What is Bluetooth?• Short-range communications technology• 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, low power, and cost
Why Bluetooth?• Expansive growth in the last few years
• Recent driving laws will cause an increased need for Bluetooth technology, and we would like everyone to know what it exactly is
• It is the future of communication, as the amount of Bluetooth application possibilities is endless
How does Bluetooth work?• When device is put in discoverable mode, each device only knows about
itself.• INQUIRY identifies who else is in the range• PAGING creates a link between a device• EXPANDING creates link between following devices
Advantages vs. DisadvantagesAdvantages 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
Applications of Bluetooth
• Telephones• Headsets• Computers• Computer accessories• LAN peripherals• Multimedia Devices
Human Impact• Common concern is that carrier waves inhabit the same band
as that of microwave ovens• Transmitting power is much too weak to affect humans• Exposure to Bluetooth radio frequencies does not result in
heating of the body• This is where the future development for Bluetooth will head,
in making sure this form of communication is safe.
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
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
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
DEVICE TYPES
–Zigbee Coordinator
–Zigbee Router

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………
