Relaying and Delivery Assurance in Long-Range Radio Alerting for Remote Areas: A Review with a Preliminary Bench Observation

The literature shows that LoRa links are long and that relaying is feasible, but it says little about wearable alerting devices in which the sender must know the outcome. We out-lined the main choices for confirmation and forwarding, listed issues particular to worn devices, and reported a single bench observation consistent with feasibility. Quantitative evaluation in the field remains to be done.
