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. Ideal for a wide range of IoT applications, from agricultural to asset management, Wi-SUN is a powerful solution based on 3 main benefits:

  • Ubiquitious & Scalable. Wi-SUN-based mesh networks have proven themselves for years in a range of harsh and remote environments across the globe. Tens of millions of reliably connected endpoints demonstrate that a Wi-SUN-based IoT mesh network can achieve the ubiquity and scalability many IoT customers demand.
  • Freedom. When an IoT network complies with industry standards like IEEE 802.15.4g, you as a network owner or operator will gain advantages. One of the biggest advantages is that you are not locked into solutions from a single vendor.
  • Security. Supports the latest IP-based security technologies for device authentication and encrypted communications. Wi-SUN Alliance member companies are deploying globally tens of millions of compatible IoT devices so it is essential that a Certificate Authority can operate at this scale.

With native support for the IEEE 802.15.4g packet format, our high-performance ultra-low-power S2-LP RF transceiver is Wi-SUN ready.

To help developers find the best fit for their applications, ST offers a wide range of ultra-low-power sub-1GHz multi-channel RF modules based on the S2-LP transceiver as well as a complete development ecosystem with evaluation boards, software tools, firmware and application notes to help reduce development time and costs.
