14. Month Year Copyright 2003 The ZigBee Alliance, Inc. 14 Mesh networks overcome barriers to wireless adoption Barrier #1: reliability People can move when wireless reception is poor; machines typically cannot Humans tolerate garbled communication; machines do not Barrier #2: wireless expertise Customers (and some installers) do not want to become wireless experts Want “wireless control that simply works”

15. Month Year Copyright 2003 The ZigBee Alliance, Inc. 15 Why ZigBee? Reliable and self healing Supports large number of nodes Easy to deploy Very long battery life Secure Low cost Can be used globally

16. Month Year Copyright 2003 The ZigBee Alliance, Inc. 16 Advantages of ZigBee over proprietary solutions? Product interoperability Vendor independence Increased product innovation as a result of industry standardization A common platform is more cost effective than creating a new proprietary solution from scratch every time Companies can focus their energies on finding and serving customers

26. ZigBee and Bluetooth Competitive or Complementary?

27. Month Year Copyright 2003 The ZigBee Alliance, Inc. 27 Bluetooth is a cable replacement for items like Phones, Laptop Computers, Headsets Bluetooth expects regular charging –Target is to use <10% of host power ZigBee and Bluetooth Address Different Needs

28. Month Year Copyright 2003 The ZigBee Alliance, Inc. 28 ZigBee is better for devices Where the battery is ‘rarely’ replaced –Targets are : Devices where only a tiny fraction of host power is available New opportunities where wireless not yet used ZigBee and Bluetooth Address Different Needs

29. Month Year Copyright 2003 The ZigBee Alliance, Inc. 29 ZigBee and Bluetooth ZigBee –Smaller packets over large network –Mostly Static networks with many, infrequently used devices –Rapid Network Join Bluetooth –Larger packets over small network –Ad-hoc networks –Long Network Join Times Optimized for different applications

30. Month Year Copyright 2003 The ZigBee Alliance, Inc. 30 Bluetooth: Network join time = >3s Sleeping slave changing to active = 3s typically Active slave channel access time = 2ms typically Timing Considerations ZigBee protocol is optimized for timing critical applications ZigBee and Bluetooth ZigBee: Network join time = 30ms typically Sleeping slave changing to active = 15ms typically Active slave channel access time = 15ms typically

32. Month Year Copyright 2003 The ZigBee Alliance, Inc. 32 A Light Switch Example Wireless Light switch – –Easy for Builders to Install A Bluetooth Implementation would either : – keep a counter running so that it could predict which hop frequency the light would have reached or –use the inquiry procedure to find the light each time the switch was operated. Battery Life & Latency in a Light Switch

33. Month Year Copyright 2003 The ZigBee Alliance, Inc. 33 Light switch using Bluetooth Option 1: use counter to predict hop frequency reached by light –The two devices must stay within 60 us (~1/10 of a hop) –With 30ppm crystals, devices need to communicate once a second to track each other's clocks. –Assume this could be improved by a factor of 100 then devices would need to communicate once every 100 seconds to maintain synchronization. –=> 900 communications / day with no information transfer + perhaps 4 communications on demand –99.5% Battery Power wasted

34. Month Year Copyright 2003 The ZigBee Alliance, Inc. 34 Light switch using Bluetooth Option 2: Inquiry procedure to locate light each time switch is operated –Bluetooth 1.1 = up to 10 seconds typical –Bluetooth 1.2 = several seconds even if optimized –Unacceptable latency

35. Month Year Copyright 2003 The ZigBee Alliance, Inc. 35 Light switch using ZigBee With DSSS interface, only need to perform CSMA before transmitting –Less than 15ms of latency –Highly efficient use of battery power ZigBee offers longer battery life and lower latency than a Bluetooth equivalent.

36. Month Year Copyright 2003 The ZigBee Alliance, Inc. 36 ZigBee and Bluetooth-- Conclusion Protocols are substantially different and designed for different purposes ZigBee designed for low to very low duty cycle static and dynamic environments with many active nodes Bluetooth designed for high QoS, variety of duty cycles, moderate data rates in networks with limited active nodes
