Low-Power Wide Area Networking (LPWAN) technology offers long-range communication, which enables new types of services. Several solutions exist; LoRaWAN is arguable the most adopted. It promises ubiquitous connectivity in outdoor IoT applications, while keeping network structures, and management, simple. This technology has received a lot of attention in recent months from network operators and solution providers. Yet, the technology has limitations that need to be clearly understood to avoid inflated expectations and disillusionment. This article provides an impartial and fair overview of what the capabilities and the limitations of LoRaWAN are. We discuss those in the context of use cases, and list open research and development questions.
