3.  INTRODUCTION
 A Zig Bee is a wireless applications, standard has been developed by the IEEE.
 Zigbee is the most popular industry wireless mesh networking standard for linking sensors,
instrumentation and control systems.
 Zigbee is a global, open, packet-based protocol designed to offer an easy-to-use architecture for a
reliable, safe, low power wireless networks.
 There are many wireless monitoring and control applications for industrial and home
markets which require longer battery life, lower data rates and less complexity than available
from existing wireless standards.

4.  OBJECTIVES
 Low data rate
 Low power consumption
 It is an small packet devices
 Supports large number of nodes.
 It covers 10-100 meters range.

6.  How Zig Bee Works ?
Topology like :
• Star
• Cluster Tree
• Mesh
Network coordinator, routers, end devices

7.  Layers of zigbee network
Network and Application Support layer.
Physical (PHY) layer.
Media access control (MAC) layer.

8.  Block Diagram

9.  Advantages
 It serves wireless communication standard and a collection of protocols
for interconnecting smart devices, sensors, embedded systems, and
other technologies such as real-time analytics, object tracking and
locating, and machine learning.Low duty cycle – provides long battery
life.
 Ability to manage home appliance network remotely.
 The Zigbee technology has a flexible structure. It has an easy
installation process and also has long battery
 Zigbee technology is easy to control and monitor with the help of a
remote.

10.  Limitations
 It is not secure like wifi based secured system.
 Replacement cost will be high when any problem occurs in zigbee
compliant home appliances.
 It requires knowledge of the system for the owner to operate zigbee
compliant devices.

11.  Application
 Home Automation
 Wireless sensor networks.
 Industrial control systems.
 Embedded sensing.
 Medical data collection.
 Smoke and intruder warning.
 Building automation.
 Remote wireless microphone configuration.

12. Conclusion & Future Scope
 Since there are no global standards so far in wireless sensor networks,
the ZigBee plays vital role in most of the wireless application.
 In most industries it is observed, there is an increasing demand of ZigBee
based wireless applications.
 Zig bee is the neweast and provides specifications for devices that have
low rates,consume very low power and characterized by long battery
life.
