LoRaWAN and Agritech: Success, failures, lessons learned, future
summary
Choice of radio matters: using RN2483 and RN2903 modules sped development in 2018 but forced firmware workarounds and limited control so a smaller modern chip would be chosen now; LoRaWAN gives low power, cheaper BOM and remote reconfiguration via The Things Network yet connectivity breaks cause packet loss and maintenance is painful when gateways are remote; payload limits bite if many sensors so the default 15 minute transfer interval and careful payload design are chosen; good range needs line of sight and some deployments reach 60 km line of sight
