Stop Using JSON: Why Binary Protocols are Mandatory for LoRaWAN Emergency Alerts

The hard 51-byte limit of LoRaWAN frames makes standard JSON alerts impractical, leading to reliability issues in critical emergency scenarios. Adopting binary formats like ECP ensures single-frame delivery, significantly reducing latency and the risk of message fragmentation failure. This shift highlights a broader trend in IoT where protocol efficiency is prioritized over human-readable data formats for mission-critical reliability.
