Wi-SUN long-range wide-area-network (LPWAN) technology has made significant inroads in IoT networks, smart cities, and smart utilities implementations. Now, Silicon Labs is introducing standards-driven Wi-SUN technology intended to advance new IoT market opportunities and accelerate smart-city application development. Silicon Labs’ certified Wi-SUN solution combines the company’s EFR32 hardware platform, a full-featured IPv6 mesh stack, and advanced development tools to enable secure wireless connectivity for a broad range of applications, from advanced metering infrastructure (AMI) to street lighting networks, asset management, and smart-city sensors such as parking, air quality and waste management.
Wi-SUN is certified by the Wi-SUN Alliance, a global industry association devoted to seamless LPWAN connectivity. Wi-SUN builds upon standard Internet protocols (IP) and APIs, enabling developers to extend existing infrastructure platforms to add new or emerging applications serving a wide range of industrial and smart-city workflows. Built to scale due to its long-range capabilities, high-data throughput and IPv6 support, Wi-SUN simplifies wireless infrastructure for cities and expanding suburban areas
Silicon Labs’ first family of wireless SoCs to support Wi-SUN is EFR32xG12, a 32-bit Arm Cortex-M4 platform with up to 1 MB of flash and 256 kB of RAM as well as an integrated +20 dBm PA for sub-GHz frequencies. Silicon Labs currently has certified Wi-SUN FSK PHYs and is working with lead customers to bring fully-certified Wi-SUN applications to market. General availability of Silicon Labs’ full Wi-SUN solution is expected early summer 2021.
