Zigbee: mesh networking for tiny devices

Zigbee (IEEE 802.15.4) is designed for low-power, low-bandwidth IoT devices: sensors, switches, bulbs. Unlike WiFi (which needs a direct router connection), Zigbee devices form a mesh — each device can relay messages for others, extending range and providing redundancy.

Three device types: Coordinator (one per network), Routers (mains-powered, relay traffic), and End Devices (battery-powered, sleep most of the time).
