The Wi-SUN Alliance is a global member-based industry association. Founded in 2012 by Promoter Members, including Analog, Devices Cisco, Itron, Murata NICT, Omron, Renesas, Rohm Semiconductor, Silver Spring Networks and Toshiba, Wi-SUN's goal is to drive the adoption of wireless solutions in markets serving the Internet of Things (IoT).
The Wi-SUN Alliance seeks to accelerate the implementation of smart grids, smart cities, smart utilities and large-scale outdoor IoT applications by enabling the global adoption of interoperable solutions based on open standards.
It creates communications layer specifications based on open standards from organisations, such as IEEE802, IETF, TIA, TTC and ETSI, and develops a robust testing and certification program guaranteeing that products that implement the Wi-SUN specification interoperate. The Alliance has certified around 80 products worldwide, including many for the connection of smart meters to home energy management systems.
Wi-SUN specifications bring 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, including:
• Smart grid - e.g. advanced metering infrastructure, Peak Load Management, control of power distribution, alternative energy, e.g. control of solar and wind farms
• Smart cities - e.g. street lighting, dynamic control of traffic lights, smart parking
• Structural health monitoring - e.g. monitoring of the integrity of bridges, buildings, etc.
• Agriculture - e.g. monitoring humidity and temperatures in greenhouses.
Wi-SUN smart cities include Copenhagen, Paris and Stockholm, while Bristol has become the first Wi-SUN-powered smart city in the UK.
