Low Power Wide Area Networks (LPWAN) are designed primarily for machine-to-machine communication only. LoRa devices communicate on this network using very small amounts of data and require far less energy than other devices, therefore battery life is long lasting.


Fuel and propane suppliers are able to take advantage of this low cost monitor by monitoring more of their tanks. With larger deployments, marketers have access to a much larger sampling of data, which leads to improved business intelligence and more satisfied customers.
