What Is Wi-SUN, Really?
A plain-language yet rigorous explanation of Wi-SUN and why it exists in utility communication architecture.

Wi-SUN Knowledge Base
A practical knowledge base for understanding Wi-SUN, RF mesh, IPv6-based utility communication, smart metering networks, and field deployment realities.
I explain utility communication systems from business decision to field implementation — with Wi-SUN, RF mesh, DLMS, IPv6, gateways, HES integration, and deployment realities treated as one connected architecture.

Read articleDecision checklist for utilities and OEMs
- Align communication choice with endpoint density and service-level requirements.
- Validate interoperability across meter, NIC, border router, and HES/MDM before scale-up.
- Treat pilot results as directional; re-test for production traffic and field realities.
- Define firmware, certificate, and network operations ownership before procurement.
- Capture tender assumptions explicitly to reduce post-award architecture drift.
