What is Wi-SUN?
A practical definition of Wi-SUN FAN for utility leaders, product teams, and field engineers.
Wi-SUN
Wi-SUN Basics
For leaders and teams building baseline understanding before architecture and vendor decisions.
Wi-SUN vs traditional RF mesh
How open IPv6-based mesh differs from proprietary RF systems across scale and interoperability.
Wi-SUN vs LoRaWAN vs NB-IoT
A fit-for-purpose comparison by endpoint density, latency, ownership model, and lifecycle cost.
Why utilities care about open standards
How standards reduce long-term lock-in and improve multi-vendor integration options.
Why Wi-SUN uses IPv6
Addressability, routing, and operations advantages in utility-scale endpoint networks.
Why Wi-SUN matters for AMI
Where Wi-SUN strengthens electricity AMI outcomes and where hybrid designs may still be better.
