3. Introduction
Wireless technologies is already an integral part
of our lives.
Bluetooth provides connectivity in a short range of
devices.
WiFi is used for local area networks, thus it is
consumes high power.
WiMAX provides wide area networking, thus it
needs more power and high cost.
But we need in our homes technology that
consumes low power and low cost and low data rate.

6. It is a Technological Standard created for
Control and Sensor Networks
Based on the IEEE 802.15.4 Standard
Designed for low-power and low-data rate
applications.
Like:
Monitoring applications.
Control applications.
Switching applications. 6
7. ZigBee networks has a capacity of connecting more
than 65,000 devices through different networking
topologies.
The data travel through this range from 20Kbps up to
250 Kbps.
ZigBee network covers a wide range from 10-40m.
Operates in Unlicensed Bands
2.4 GHz band is used worldwide.
868 MHz band is used in Europe.
915 MHz band used in North American.

13. ZigBee Coordinator (ZC)
– One required for each ZB network.
– Initiates network formation.
ZigBee Router (ZR)
– Participates in multihop routing of
messages.
ZigBee End Device (ZED)
– Does not allow association or routing.
– Enables very low cost solutions

14. ZigBee’s Network layer supports three networking
topologies: star, mesh, and cluster tree.

16. - Used in home for the following applications :
Light switches and lights .
HVAC (Heating, Ventilating, and Air
Conditioning) controls and thermostats .
Computers, TVs, and other electronic devices .
Smoke detectors and other safety equipment .
Alarm panels, motion sensors, and other security
devices .
Electricity, water, and gas meters.

19. • Network Scan
Device scans the 16 channels to determine the best channel
to occupy.
• Creating/Joining a PAN
Device can create a network (coordinator) on a free channel or
join an existing network
• Device Discovery
Device queries the network to discover the identity of devices
on active channels
• Service Discovery
Device scans for supported services on devices within the
network
• Binding Devices communicate via command/control messaging

21. The name ZigBee is said
to come from the honey bee
which uses a zig-zag type
of dance to communicate
important information to
other hive members.

22. ZigBee is a technological standard created for control
and sensor networks .
Based on the IEEE 802.15.4 Standard
Designed for low-power and low-data rate applications
ZigBee has a wide applications in heath and
environment and homes and telecom
Management of lighting, heating and cooling systems
from anywhere in the home.
ZigBee has many advantages as it is easy to deploy,
consumes low power, its cost is very low and it is very
secure.
