Within smart grid and smart city applications, a long-range, reliable mesh topology is critical when creating a robust wide area network that is more immune to interference than other topologies. A self-healing mesh network provides added network redundancy. Our Wi-SUN® solutions include our pin-to-pin compatible wireless microcontroller (MCU) family that enables low-power, cost-effective communication for large-scale outdoor networks with thousands of nodes.
