On the Real Capacity of LoRa Networks: The Impact of Non-Destructive Communications

摘要: LoRa technology has recently gained popularity, becoming one of the most promising low power wide area technologies for Internet Things due to its proprietary modulation scheme, use unlicensed sub-GHz frequency bands, and a non-destructive communication property, enabling that reception packet is not interfered by transmission with weaker signal. Based on an exhaustive evaluation setup, this work characterizes capture effect in event two or more concurrent transmissions. These results are afterwards used evaluate real performance large scale Low Power Wide Area Networks (LPWANs) based LoRaWAN protocol, showing network capacity does follow traditional pure Aloha performance, widely literature.
