!!! Device types

Zigbee defines three different device types: coordinator, router, and end device.
!! Zigbee Coordinator
Zigbee networks may only have a single [Zigbee Coordinator] device. This device:
* Starts the network, selecting the channel and PAN ID (both 64-bit and 16-bit).
* Buffers wireless data packets for sleeping end device children.
* Manages the other functions that define the network, secure it, and keep it healthy.
* Cannot sleep; the coordinator must be powered on all the time.
!! [{$pagename}] Router
A [ZigBee Router] is a full-featured Zigbee node. This device:
* Can join existing networks and send, receive, and route information. Routing involves acting as a messenger for communications between other devices that are too far apart to convey information on their own.
* Can buffer wireless data packets for sleeping end device children. Can allow other routers and end devices to join the network.
* Cannot sleep; router(s) must be powered on all the time.
* May have multiple router devices in a network.
!! End device
An end device is essentially a reduced version of a router. This device:
* Can join existing networks and send and receive information, but cannot act as messenger between any other devices.
* Cannot allow other devices to join the network.
* Uses less expensive hardware and can power itself down intermittently, saving energy by temporarily entering a non responsive sleep mode.
* Always needs a [ZigBee Router] or the coordinator to be its parent device. The parent helps end devices join the network, and stores messages for them when they are asleep.
Zigbee networks may have any number of end devices. In fact, a network can be composed of one Zigbee Coordinator, multiple end devices, and zero [ZigBee Routers].
