  • 1. welcome
  • 2.
  • 3. The ZigBee Name
    Named for erratic, zig-zagging patterns of bees between flowers
    Symbolizes communication between nodes in a mesh network
    Network components analogous to queen bee, drones, worker bees
  • 4. What is ZigBee?
    Technological Standard Created for Control and Sensor Networks
    Based on the IEEE 802.15.4 Standard
    Created by the ZigBee Alliance
  • 5. introduction
    Zigbee is specification for high level communication protocols using small.
    The IEEE 802.15.4 standard was completed in May 2003.
    The ZigBee specifications were ratified on 14 December 2004.
    The ZigBee Alliance announced public availability of Specification 1.0 on 13 June 2005
    Much research is still going on with ZigBee.
  • 6. ZigBee uses
    It is used for embedded application for low data rates and Low power consumption, In expensive
    Small packet networks
    Home Entertainment and Control
    Wireless sensor network’s
