What is ZigBee?

Technology & Standard (global wireless sensing and control network)

Focus Relatively Simple Devices Low cost (open standard, multi-vendor availability)

Low data rate

Low power (years on a AA battery / batteryless)

Robust, reliable, simple deployment and maintenancemesh, self-or anizin , self-healin

Interoperability

True Wireless Networks that Scale (not simply wireless links)



6/35

Purpose of ZigBee

Create a Much Needed Global Wireless sensin and

control network ZigBee gives a voice to the myriad of everyday devices

.

These devices are overlooked in an IT centric world:

Light switches, thermostats, electricity meters

commercial building and industrial automation worlds

Nodes on a Mesh Network

Network Coordinator.

Always on Communicate with multiple

nodes

Network Coordinator

Route message traffic for self

and neighbors

2. Sleepy End Devices (Sensors)

Sleep most of the time

Only route their own traffic

Only communicate with oneline-powered node at a time

Examples of ZigBee in Building

Automation

Sensing

E.g. space sensing for terminal equipment Battery operated

Mesh Networks Self Configuring

Networks automaticall establish robust network

No RF engineering

Each routin node is an

intelligent Sender,Receiver and Router.



27/35

Mesh Networks Self Healing

Multiple redundant paths of communication.

If a pathway is blocked, network automatically reroutes.

Obstruction

Messages hop to their destination. Network automatically adjusts to obstructionsto ensure message gets through.

Wireless BACnet Standard

Two separate tracks to the standardization of BACnet tunneled over

ZigBee :

1. ZigBee in the ASHRAE BACnet committees (SSPC-135)

2. BACnet in the ZigBee Alliance

(Commercial Building Automation group)

Approved
