Prototip sledilne naprave v omrežjih LTE-M in NB-IoT

BRATEC, KLEMEN (author), Bulić, Patricio (mentor)

Diplomska naloga predstavi razvoj sledilne naprave ter spremljajoče zaledne in spletne aplikacije. Naprava za pridobivanje lokacije uporablja sistem GPS, za povezovanje v internet pa mobilni omrežji LTE-M in NB-IoT. V prvem delu naloga pregleda in primerja širše uporabljena omrežja LPWAN, preveri primernost izbora tehnologij LTE-M in NB-IoT, predstavi protokole za komunikacijo ter pregleda področje pridobivanja lokacije naprav. V drugem delu pa predstavi razvoj sledilne naprave. Najprej opiše sistem v paketu Nordic nRF9160, ki predstavlja osnovni gradnik na ravni strojne opreme, njegovo razvojno okolje in operacijski sistem, nato pa predstavi delovanje zaledne in spletne aplikacije ter način komunikacije med sledilno napravo in zaledno aplikacijo.

Abstract

This bachelor thesis presents the development of a tracking device based on GPS positioning and LTE-M and NB-IoT cellular connectivity. It begins with an overview of different types of LPWAN networks, explores the characteristics of LTE-M and NB-IoT, presents common communication protocols for IoT devices communicating over the Internet and describes some of the widely used IoT positioning methods. In the second part it focuses on the development of the tracking device where it first presents the system-in-package Nordic nRF9160 and proceeds with an overview of the software development kit, OS and IDE used for the development of the embedded software. In the end it presents the backend application along with the web app for viewing the location of different tracking devices.
