` Introduction

` Working Of Zig Bee

` Zigbee Architecture

` ZiGbee Vs Other Wireless Technology

` Advantages Of Zigbee Technology

` Applications Of Zigbee

` Conclusion



` Technological Standard Created for Control and

Sensor Networks

` Created by zig bee alliance

` Based on the IEEE 802.15.4 Standard

` The technology allows for devices to communicate

with one another



` Name derived from erratic, zig-zagging patterns of

bees between flowers

` Symbolizes communication between nodes in a meshnetwork

` Network components analogous to queen bee, drones,

worker bees



` Topology

Cluster Tree

Peer to peer

Combined

Mesh

Network coordinator, routers,end devices



` Modes of operation Beacon

Non-beacon

`Devices

` Low data rate

`

Low power consumption` Small packet devices

` Larger band width

` networks can support a larger number of

devices and a longer range between devices



` Designed for wireless controls and sensors

`

Operates in Personal Area Networks (PAN¶

s)and device-to-device networks

` Connectivity between small packet devices

` Control of lights, switches, thermostats,appliances, etc.



` Environmental Monitoring

` Agricultural Monitoring

` Home Automation Still on Horizon

` Road map products-tracking

` Consumer electronics

` PC

` Personal and healthcare

` Commercial and residential control



` Zigbee has been developed to meet the growing

demand for capable wireless networking between low-

power devices.

` Zigbee demands low data rate appllications, robust

security, high data reliability.
