  4. 4. GPS-Tracking Device with Long Range and Bluetooth Low Energy Communication

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Rasmus Oliv; [2019]
    Keywords : GPS; LoRa; BLE;

    Abstract : The thesis is about the construction of a GPS-tracker that can read NFC (Near Field Communication)-tags and communicate with LoRa (Long Range) and BLE (Bluetooth low energy) and investigate which of the components in the GPS-tracker that consumes most power. The usage area for the GPS-tracker is to make the work on disaster affected sites more efficient and secure by having an operation leader that can organizing the operation with help of the information provided by the GPS-trackers that are placed on the injured people and recuing personnel.
