This presentation introduces Bluetooth technology. It is comprised of four group members and discusses Bluetooth's features such as short-range wireless communication, security, and growth. The presentation also covers Bluetooth applications, how devices connect and communicate via Bluetooth, advantages and disadvantages, and examples of Bluetooth-enabled devices. Zigbee technology is then introduced as a standard for low data rate wireless devices with long battery life that is well-suited for home and building automation.

• Intended to replace cables connecting portable and/or
fixed devices
• Still able to maintain a high level of security
• Defines uniform structure for wide range of devices
to connect and communicate
• Key features are
– Robustness,lowpower,andcost

7. Advantages Disadvantages
• Offers a great deal of possibilities • Data rate of only 1 MBps.
• Freedom from cables • Open to interception and attack
• Accuracy in Local Area Networks (LAN) • Battery use increased on devices
• Operating range of up to 100 metres • Cannot work in a long distance
environment
• Low power and low processing
• Applications are virtually endless
• Inexpensive
• Does not need to be configured
•Security features of authentication,
authorization, and encryption

10. WHAT IS ZIGBEE
• ZigBee is a new wireless
technology
• Technological Standard Created
for Control and Sensor
Networks
• High level communication
• Frequency band up to 2.4GHz

11. WHY ZIGBEE IS NEEDED
• For Long Battery Lives
• It require low cost and very low current
drain.
• It doesn't need much power
• It uses low data rates

12. ZigBee General Characteristics
• Data rates of 20 kbps and up to
250 kbps
• Support for Low Latency
Devices
• Low Power Usage consumption
• Supports large number of nodes
• High Security
• Low Data Rate
• Very long battery life

13. DEVICE TYPES
–Zigbee Coordinator
–Zigbee Router
–Zigbee End Device

15. Application Sectors
CONSUMER
ELECTRONICS
PC &
PERIPHERALS
HOME
AUTOMATION
TOYS &
GAMES
ZIG BEE
LOW DATA-RATE
RADIO DEVICES
INDUSTRIAL &
COMMERCIAL
PERSONAL
HEALTH CARE

16. Conclusion
In future all devices and their controls will be
based on this standard.
Since Wireless personal Area Networking
applies not only to household devices, but also
to individualized office automation
applications, ZigBee is here to stay. It is more
than likely the basis of future home-
networking solutions………
