Architecture and Concepts


LoRaWAN is a type of wireless wide-area networking that is designed to allow long-range communication at a low bit rate among low-power connected objects, such as sensors operated on a battery.

Network topology is of star-of-stars type, with the leaf sensors sending data to gateways for forwarding telemetry to and receiving commands from backing Internet services. Nowadays, even for simple scenarios like having 10 devices connected to a single LoRaWan gateway (hardware with antenna), you need to connect your gateway to a Network Server and then work through connectors provided by the server vendor to integrate your LoRa gateways and devices with the back end. These setups can be connected to Azure IoT Hub quite easily. As a matter of fact such scenarios exist. Customers looking for an operated network with national or international reach (e.g. fleet operators, logistics) will tend to choose this setup accepting the potentially higher complexity and dependency on the network operator.

However, customers looking for any of the following are expected to prefer a setup where the LoRaWAN network servers runs directly on the gateway/Azure IoT Edge:

  • Primarily coverage on their own ground (e.g. manufacturing plants, smart buildings, facilities, ports).
  • Capabilities that Azure IoT edge brings to the table:
    • Local processing on the gateway.
    • Offline capabilities of the gateway.
    • Gateway management.
  • Homogenous management of devices and gateways independent of connectivity technology.
