The Wi-SUN Alliance, the global ecosystem promoting open, secure, and interoperable wireless mesh for utilities Wireless Mesh Network.
The Wi-SUN FAN (Field Area Network) specification has become the first wireless mesh networking standard to be adopted by ISO/IEC, setting a new benchmark for interoperable, secure, and scalable communications. This achievement is expected to accelerate the adoption of smart utilities, smart cities, industrial IoT, and critical infrastructure worldwide.
“When a specification carries ISO/IEC recognition, it signals to procurement officials, regulators and policymakers around the world that the technology has been vetted at the highest level,” said Phil Beecher, president and CEO of the Wi-SUN Alliance. “Wi-SUN technology already supports some of the world’s largest utility networks, including nationwide smart metering deployments in Japan and large-scale smart grid projects across North America, Europe and Asia-Pacific, demonstrating that the technology is already proven at scale. ISO/IEC/IEEE 32857:2026 gives utilities, municipalities and infrastructure providers an internationally recognized standard they can rely on and reference when planning the next generation of critical infrastructure.”
