Zigbee ppt
- 1. welcome
- 3. The ZigBee NameNamed for erratic, zig-zagging patterns of bees between flowersSymbolizes communication between nodes in a mesh networkNetwork 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. introductionZigbee 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 2005Much research is still going on with ZigBee.
