ZigBee Key facts

A high level communication protocol using small,low-power digital radios based on the IEEE

802.15.4 standard for wireless networks

Up to several hundred (client) nodes per network 16 channels in the global 2.4 GHz band

Full Mesh Networking Support

128bit AES security

Network and link keys can restrict access Easy deployment

Reliable - self forming & self healing

Very long battery life (no new wires)

Low cost

ZigBee Mesh Network - 1

Co-ordinator /FFDRouters/FFDs

Sleepy End Device/RFD Under ZigBee PRO the co-ordinatorestablishes a PAN ID and nodeswithin range effect joining

ZigBee Network Establishment

As routers join a ZigBee PROnetwork they mesh with eachother

ZigBee PRO Network 3

End devices do not haverouting responsibilities innetworks being asleep most

of the time

Assume a routing node isdamaged or lost from the

network

ZigBee Network Healing 6

The loss of a node is notcatastrophic in most ZigBee PROnetworks and may not adverselyaffect the network at all

Co-ordinator /FFD

Routers/FFDs



13/29

ZigBee PRO Network 7

Nodes will seek alternative datapaths back to the co-ordinator. Thisprocess is continuous with ZigBeePRO allowing for a changing radio

environment within a network

ZigBee ProIn October 2007 the ZigBee Alliance announced an expanded set of features

PRO Implements support for larger networks

Multiple methods to simplify routing

ZigBee 2006 uses a tree structure which canlead to address table churning

Stochastic addressing simplifies networkformation

Asymmetric link handling detects asymmetric

links and optimises path selection

Many to one Routing provides a single route ofdiscovery to an aggregation point

Keeps table size small and minimizes routebroadcast giving more bandwidth for data

Embeds routing information in the message

Security upgraded with trust centres Frequency Agility.

Telegesis were first module OEM to offerPRO

Highly recommended for new designs.


17/29

ZigBee Profiles. Application Profiles

Unify data exchange on application level.

Assigned to specific application area

Agreements on device types, messagingformats, actions and functions to be usedin application.

Public profiles are specified by ZigBeeAlliance to provide interoperability between

devices from different manufacturers.

Private profiles are designed by vendorsand used for custom applications

Ensures Network interoperability but does notimply application layer interoperability

Products with the same application profilesinteroperate end to end


18/29

Why Do We Need Profiles?

Need a common language for exchanging data

Need a well defined set of processing actions

Device interoperability across different manufacturers

Simplicity and reliability for the end users

Allows solid test programmes to be created

Add ZigBee easily by usingZigBee Modules

Get your wireless solutions tomarket faster

ZigBee without specialist RF &embedded code skills

All functionality of PRO meshing

technology can be accesses through AT

command layer.

AT+EN Establish PAN

AT+SN Scan Network for other nodes

AT+JN Join next best network

Reduce engineering time

Reduce design risks and focus onyour core strengths.

ZigBee Standards- Looking Forward


25/29

Why a ZigBee IP stack?

The US Congress suggested it in relation toStimulus Funding and Utilities now requiring it as

part of their future networks.

What will most likely be in it? MAC 15.4.2006 with MAC security 6lowPAN packet format and fragmentation ROLL routing

Plus other features essential to effective sensornetworks
