The Wireless Smart Utility Network for Field Area Network (Wi-SUN FAN) profile is generally known as a wireless communication standard for Advanced Metering Infrastructure (AMI). It is gathering attention for use in other applications such as smart cities and smart grids. Currently, Wi-SUN FAN is used to remotely access infrastructure such as sensing, lighting and building automation by building a large-scale mesh network.
A unique property of mesh networks is their node to node routing function. Self-configuration by multi-hopping provides dynamic distribution of workloads especially when a few nodes fail. Adding nodes becomes easier even when hundreds of nodes are already deployed making Wi-SUN FAN an optimal solution for smart cities and smart grids.
Renesas' reference design for Wi-SUN router applications can scale from a simple low-cost node implementation to a high-performance sensing and automation solution. The reference design includes the protocol stack for Wi-SUN FAN to ease implementation and certification.
