exist in sparsely populated areas. Airplane mode shuts off cellular and Wi-Fi radios and may prevent map downloads or Assisted-GPS data, making it an unsuitable choice for continuous navigation.
