How to design LoRaWAN® products for scale
summary
Deployed a LoRaWAN network in Nairobi for the American Red Cross and touched roughly a hundred projects so recommendations focus on concrete risks and fixes: pick MCU and stack vendors with stable roadmaps, expect surprises at scale (200,000 units breaks insecure defaults), avoid printed join keys and shared QR-coded keys, design factory programming and key management for updates, add cheap radios like lr1110 or Bluetooth for backups, require firmware over the air updates, and never run LNS on the gateway—use managed LNS or budget real ops time for ChirpStack.
