3. BLUETOOTH
What is Bluetooth?
Bluetooth is a wireless, automatic connection
that is aimed at simplifying and communicating
in the internet and data synchronization
facilitating cable replacement technology.
It works on a universal medium to bridge the
data networks, peripheral interfaces to form a
short range digital unlicensed radio frequency
of 2.4GHz in a wide range of 10mts.

4. Bluetooth
History
Began as a private development effort at Ericsson in
1994.
The project became successful in spring 1998, the
companies-ERICSSON,TOSHIBA, INTEL, IBM and
NOKIA founded the Bluetooth consortium with the
goal of development of a single-chip, low cost, radio-
based wireless network technology.
First specification released in July 1999.

Laptop : Transfer data ,connect to various gadgets.
Printer : Wireless print data, photos.
Camera : Send images to printer, mobile, pc.

8. Product Association (Cont’d)
TV : Unique slide show.
Headset : Keep your hands free.
Photo Viewer : Without memory cards.
Gaming : Wireless controllers.

Bwt-enabled Devices Form Network Topologies Called
Piconets And Scatternets.A Piconet Consists Of Up To
Eight Bwt-enabled Devices. A Piconet Consists Of Up To
Eight Bwt-enabled Devices.

10. BWT-enabled devices operate in the unrestricted 2.4-gigahertz (GHz) Industrial,
Science, Medical (ISM) band. The ISM band ranges between 2.400 GHz and 2.483
GHz.
BWT-enabled devices use a technique called frequency hopping to minimize
eavesdropping and interference from other networks that use the ISM band. With
frequency hopping, the data is divided into small pieces called packets. The
transmitter and receiver exchange a data packet at one frequency, and then they
hope to another frequency to exchange another packet. They repeat this process
until all the data is transmitted.
There are three classes of BWT radio devices, each with a different maximum range:
 Class 1 (100 m)
 Class 2 (50 m)
 Class 3 (10 m)

SECURITY
Security Measure
◦ Link Level Encryption & Authentication.
◦ Personal Identification Numbers (PIN) for device
access.
◦ Long encryption keys are used (128 bit keys).
◦ These keys are not transmitted over wireless. Other
parameters are transmitted over wireless which in
combination with certain information known to the
device, can generate the keys.
◦ Further encryption can be done at the application
layer.

16. Bluetooth: Advantages
1. Bluetooth Devices are Wireless
2. Bluetooth Technology is Inexpensive
3. Multiple Product Association.
4. Low Energy Consumption
5. Bluetooth is Automatic.

17. Bluetooth: Disadvantages
1. One device at a Time
2. Low Data Transfer Rate
3. Security Threats
◦ Bluejacking
◦ Bluesnarfing
◦ Bluebugging

18. Bluetooth Is Everywhere

19. Success of Bluetooth depends on how well it is integrated into
consumer products
Consumers are more interested in applications than the technology
Bluetooth must be successfully integrated into consumer products
Must provide benefits for consumer
Must not destroy current product benefits
Key Success Factors
Interoperability
Mass Production at Low Cost
Ease of Use
End User Experience
Future of Bluetooth
