Customers can reap the benefits of new capabilities of Wi-SUN FAN 1.1
With over 100 merchandise licensed by the Wi-SUN Alliance, Field Area Network 1.0 is a well-liked networking possibility for sensible utility and sensible metropolis use circumstances. Electric utility metering, distribution automation, and municipal avenue lighting purposes profit drastically from FAN’s safe, self-forming, self-healing IPv6 wi-fi mesh networking which is ready to assist million scale deployments spanning giant geographic areas.
Building on the robust basis laid down by FAN 1.0, the Wi-SUN Alliance lately introduced the supply of the primary gadgets licensed to assist the brand new characteristic additions of FAN 1.1. These new FAN 1.1 capabilities embody:
- Low vitality system operation (LE). Low energy nodes are in a position to operate for as much as 20 years on a single battery cost, focusing on use circumstances corresponding to methane detection, water metering, fuel metering, and different low energy discipline sensing purposes.
- Higher efficiency (HP). FAN 1.1 provides Orthogonal Frequency Division Multiplexing radio assist, which means FAN 1.1 now affords knowledge charges from 50 Kbps (FSK) as much as 2.4 Mbps (OFDM). The increased knowledge charges are perfect for utility AMI 2.0 and Distribution Automation use circumstances corresponding to Fault Location Isolation and Restoration (FLISR).
- Modulations and knowledge charge negotiation (MDR). Mesh neighbors can now negotiate a “gear shift” to transition, for instance, a bit of a decrease pace AMI mesh to a better throughput mode for DA fault isolation operations.
- Expanded geographic assist. North America, Brazil, Japan, and European Union operation is supported. Extension to extra 800 and 900 MHz areas is now sensible.
Figure 1 depicts an instance multi-hop FAN 1.1 mesh. The mesh types routinely between a set of deployed Routers and a Border Router offering WAN connectivity. A Router’s frequency hopping capabilities and skill to find out alternate knowledge paths present superior resiliency. Routers are additional in a position to “parent” low energy nodes.

The sub-GHz mesh RF hyperlinks can individually stretch to a number of kilometers (relying upon native circumstances), with multi-hop meshes in a position to span distances of 10s of kilometers. A single FAN 1.1 mesh can assist hundreds of Router nodes, every in a position to guardian low energy nodes. A traditional utility deployment state of affairs is an electrical meters (Router) parenting a number of low energy water meters, fuel meters, or environmental sensors. Adding extra meshes scales a deployment to tens of millions of nodes.
The Catalyst IR8100 Heavy Duty Series Industrial Router would be the first member of the Cisco Resilient Mesh resolution to be FAN 1.1 licensed. Given its rugged design for harsh out of doors environments, versatile backhaul configuration, and safety capabilities, the IR8140 is a perfect FAN 1.1 Border Router. An particular person IR8140 can root a mesh of hundreds of FAN 1.1 gadgets, with tens of millions scale system networks achieved with the deployment of extra IR8140s. Following the IR8140, IR530 Range Extender, and Cisco Resilient Mesh Endpoint SDK may also be scheduled for FAN 1.1 certification, rounding out a whole Cisco FAN 1.1 portfolio of Border Routers, Routers, and endpoint design SDK.

Large FAN 1.1 networks require a community administration system in a position to present lifecycle administration for million node networks. Cisco IoT Field Network Director is objective constructed, and discipline confirmed to handle these large-scale networks.
“Wi-SUN 1.1 provides improved flexibility, security, and adaptive performance to unlock newer markets demanding high performance or low energy use cases in the growing Utility or Smart city landscape. Cisco’s Wi-SUN commitment has been focused on ease of use through simplified Zero Touch Provisioning, resiliency in varying RF conditions, interoperability and network management for endpoints and border routers through industry leading OpenCSMP to enable customers to build production networks with its industry leading solution at scale in a secure manner.” says Lakshmi Narayana Jammi, Sr Product Manager for Cisco IR8140 and Cisco Resilient Mesh SDK
“With the introduction of low power nodes and higher data rates, FAN 1.1 supports many new and exciting use cases. Cisco is well positioned to support this increase in utility and smart city network demand with OpenCSMP and Field Network Director, device and network management solutions that have proven ability to scale to millions of endpoints.” says Clay Stroud, Product Manager for Cisco Field Network Director.
“Wi-SUN FAN1.1 provides highly flexible communications capability allowing both high performance and low energy functionality on the same network, making it the obvious choice for an even broader range of industrial IoT applications such as utilities and smart cities” says Phil Beecher, President and CEO of the Wi-SUN Alliance. “We’re excited that Cisco shall be supporting Wi-SUN FAN 1.1 communications infrastructure with its vary of business routers, bringing confirmed reliability, scalability, and safety to those crucial infrastructure networks. “
