Wi-SUN, the full name of Wireless Utility Networks, translated into Chinese as intelligent wireless network, is the collective name for a series of standard wireless communication networks based on IEEE 802.15.4 as the underlying protocol. Every device in a Wi-SUN network can communicate with neighboring devices. Wi-SUN mainly includes Wi-SUN FAN (Wireless Utility Field Area Network) and Wi-SUN HAN (Wireless Home Area Network).
Compared with Wireless Module using the 2.4GHz and 5GHz frequency bands, although Wi-SUN has slower communication speed, it has the advantages of low cost, long communication distance, ability to bypass obstacles and easy connection, and low power consumption. Through the integration of Mesh networking and active frequency hopping technology, Wi-SUN can be deployed in a separate area or complement other IoT technologies, reducing overall construction and operating costs.
Wireless network technology comparison:
Wi-SUN is a network protocol based on a mesh topology, unlike star-based Wi-Fi or LTE. Wi-SUN supports star, mesh and hybrid topologies. Wi-SUN is typically deployed in a mesh architecture, where each node relays data to the network. Additionally, Wi-SUN devices operate on AC power and battery power.
Three characteristics of Wi-SUN technology:
1. Interoperability
In 2018, the Wi-SUN Alliance launched the Outdoor Area Network (FAN) Interoperability Certification Program, which is tested by a third-party testing laboratory to verify whether the product equipment complies with the IEEE 802.15.4g standard and interoperates with equipment from other manufacturers. Certified equipment can be used in all Wi-SUN network deployments at home and abroad.
2. Broadness and scalability
Wi-SUN’s mesh network can be expanded in capacity and quantity. Wi-SUN FAN is compatible with millions of devices.
3. Security
Enterprise-level security certification, IP-based device authentication and encrypted communication technology ensure the security of the Wi-SUN network.

Wi-SUN profile
Founded in 2012, the Wi-SUN Alliance currently has 200 members including Cisco, ARM, and Texas Instruments (TI), and has jointly launched more than 100 Wi-SUN certified products, with more than 95 million deployed worldwide. a Wi-SUN-enabled device. Low-power wireless communication Grow the Wi-SUN ecosystem by leveraging the open global standard IEEE 802.15.4g to provide robust product connectivity through testing and certification programs.
Wi-SUN is a communication method that complies with the IEEE 802.15.4g standard. It is based on IEEE 802.15.4g as the underlying protocol, and its upper-layer configuration files depend on the application. The creation of Wi-SUN profiles, certification to ensure interconnectivity and its popularization activities are implemented by the Wi-SUN Alliance.
