Wi-SUN FAN Architecture: Border Router, Router Node, LFN and FFN

A role-based architecture walkthrough with practical deployment implications.

Network overview

  • FAN connects meter endpoints through multi-hop mesh to one or more border routers.

Roles in practice

  • Border router anchors control-plane behavior.
  • FFN and LFN strategy must match endpoint power and traffic profile.

Deployment view

  • Route design and node placement are operational decisions, not just planning spreadsheet values.
