Long range, years on batteries
LoRa radio reaches several kilometres in cities and more in open terrain, and sensors that report every few minutes run for years on batteries. That removes trenches and cabling for points that are far apart.
Small payloads, minutes not milliseconds
Each uplink carries a few dozen bytes, and radio duty-cycle rules (1% in most EU868 sub-bands) limit how often a device can talk. Readings every 5 to 15 minutes are typical; alarms can be sent at once when a threshold is crossed.
The network server decodes
Gateways only relay radio packets. The network server (TTN, ChirpStack, Actility ThingPark, LORIOT) authenticates devices, removes duplicates and runs the payload decoder that turns bytes into values such as temperature or level.
The SCADA supervises
The SCADA or IoT platform receives decoded values over MQTT or HTTP, shows them on synoptics and maps, raises and escalates alarms, stores history and reports, and can mix them with Modbus and OPC UA data from the plant.
