  1. 1. An evaluation of coverage models for LoRa

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

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

    Abstract : 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.
