Wi-SUN

Wi-SUN is a global wireless networking standard developed for large scale outdoor and industrial IoT deployments such as smart metering, smart grids, smart cities and utility infrastructure.

Overview

Maintained and certified by the Wi-SUN Alliance, this standard is designed specifically for:

  • Long range communication
  • High device density
  • Self healing mesh networks
  • Secure, low power operations in harsh environments

Unlike short range IoT protocols, Wi-SUN supports carrier grade reliability and utility scale deployments.

Deployment Use Cases

Wi-SUN networks are widely deployed for:

  • Smart electricity, gas and water metering
  • Street lighting automation
  • Distribution grid monitoring
  • Environmental and city infrastructure sensors
  • Utility field area networks

It enables thousands of devices to communicate securely over wide geographic areas without relying on cellular networks.

Technical Architecture

Wi-SUN is built on IPv6 based mesh networking and supports:

  • Automatic node discovery and routing
  • Scalable multi hop communication
  • High availability through self healing paths
  • Interoperability between certified vendors
  • End to end IP connectivity for backend integration
