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