2 Agenda & the Aim of this Presentation Agenda Basic ZigBee concepts What s in a ZigBee node? ZigBee Profiles How to add ZigBee to your designs ZigBee in the Future Aims of this Presentation To give you an basic understanding of ZigBee Introduce Mesh networking concepts What you need to consider when adding ZigBee Understand if ZigBee is suitable for your next design How you can include ZigBee in your next design. Show you where ZigBee is headed

ZigBee Key facts A high level communication protocol using small, low-power digital radios based on the IEEE 802.15.

3 ZigBee Key facts A high level communication protocol using small, low-power digital radios based on the IEEE standard for wireless networks Up to 65,536 (client) nodes per network 16 channels in the global 2.4 GHz band Full Mesh Networking Support 128bit AES security Easy deployment Reliable - self forming & self healing Very long battery life (no new wires) Secure (128 bit encryption) Low cost

4 Where does ZigBee fit? TEXT INTERNET/AUDIO COMPRESSED VIDEO MULTI-CHANNEL DIGITAL VIDEO SHORT < RANGE > LONG Range over 1.5Km with PA module ZigBee b /WIMEDIA a/HL2 & g Bluetooth 2 Bluetooth1 LOW < ACTUAL THROUGHPUT > HIGH

6 Star vs Meshing Wi-Fi,Bluetooth,GSM ZigBee

7 ZigBee Mesh Network - 1 Co-ordinator /FFD Routers/FFDs Sleepy End Device/RFD Under ZigBee PRO the co-ordinator establishes a PAN ID and nodes within range effect joining

8 ZigBee Network Establishment Co-ordinator /FFD Routers/FFDs Sleepy End Device/RFD As routers join a ZigBee PRO network they mesh with each other

9 ZigBee PRO Network 3 Co-ordinator /FFD Routers/FFDs Sleepy End Device/RFD End devices do not have routing responsibilities in networks being asleep most of the time

10 ZigBee Network 4 Co-ordinator /FFD Routers/FFDs Sleepy End Device/RFD The resulting network is very robust and reliable

11 ZigBee Network 5 Co-ordinator /FFD Routers/FFDs Sleepy End Device/RFD Assume a routing node is damaged or lost from the network

12 ZigBee Network Healing 6 Co-ordinator /FFD Routers/FFDs Sleepy End Device/RFD The loss of a node is not catastrophic in most ZigBee PRO networks and may not adversely affect the network at all

13 ZigBee PRO Network 7 Co-ordinator /FFD Routers/FFDs Sleepy End Device/RFD Nodes will seek alternative data paths back to the co-ordinator. This process is continuous with ZigBee PRO allowing for a changing radio environment within a network

14 Typical ZigBee PRO network End devices, typically battery powered Routers, typically mains powered Mesh Link Star Link Co-ordinator Co-ordinator /FFD Router/FFD Sleepy End Device/RFD Mixed Star and Mesh topologies

16 ZigBee Pro In 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 can lead to address table churning Stochastic addressing simplifies network formation Asymmetric link handling detects asymmetric links and then optimising path selection Many to one Routing provides a single route of discovery to an aggregation point Keeps table size small and minimizes route broadcast giving more bandwidth for data Security upgraded with trust centres Frequency Agility. Telegesis were first module OEM to offer PRO Highly recommended for new designs.

Alliance in order to provide interoperability

Private profiles are designed by vendors and

interoperability but does not imply application

17 Application Profiles ZigBee Profiles. Unify data exchange on application level. Assigned to specific application area Agreements on device types, messaging formats, actions and functions to be used in application. Public profiles are specified by ZigBee Alliance in order to provide interoperability between devices from different manufacturers. Private profiles are designed by vendors and used for custom applications Ensures Network interoperability but does not imply application layer interoperability Products with the same application profiles interoperate end to end

18 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 Consumer flexibility for products Allows solid conformance test programmes to be created Realistic application specifications developed through OEM experience
