  1. 1. LoRa Radio Performance Analysis Based on AVR-RSS2 and RIOT-OS for Indoor IoT Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : HongShuo Yi; Duosi Dai; [2023]
    Keywords : LoRa; Indoor IoT Internet of Things ; Signal strength; Round-trip time RTT ; Goodput; LoRaWAN device classes; AVR-RSS2; RIOT-OS; LoRa; Inomhus-IoT Internet of Things ; Signalstyrka; Rundresa-tid RTT ; Goodput; LoRaWAN klasser; AVR-RSS2; RIOT-OS;

    Abstract : This thesis is dedicated to measuring the communication performance of LoRa technology in an indoor environment and providing insight into its potential application as an effective Internet of Things (IoT) communication solution in Low Power Wide Area Networks (LPWAN). Through careful experimentation and analysis, we assessed various transmission parameters such as spreading factor (SF), bandwidth (BW), Payload Length (PL), and LoRaWAN classes. READ MORE
