A Comprehensive Assessment of LoRaWAN and NB-IoT Performance Metrics Under Varied Payload Data Sizes

Internet of Things (IoT) has revolutionized whole industries, simply because it has provided constant connectivity between devices that hitherto existed in isolation. This made Low Power Wide Area Networks (LPWAN) the network of choice when it comes to implementing IoT, because they guarantee long-range communication and low power consumption. The research and industry communities put a strong emphasis on LoRaWAN and NB-IoT among the LPWAN technologies. This paper presents a comprehensive assessment of the performance metrics of LoRaWAN and NBIoT under varied payload data sizes. The findings are substantially notable in two methods: LoRaWAN and NB-IoT. In comparing NB-IoT with LoRaWAN, it is evident that it has an overall trend to more problems in the transmission with an increase in the size of the payload. Albeit with higher bit error rates than LoRaWAN, NB-IoT generally is more susceptible to the risk of suffering from communication-related issues. This implies that LoRaWAN will always be in a position to achieve faster speeds of connectivity as compared to NB-IoT because its transmission time is smaller. LoRaWAN is always good for the whole time in terms of energy efficiency compared to NBIoT; it uses less energy with different sizes of payload. Furthermore, LoRaWAN provides constant resource use, whereas with NB-IoT, a lesser amount of resource is used to transmit the same amount of data.
