  2. WHAT IS ZIGBEE? • Technological Standard Created for Control and Sensor Networks • Based on the IEEE 802.15.4 Standard • Created by the ZigBee Alliance

  3. SENSOR/CONTROL NETWORK REQUIREMENTS • Large networks (large number of devices and large coverage area) that can form autonomously and that will 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 3

  4. WHY ZIGBEE? • Reliable • Mesh networking • Low data-rate applications • Very long battery life • Secure • Scalable • Low cost • Global applicability 4

  5. HOW DOES ZIGBEE WORK? Engineers feel Wi-Fi and Bluetooth may be unsuitable. This spawned the idea of digital radio networks via direct-sequence spread spectrum coding. ZigBee-compliant radios may operate on one of three different radio bands: the 800 MHz, 900 MHz, or 2.4 GHz frequencies. Follows the internationally recognized radio standard for the MAC and PHY Layer.

  6. TARGET MARKETS  TV  Monitors  VCR Consumer Electronics  Sensors  DVD Industrial & Commercial  Automation  CD  Control  Remote PC Peripherals  Mouse Low Data Rate Radio Devices Personal Healthcare  Keyboard  Joystick Gamepad   Monitors  Diagnostics  Security  Sensors Home Automation  PETs Toys & Games  HVAC  Gameboys  Lighting  Educational  Closures

  7. PC And Peripherals • Desktop PCs and Home Entertainment Systems (Home Theatre TV) • Computer peripherals; • HID devices • Video conference equipment • Remote control • Video gaming equipment • Multi-player PC & video games • Remote controls for audio and video equipment 7 7

  8. Human Input Devices (HID) • Keyboard • Mouse / Pointing Device • Remote Controls (controls for audio & video equipment) • Gaming device • Double Joystick 8 8

  9. PATIENT MONITORING graphic May allow more patient freedom Monitors vital statistics and sends via internet Patient can remain in their own home Lowers cost and improves comfort Can be used in hospice care Patients are allowed greater movement Reduced staff to patient ratio Light way to bathroom when they get out of bed Reduces patient confusion graphic 1010

  10. LIGHTING CONTROL Wireless Lighting Control Dimmable ballasts Light switches anywhere Customizable lighting schemes Energy Saving on bright days 12

  11. ZIGBEE VS BLUETOOTH

  12. ZIGBEE AND BLUETOOTH Optimized for different applications • Bluetooth • Larger packets over small network • Ad-hoc networks • File transfer • Screen graphics, pictures, hands-free audio, Mobile phones, headsets, PDAs, etc. ZigBee Smaller packets over large network Mostly Static networks with many, infrequently used devices Home automation, toys, remote controls, etc. 17

  13. ZIGBEE AND BLUETOOTH Address Different Needs Bluetooth is a cable replacement for items like Phones, Laptop Computers, Headsets Bluetooth expects regular charging Target is to use <10% of host power 19

  14. ZIGBEE AND BLUETOOTH Address Different Needs ZigBee is better for devices Where the battery is ‘rarely’ replaced Targets are : Tiny fraction of host power New opportunities where wireless not yet used 20

  15. ZigBee and Bluetooth CONCLUSION ZigBee targets applications not addressable by Bluetooth or any other wireless standard ZigBee and Bluetooth complement for a broader solution 21

  16. TOPOLOGY MODELS • Allows users to balance system cost, reliability & battery life Mesh • Reliability • Extended Range • No Battery Life • Routing Complexity Star • Simplicity • Low Cost • Long Battery Life • Single Point of Failure Hybrid (Cluster Tree) PAN coordinator Full Function Device • Flexibility • Reliability/Range of Mesh • Battery Life of Star • Design Complexity Reduced Function Device 24

  22. IEEE 802.15.4 • IEEE 802.15.4 is a standard defined by IEEE for low rate, wireless personal area network. • The standard defines thePhysical layer andMedium Access Layer 30

  23. IEEE 802.15.4 CONTINUED • PHY- It defines low power spread spectrum radio operating at 2.4 GHz with a basic data rate of 250 kbps • MAC -defines how multiple 802.15.4 radios operating in the same area will share the airwaves. The MAC supports several architectures, including a star topology, tree topologies and mesh topologies 31

  24. THE ZIGBEE PLATFORM End developer applications, designed using application profiles ZA1 ZA2 … ZAn IA1 IAn Application interface designed using general profile API UDP IP Topology management, MAC management, routing, discovery protocol, security management ZigBee NWK 802.2 LLC MAC Channel access, PAN maintenance, reliable data transport IEEE 802.15.4 MAC IEEE 802.15.4 PHY Transmission & reception on the physical radio channel 32

  25. DATA TRANSFER MODEL Coordinator to Device Device to Coordinator Beacon Enabled Mode Non-Beacon Enabled Mode 33

  26. THE 802 WIRELESS SPACE WWAN IEEE 802.22 IEEE 802.20 WMAN WiMax IEEE 802.16 Range WLAN WiFi 802.11 ZigBee 802.15.4 802.15.3 802.15.3a 802.15.3c Bluetooth 802.15.1 WPAN 0.01 0.1 1 10 100 1000 Data Rate (Mbps)

  27. PROS AND CONS • Cons • Not many end devices available yet • Single point of failure (centralized architecture) Pros good extension of existing standards supported by many companies low power consumption low cost easy implemented (Designer concentrates on end application) flexible network structure
