3 The IEEE 802 Wireless Space WWAN IEEE Range WMAN WLAN WPAN ZigBee c Bluetooth IEEE WiMax IEEE WiFi c ZigBee standard uniquely fills a gap Data Rate (Mbps) for low data rate applications ZigBee TM Alliance Slide 3

4 Sensor/Control Network Requirements 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 ZigBee TM Alliance Slide 4

5 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 ZigBee TM Alliance Slide 5

6 The ZigBee Alliance -- Is a growing community of companies ~200 members vs. 35 Dec (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 19 th compliant platform ZigBee is all about multi-source with no dominating elements or companies Watch for news at ZigBee TM Alliance Slide 6

21 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 graphic graphic ZigBee TM Alliance Slide 21

22 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 ZigBee TM Alliance Slide 22

23 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 ZigBee TM Alliance Slide 23

24 Building Control Studies 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.
