The Wi-SUN operating specification shown in the table here has a list of standards organized in rows and communication protocols organized in columns. Wi-SUN has significant advantages over other communication protocols, such as: no direct services are needed, worldwide standards, fast data rates, and hopping capabilities. Now, take a look at the other graph on the bottom left of the slide. The horizontal axis is the communication distance, and the vertical axis is the communication speed. Wi-SUN operates at around 100 kB/s at 1 km, which is right in the middle of Wi-Fi and LoRa. It is the most widely used radio in IoT because of its well-balanced specifications. Like Wi-Fi, Wi-SUN is organized by a standardization which allows products to be interoperable. This interoperability ensures Wi-SUN to work great for large-scale networks, and the hopping capability even allows connections in places that have many obstacles.
