Digi International, a leading global provider of Internet of Things (IoT) connectivity solutions, announced the upcoming launch of Digi XBee® for Wi-SUN®, a complete solution designed to accelerate and simplify the deployment of interoperable, secure, and scalable IP-based mesh networks. Tailored for smart city, utility, renewable energy, and industrial IoT applications, this innovation brings new levels of efficiency and resilience to large-scale IoT rollouts.
Wi-SUN: Proven Mesh Networking for Mission-Critical IoT
Wi-SUN (Wireless Smart Ubiquitous Network) is the leading IPv6-based, sub-GHz mesh networking technology built on IEEE 802.15.4g standards and governed by the Wi-SUN Alliance®, a consortium of more than 300 members. With over 100 million devices deployed globally, Wi-SUN networks have demonstrated their reliability in mission-critical environments such as smart grids, utilities, and city infrastructure.
Supporting both battery-powered and infrastructure nodes, Wi-SUN offers flexible data rates from 50 kbps to 2.4 Mbps, adapting to specific application needs. Its open standards-based approach ensures enterprise-grade security, vendor interoperability, and the ability to scale seamlessly from a single site to regional or nationwide networks.

The Digi XBee for Wi-SUN Solution: A Complete, Integrated Ecosystem
All elements of the Digi XBee for Wi-SUN offering are purpose-built to work together:
-
Digi XBee® for Wi-SUN Modules – Powered by Silicon Labs’ EFR32 platform, these modules function as intelligent mesh nodes with built-in MicroPython edge processing and optional Bluetooth LE connectivity for provisioning or sensor integration.
-
Digi XBee Hive™ Border Routers – Cost-effective Wi-SUN gateways featuring integrated connectivity options (LTE, Wi-Fi, Ethernet), container-based edge computing, and IPv6/IPv4 address translation to simplify network integration.
-
Network Management Tools – Digi Remote Manager® provides cloud-based visibility, monitoring, remote updates, managed container deployment, and API-driven enterprise integration. Digi XBee Studio supports local development and field operations.
Built on Wi-SUN’s security foundation, the solution also incorporates Digi TrustFence® with Silicon Labs’ PSA Level 3-certified Secure Vault High™, delivering robust hardware-level protection against cyber threats.
Together, these components enable customers to build, deploy, and manage secure, edge-intelligent Wi-SUN networks at scale.
Industry Collaboration and Commitment to Interoperability
“Solutions like Digi XBee for Wi-SUN are essential in making the advanced capabilities of Wi-SUN broadly accessible,” said Rob Shane, Vice President of Mass Market Sales and Applications at Silicon Labs. “They reduce product development complexity, while allowing customers to focus on delivering innovation in real-world applications.”
Digi’s solution is designed to be fully compatible with the broader Wi-SUN CERTIFIED™ ecosystem, ensuring seamless integration with existing networks. Unique support for Cisco OpenCSMP also opens the door to future interoperability with utility Wi-SUN deployments, creating opportunities for infrastructure sharing that can cut costs and expand use cases for smart cities, utilities, and industrial IoT far beyond traditional metering applications.
“Working with Silicon Labs, we are delivering the industry’s first complete Wi-SUN end-to-end solution that is interoperable and optimized to work seamlessly together from day one,” said Mike Rohrmoser, Vice President of Product Management, OEM Solutions at Digi International. “By combining our expertise, we enable customers across industries to harness the full potential of secure, standards-based IP mesh networking with WI-SUN.”
