Analysis and assessment of LoRaWAN

Low-Power Wide Area Network (LPWAN) supports long-range communication for hundreds to millions smart devices and enables new types of services in Internet of Things (IoT) context. Several wireless technologies have proposed; LoRa wireless technology is arguable the most adopted, and LoRaWAN is an open standard network stack based on LoRa modulation at the physical layer. That combination promises popular connectivity in outdoor applications, while maintaining simple network structures and managements. This work provides an in-depth analysis and assessment of LoRaWAN functional components: its capabilities (total traffic load, packet delivery quality) versus its efficiency (collision and frequency usage). The evaluation based on extensive simulation study has given the hints for scalability of network deployment as well.
