Wireless Smart Ubiquitous Network (Wi-SUN) is the leading IPv6 sub-GHz mesh technology for smart city and smart utility applications. Wi-SUN brings Smart Ubiquitous Networks to service providers, utilities, municipalities/local government, and other enterprises, by enabling interoperable, multi-service, and secure wireless mesh networks. Wi-SUN can be used for large-scale outdoor IoT wireless communication networks in a wide range of applications covering both line-powered and battery-powered nodes.
Silicon Labs' Wi-SUN hardware is certified by the Wi-SUN Alliance, a global industry association devoted to seamless LPWAN connectivity. Wi-SUN builds upon open standard internet protocols (IP) and APIs, enabling developers to extend existing infrastructure platforms to add new capabilities. Built to scale with long-range capabilities, high-data throughput and IPv6 support, Wi-SUN simplifies wireless infrastructure for industrial applications and the evolution of smart cities.

Kits and Boards
Wi-SUN Development Kits
Silicon Labs Wi-SUN Wireless Starter Kits support 868-915 MHz and is an ideal development platform for getting familiar with EFR32 FG12 and MG12 wireless SoCs. The kits provide all necessary tools for developing scalable, secure Wi-SUN IoT Applications. Radio boards supporting other Wi-SUN frequency bands can be ordered separately.
The Wireless Starter Kit Mainboard contains an on-board J-Link debugger with a Packet Trace Interface and a virtual COM port, enabling application development and debugging of the attached radio board as well as external hardware. The mainboard also contains sensors and peripherals for easy demonstration of some of the EFR32's many capabilities.
