Wi-SUN Architecture

For solution architects and program owners designing scalable utility communication systems.

Wi-SUN FAN architecture

End-to-end view from smart meter NIC to border router to HES/MDM layers.

Border Router role

Routing domain boundary, policy control, and telemetry bridging into utility backend networks.

Router Node and relay behavior

How routing nodes influence path quality, latency, and network stability.

LFN and FFN planning

Power and traffic profiles, role assignment strategy, and operational implications.

IPv6, 6LoWPAN, and RPL

Core protocol stack decisions that shape scale behavior in field networks.

UDP, CoAP, and DLMS integration

Transport and application considerations for meter data and command workflows.

Security and certificates

Identity, onboarding, and lifecycle management of secure utility communication domains.

HES/MDM integration patterns

What backend teams must design early to avoid operational bottlenecks later.
