Lisa Taubensee Texas Instruments May 26, 2011 Introduction to Zigbee

Agenda – Zigbee Market – Target Customers – Applications – TI Zigbee Offerings – Zigbee Protocol

Zigbee The Zigbee Alliance has a growing membership well over 200 Volumes of nodes in the millions is the expectation as Zigbee becomes adopted and further integrated into products

Where Does ZigBee Fit? Range Peak Data Rate CloserFarther Slower Faster UWB Wireless Data Applications Sources: WRH + Co Wireless Video Applications IrDA g b a 2.5G/3G Bluetooth™ ZigBee™ Wireless Sensors Wireless Networking Wi-Fi®

Zigbee Applications Smart Energy - metering Health – medical, sport Building and Home automation Sensor Networks Consumer Electronics Remote control

Zigbee in the Home

Zigbee Low power/data applications Self healing mesh network Supports large networks Sleeping Devices 2.45GHz worldwide standard DSSS (Direct sequence spread spectrum) Channel Change, but no frequency hopping

Radio Protocols Defines how two radios communicate with each other Frequency Permission for network joining/Security Permission to send Send/receive timing Data Format/Length Interoperability

2.45 GHz Band 250kbps Data Rate Various security options with built in AES-128 encryption engine Ability to change channel upon detecting interference Supports Sleeping devices and store and forward Mesh network Built on IEEE bit IEEE Address together with a 16-bit short address allowing approx nodes in a network Built for interoperability (TI produces one of 3 golden modules) as a worldwide standard Three device types – coordinator, router and end device (preprogrammed) Profile Based Zigbee Practical Information

Zigbee is composed of profiles, one example is the smart energy profile. A profile adds the final step to the protocol and final details of how the devices behave and communicate. A profile defines the language the devices speak. For example „Dim Light“ or „Increase Temperature“. This part of making interoperability as well as allowing service discovery and compatibility checks What is a Profile?

The Zigbee Mesh

Devices that loose the network can attempt to rejoin Dynamic routing that has the potential to overcome problems at a node Multiple hops between devices Routing tables and route discovery Various binding types Store and forward allowed from parent devices Why Mesh?

Zigbee Pros and Cons PROS Mesh Worldwide Low power Standard CONS Low data rate Less flexibility Slow adaptation Crowded frequency band Competing technologies
