Why do we care• Zigbee touches the kinetic world more than any other wirless packet technology. •Wifi does not control water spill gate at dam•Bluetooth does not control lighting ,HVAC and application in your office or home.•Manupulating the physical world through wirless introduces newrisks.
•Many of the past mistake is repeat again.

1. A ZigBee network is a multi-hop network with battery-powered devices.2. The set of networking functions that a device performs determines the role of the device in the network and is called a device type.3. The set of parameters that need to be configured to specific values, along with those values, is called a stack profile.4. There are three logical device types in a ZigBee network –(i) Coordinator(ii) Router and(iii) End-device.
Zigbee - Overview
![Page 14: Zig bee](https://reader034.vdocuments.mx/reader034/viewer/2022042714/5495e99fb4795955588b46ef/html5/thumbnails/14.jpg)
Zigbee - Overview(i) Coordinator• This is the device that “starts” a ZigBee network.• It is the first device on the network.• The coordinator node chooses a channel and a network identifier ( also called PAN ID ) and then starts the network.

Zigbee - Overview(ii) Router
• A Router performs functions for(i) allowing other devices to join the network(ii) multi-hop routing

Zigbee - Overview(iii) End Device• An end-device has no specific responsibility for maintaining the networkinfrastructure, so it can sleep and wake up as it chooses.• Thus it can be a battery-powered node.• Generally, the memory requirements (especially RAM requirements) are lower for an end-device.
