Conclusion

Implementing LPWAN connectivity technology for an IoT solution can be a complex challenge. Each of the available LPWAN technologies offers its own unique set of features, but also has limitations that should be considered. This whitepaper outlined the trade-offs between the features of LPWAN technologies. AWS customers have a wide range of viable options for implementing their LPWAN solutions with NB-IoT, LTE-M, LoRaWAN, and Sigfox.

To support architectural decisions, this whitepaper provided an overview and detailed description of the most common architectural patterns. For NB-IoT and LTE-M, implementation using UDP, CoAP, and MQTT was described. For LoRaWAN, implementation patterns for both public and private LoRaWAN networks was covered. For Sigfox, implementation recommendations for both uplink and downlink communication was described.
