• Large networks (large number of devices and large coverage area) that can form autonomously and that will operate very reliably for years without any operator intervention

• Very long battery life (years off of a AA cell), very low infrastructure cost (low device & setup costs) and very low complexity and small size

• Device data rate and QoS needs are low

• Standardized protocols are necessary to allow multiple vendors to interoperate

Cluster Tree Networks

• Employ multi-hop routing

• Can be very large: 255 clusters of 254 nodes each = 64,770 nodes

• May span physically large areas

• Suitable for latency-tolerant applications

Slide 21

ZigBeeTM Alliance | Wireless Control That Simply Works

ZigBee Device Types

• ZigBee Coordinator (ZC)– One and only one required for each ZB network.– Initiates network formation.– Acts as 802.15.4 2003 PAN coordinator (FFD).– May act as router once network is formed.

• ZigBee Router (ZR)– Optional network component.– May associate with ZC or with previously associated ZR.– Acts as 802.15.4 2003 coordinator (FFD).– Participates in multihop routing of messages.

• ZigBee End Device (ZED)– Optional network component.– Shall not allow association.– Shall not participate in routing.

ZigBee Channel Access Options

Two channel access mechanisms:• Non-beacon network

– A simple, traditional multiple access system used in simple peer and near-peer networks

– Standard ALOHA CSMA-CA communications– Positive acknowledgement for successfully received packets

• Beacon-enabled network– Superframe structure- network coordinator transmits beacons

at predetermined intervals– Dedicated bandwidth and low latency– Low Power Consumption mode for Coordinator

Slide 26

Wireless Control That Simply Works

ZigBeeTM Alliance | Wireless Control That Simply Works

Other Benefits of Beacon Mode

• Beacon Mode– A very powerful mechanism for controlling power

consumption in extended networks like cluster tree or mesh

– Allows all clients in a local piece of the network the ability to know when to communicate with each other

– PAN has a coordinator that manages the channel and arranges the calls

– Significant value will be in system power consumption for networks which are primarily battery powered

Slide 27

Wireless Control That Simply Works

ZigBeeTM Alliance | Wireless Control That Simply Works

ZigBee – Highly Reliable

• Mesh and tree networking protocol provides redundant paths

• Automatic retries and acknowledgements• Broadcast delivery scheme ensures reliable

broadcasts across the network• Parents keep track of messages for sleeping children• High intrinsic interference tolerance

– Multiple channels– Frequency agility– Robust modulation

Slide 28

Wireless Control That Simply Works

ZigBeeTM Alliance | Wireless Control That Simply Works

ZigBee – Highly Secure

• Utilizes AES 128-bit encryption• Concept of a “trust center”• Link and network keys• Authentication and encryption• Security can be customized for the

application• Keys can be “hard-wired” into application

Patient Monitoring• May allow more patient freedom

– Monitors vital statistics and sends via internet• Patient can remain in their own home• Lowers cost and improves comfort

– Allows monitoring of elderly family member• Sense movement or usage patterns in a home• Notify via mobile phone when anomalies occur• Can track behavior without visual “spying”• Wireless panic buttons for falls or other problems• Again lowers cost and improves patient lifestyle

– Can be used in hospice care• Patients are allowed greater movement• Reduced staff to patient ratio• Light way to bathroom when they get out of bed

– Reduces patient confusion
