ChirpStack

ChirpStack is an open-source solution for building private or public LoRaWAN networks. It enables organizations to connect long-range, low-power devices—such as sensors and meters—and manage them through an easy-to-use interface. ChirpStack simplifies the process of running secure IoT networks while offering flexibility to integrate with existing business systems.

LoRaWAN Network​

LoRaWAN is a low-power, wide-area network (LPWAN) protocol built on top of the LoRa modulation. It is specifically designed for Internet of Things (IoT) applications. LoRa modulation is based on chirp spread spectrum (CSS), which enables long-range connectivity, resistance to interference, and operation with very low power consumption.

Devices and Gateways​

End devices, such as sensors or actuators, are typically battery-powered and communicate using LoRa modulation. These devices transmit messages using an ALOHA-based protocol, meaning they send data whenever they need to, and any gateway within range can receive it. Gateways then act as packet forwarders, relaying received messages over IP (via Ethernet, Wi-Fi, or cellular) to the network server.

Network Server​

The Network Server is the central intelligence of a LoRaWAN network. It:

  • Authenticates and manages devices.
  • Deduplicates messages when several gateways receive the same transmission.
  • Determines the best gateway path for downlinks.
  • Enforces end-to-end security using AES-128 encryption.

Application Layer​

After processing, the Network Server forwards the messages to the Application Server. Here the data can be visualized on dashboards, integrated into cloud applications, or used to trigger automation workflows.

Topology and Use Cases​

LoRaWAN follows a star-of-stars topology, where end devices connect to multiple gateways, and those gateways are connected to a central server. This architecture is ideal for applications that require long range, low power consumption, and small, infrequent messages. Typical use cases include smart agriculture, smart cities, asset tracking, utility metering, and industrial monitoring.
