  1. 1. BY:CH.Lakshmi ramSoumyajit dhal
  2. 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. 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 interoperate3
  4. 4. WHY ZIGBEE? • Reliable • Mesh networking • Low data-rate applications • Very long battery life • Secure • Scalable • Low cost • Global applicability4
  5. 5. ZIGBEE IS FROM?• 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. 6. TARGET MARKETS  TV  Monitors  VCR  Sensor Consumer  DVD Industrial & s Electronics  Automation Commercial  CD  Control  Remote PC Peripherals  Mouse Low Data Rate Personal  Keyboard Radio Devices Healthcare  Joystick  Gamepad  Monitors  Diagnostic  s Sensor Home  Security Toys &  PETs  HVAC s  Gameboy Automation Games  Lighting  s Educationa  Closure l s
  7. 7. PC And Peripherals • Desktop PCs and Home Entertainment Systems (Home Theatre TV) o Computer peripherals; o HID devices • Video conference equipment o Remote control • Video gaming equipment o Multi-player PC & video games o Remote controls for audio and video equipment7 7
  8. 8. Human Input Devices (HID) • Keyboard • Mouse / Pointing Device • Remote Controls (controls for audio & video equipment) • Gaming device • Double Joystick88
  9. 9. PATIENT MONITORING • May allow more patient freedom o Monitors vital statistics and sends via graphic internet  Patient can remain in their own home  Lowers cost and improves comfort o Can be used in hospice care  Patients are allowed greater movement  Reduced staff to patient ratio  Light way to bathroom when they get graphic out of bed  Reduces patient confusion1010
  10. 10. LIGHTING CONTROL • Wireless Lighting Control o Dimmable ballasts o Light switches anywhere o Customizable lighting schemes o Energy Saving on bright days12
  11. 11. ZIGBEE VSBLUETOOTH
  12. 12. ZIGBEE AND BLUETOOTH Optimized for different applications • ZigBee • Bluetooth o Smaller packets over large o Larger packets over small network network o Ad-hoc networks o Mostly Static networks with o File transfer many, infrequently used o Screen graphics, pictures, hands- devices free audio, Mobile phones, o Home automation, toys, headsets, PDAs, etc. remote controls, etc.17
  13. 13. WIRELESS TECHNOLOGY COMPARISONCHARTStandard Bandwidth Protocol Stack Stronghold Applications SizeZigBee 250kbps 4-32KB Long battery life, Remote control, low cost battery-operated products, sensorsBluetooth 1 Mbps ~100+KB Interoperability, Wireless USB, cable handset, headset replacementWi-Fi Up to 54Mbps 100+KB High data range Internet browsing, PC networking, file transfers
  14. 14. ZIGBEE AND BLUETOOTH Address Different Needs • Bluetooth is a cable replacement for items like Phones, Laptop Computers, Headsets • Bluetooth expects regular charging o Target is to use <10% of host power19
  15. 15. ZIGBEE AND BLUETOOTH Address Different Needs • ZigBee is better for devices Where the battery is ‘rarely’ replaced o Targets are :  Tiny fraction of host power  New opportunities where wireless not yet used20
  16. 16. ZigBee and Bluetooth CONCLUSION • ZigBee targets applications not addressable by Bluetooth or any other wireless standard • ZigBee and Bluetooth complement for a broader solution21
  17. 17. 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 FailureHybrid (Cluster PAN coordinatorTree)• Flexibility Full Function • Reliability/Range of Device Function Reduced Mesh • Battery Life of Star Device24 • Design Complexity

  23. 23. IEEE 802.15.4 • IEEE 802.15.4 is a standard defined by IEEE for low rate, wireless personal area network. • The standard defines the Physical layer and Medium Access Layer30
  24. 24. 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 topologies31
  25. 25. THE ZIGBEE PLATFORM End developer applications, designed using application ZA1 ZA2 … ZAn IA1 IAn profiles Application interface designed API UDP using general profile IP Topology management, MAC management, routing, discovery ZigBee NWK 802.2 LLC protocol, security management MACChannel access, PAN maintenance, reliable data transport IEEE 802.15.4 MAC IEEE 802.15.4 PHY Transmission & reception on the physical radio channel 32
  26. 26. DATA TRANSFER MODEL Coordinator to Device Device to Coordinator Beacon Enabled Mode Non-Beacon Enabled Mode33

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