  1. 16. An evaluation of LoRa transmission parameter selection for indoor positioning

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Adina Valjakka; Anton Ahlinder; [2022]
    Nyckelord :Accuracy; Indoor positioning; LoRa; NLOS; Precision; RSSI; Transmission parameters; Trilateration;

    Sammanfattning : The purpose of this thesis is to investigate how the LoRa modulation configuration affects precision and accuracy when using LoRa for indoor positioning in non-line-of-sight conditions. The aim is to research if an optimum combination of spreading factor, bandwidth, and code rate factor can be found to result in the best possible positioning accuracy and precision, under certain predefined conditions.

  3. 17. Trådlös sensornod för mätningar av växthusgaser

    M1-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Johnny Yelda; Lucas Eriksson; [2022]
    Nyckelord :LoRa; TTN; MKR1310; Gateway;

    Sammanfattning : Greenhouse gas emissions are the biggest challenge that humans are facing because of how they can affect the global warming and the negative impact on earth. To be able to control Greenhouse gas emissions or even to minimize them we first need to be able to monitor them and then find solutions to minimize them. LÄS MER

  4. 18. Trådlös kostnadseffektiv sensornod för urbana temperatur- och luftfuktighetsmätningar

    Kandidat-uppsats, Linköpings universitet/Institutionen för systemteknik

    Nyckelord :;

    Sammanfattning : Wireless communication is becoming more common today. In all industries, there is a great interest in shifting from wired communication to wireless communication. Thus, technologies that enable wireless data transmission are becoming more suitable in the industry. LÄS MER

  7. 20. An evaluation of coverage models for LoRa

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Felix Paulsson; Issa Bitar; [2021]
    Nyckelord :LoRa; LoRaWAN; IoT; Empirical models; Path loss; Attenuation; Coverage;

    Sammanfattning : LoRaWAN is a wireless network technology based on the LoRa modulation technology. When planning such a network, it is important to estimate the network’s coverage, which can be done by calculating path loss. To do this, one can utilize empirical models of radio wave propagation.
