How many layers does zigbee consist of
WebHow Zigbee Works. A typical Zigbee network contains three different types of devices: a coordinator, routers, and end devices. These devices work with each to deliver messages and instructions from the central coordinator out to the individual end devices, like a light bulb. The coordinator is the most capable device and sits at the root of the ... Web25 nov. 2024 · For one of the projects, we have compared the main characteristics of BLE 5.x Mesh, Zigbee, Thread, and our own Integra BLE networks. BLE mesh network had the lowest bandwidth, less than 1.5 kbit/sec for 100 bytes packet on six hops, and the largest delay (640 ms for the same packet and four hops).
