Smart Utility Networks

Wi-SUN technology is bringing Smart Utility Networks to enterprises, service providers and municipalities by enabling interoperable, multi-service and secure IPv6 communications over an IEEE 802.15.4g  based wireless mesh network.

Wi-SUN enables large-scale outdoor IoT networks including applications like advanced metering infrastructure and distribution automation.

Wi-SUN is delivering mesh-enabled field area networks (FAN) to provide resilient, secure and cost-effective connectivity with ubiquitous coverage in a range of topographical environments, from dense urban neighbourhoods to rural areas, with minimal additional infrastructure. 

What are the benefits?

Future Proofing

Offers utilities, cities and service providers adaptable multi-service networks that will help ensure interoperability today, and for future generations.

Time Saving

Reduces the time needed to evaluate new products, as behavior and interoperability are well defined.


Encourages the development of a global ecosystem of standards-based products, reducing the risk and costly impact of stranded assets.

Wi-SUN is proven in the world’s largest outdoor IoT Networks. More than 96.5 million Wi-SUN capable devices awarded worldwide.
