ZigBee standard uniquely fills a gap for low data rate applications



• Networks that can form by themselves, scale to large sizes and 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

Sensor/Control Network Requirements



ZigBee Alliance Overview-

• Organized as an independent, neutral, nonprofit corporation in 2002

• Open and global• Anyone can join and participate• Membership is from all over the world

• Activity includes • Specification creation• Certification and compliance programs • Branding, market development, and user education



The ZigBee Alliance --• Is a growing community of companies

• ~200 members vs. 35 Dec. 2002 (5+X Growth)• Includes major names in the Semiconductor, Software

Developer, End Product Manufacturer, and Service Provider Industries including major Telecom Carriers

• Has made its specification publicly available• ZigBee is open to all• 32,000+ downloads to date

• Has announced its 19th compliant platform• ZigBee is all about multi-source with no dominating

elements or companies• Watch for news at www.zigbee.org

ZigBee Mesh Networking



ZigBee – Highly Reliable

• Mesh networking protocol provides redundant paths• Automatic retries and acknowledgements• Parents keep track of messages for sleeping children• High intrinsic interference tolerance

– Multiple channels– Supports Frequency agility– Robust modulation



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



Application Examples



Home Awareness

Home Heartbeat



Home Entertainment & Control



In-Home Patient Monitoring

• Patients receive better care at reduced cost with more freedom and comfort---– Patients can remain in their own home

• Monitors vital statistics and sends via internet• Doctors can adjust medication levels

– Allows monitoring of elderly family member• Sense movement or usage patterns in a home• Turns lights on when they get out of bed• Notify via mobile phone when anomalies occur• Wireless panic buttons for falls or other problems

– Can also be used in hospital care• Patients are allowed greater movement• Reduced staff to patient ratio

Lighting Control

• Wireless lighting control– Dimmable ballasts– Light switches anywhere– Customizable lighting schemes– Energy management– Dali [or other] interface to BMS

• Extendable networks– Additional sensors– Other networks



HVAC Energy Management

• Hotel energy management– Centralized HVAC

management allow hotel operator to make sure empty rooms are not cooled

– Easy to Retrofit– Battery operated

thermostats, occupancy detectors, humidistats can be placed for convenience

– Personalized room settings at check-in



Building ControlStudies show that wiring alone can account for 20% to

80% of the cost for a control point in HVAC or lighting networks.

What if you could reduce that cost to nearly zero in many cases?

And what if you could achieve superior building performance at the same time?

TAC has made the promise of wireless a reality for building owners. Our broad line of wireless enabled controllers allows building owners and facility managers to improve building control while dramatically reducing costs.

The TAC wireless solution is based on the Andover Continuum family of controllers, proven in more than 40,000 buildings around the world. Fully open and standards-based, TAC’s wireless solution can be deployed easily, wherever needed, alongside existing networks and systems. What’s more, TAC provides a powerful and graphical management tool so you can see and manage the entire wireless network based on real-time information. It’s the kind of highly reliable and cost-effective building control solution thousands of customers worldwide have come to expect from TAC.

Only now, no wires are needed.



Mobile Handset as ZigBee Gateway

• Use mobile handset as a gateway to collect and display information

• In a mobile phone a ZigBee enabled SIM, the personal token, can play the Gateway role
