Welcome to the Wi-SUN Development Kit user guide. This guide walks you through everything from first steps to advanced features, whether you are new to Digi solutions or an experienced developer. You’ll learn how to configure devices, build Wi-SUN networks, and integrate them into IoT systems.

Wi-SUN in a nutshell

Wi-SUN logo Wi-SUN (Wireless Smart Ubiquitous Network) is a field-proven mesh networking standard designed for large-scale, outdoor, and industrial IoT deployments. It is built on open IEEE and IETF standards and delivers a self-forming, self-healing, and secure wireless mesh using IPv6 over 6LoWPAN.

A Wi-SUN network has the following key characteristics:

  • Standards-based: Uses IEEE 802.15.4g/e and IETF 6LoWPAN/IPv6 standards, ensuring interoperability across vendors and long-term support.

  • Self-forming mesh: Nodes dynamically establish reliable paths without centralized infrastructure.

  • Secure by design: All communication is authenticated and encrypted, with controlled network admission.

  • IPv6-native: Fully compatible with IP networks for direct integration.

  • Low-power optimized: Supports battery and energy-constrained edge devices.

  • Built to scale: Designed to expand from small pilots to large, long-term deployments.

Our solution

Digi’s Wi-SUN solution brings together all the components required to build, operate, and maintain a secure and scalable network. Because the hardware and tools all come from Digi, the system can be deployed and managed as a complete solution, without the challenges of integrating products from different vendors.
This ecosystem reduces complexity, shortens setup time, and ensures that your Wi-SUN deployment can adapt as requirements grow.

Digi’s Wi-SUN solution achieves this through:

  • Hardware products that create and extend the Wi-SUN network like XBee for Wi-SUN and XBee Hive for Wi-SUN devices.

  • Software tools and services that simplify deployment, operation and maintenance like XBee Studio and Digi Remote Manager (DRM).
