!!! Overview
[{$pagename}] is an [IEEE 802.15.4]-based specification for a suite of high-level [communication] [protocols] used to create [Personal Area Networks] with small, [low-power|Lo] [digital radios|Wireless], such as for home automation, medical [device] data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. 


[{$pagename}] is a [Low-Power and Lossy Network], with low data rate, and [Wireless Network] for [Personal Area Networks]


[{$pagename}] [networks] are [Personal Area Networks] (or PANs). Each [{$pagename}] network is defined with a unique PAN identifier ([Zigbee PAN ID]), which is common among all devices of the same network. [{$pagename}] devices are either preconfigured with a PAN ID to join, or they can discover nearby networks and select a PAN ID to join.

[{$pagename}] supports both a 64-[bit] and a 16-bit PAN ID. Both PAN IDs are used to uniquely identify a network. [Devices] on the same Zigbee network must share the same 64-bit and 16-bit PAN IDs. If multiple [Zigbee Network]s are operating within range of each other, each [MUST] have unique PAN IDs.


!! [Zigbee Network] [Device] types

Zigbee defines three different device types: 
* [Zigbee Coordinator]
* [Zigbee Router]
* [Zigbee 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].
