What is Zigbee? this presentation is based on Zigbee this presentation contains what is zigbee how it works what are their types for what is used how it works introducton contains all the things along with the diagram of zigbee this presentation is very easily understandable.. zigbee architectture is involved the application of zigbee the advantages of zigbee the conclusion of zigbee it is very helpful for the projects based on home automation security purposes industrial automation... so go through it contains all details about zigbee

1. Introduction to Zigbee
Waqar Ahmad 7th Semester
Department of Electrical Engineering UET Peshawar, Jalozai Campus

2. Introduction
 In this present communication world there are numerous high data rate
communication standards that are available but non of these meets the
sensor and the control devices communication standards.
 These high data rate communication standard require
 Low latency
 Low energy consumption even at lower bandwidth

3. What is zigbee technology?
 Zigbee communication is specially built for control and sensor networks on
IEEE 802.15.4 for wireless personal Area networks
 Operates on 2.4 GHz frequencies.
 Data rate is 250 kbps.
 Two way transmission of data b/w sensors and controllers
 Range is 10-100 meters

4. Zigbee Architecture

5. Zigbee Architecture
 Zigbee Coordinator:
 Reponsible for handling and storing information
 Receiving and transmitting operation are to be done.

6. Zigbee Architecture
 Zigbee Router:
 Permits data to pass to other devices
 Zigbee End Devices:
 End devices have limited functionality to communicate with parents nodes

7. Zigbee Modes
 There are 2 modes of zigbee
1. Non Beacon Mode
2. Beacon Mode

8. Zigbee Modes
 Non Beacon Mode:
 The coordinator and routers continuously monitor at this state of incoming
data hence more power is consumed
 In this mode router and coordinator do not sleep because any time any node
can wake up and communicate

9. Zigbee Modes
 Beacon Mode:
 When there is no data communication from end devices the router and
coordinator enters to sleep state.
 This mode works for time slot
 They operate when communication is needed.

10. Zigbee Topologies
 Zigbee works on
1. Star topology
2. Mesh topology
3. Cluster topology

11. Advantages
 Low Power Consumption ( Because of active and sleep state ).
 High density of nodes per network ( consist of many nodes so the entire
network should not damage due to some nodes ).
 Low cost ( hence can be implemented in many application).
 Low data rate (upto 250 kbps ).
 Simple implementation ( it can be implemented anywhere).

12. Applications
 Home automation
 Medical data collection
 Traffic monitoring
 Industrial automation

13. Conclusion
 In future, all devices and there controls will be based on standards
 Since it is not only applicable to household devices but aslso to office
automation,
