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.
BluetoothHistoryBegan 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.
Product Association Phone : Music, data.
Laptop : Transfer data ,connect to various gadgets.
Printer : Wireless print data, photos.
Camera : Send images to printer, mobile, pc.
Product Association (Cont’d)
TV : Unique slide show.
Headset : Keep your hands free.
Photo Viewer : Without memory cards.

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.
Bluetooth
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.
Bluetooth: Advantages1. Bluetooth Devices are Wireless
2. Bluetooth Technology is Inexpensive
3. Multiple Product Association.
4. Low Energy Consumption
5. Bluetooth is Automatic.
Bluetooth: Disadvantages1. One device at a Time
2. Low Data Transfer Rate
3. Security Threats
◦ Bluejacking
◦ Bluesnarfing
◦ Bluebugging
Success of Bluetooth depends on how well it is integrated into consumer productsConsumers 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 FactorsInteroperabilityMass Production at Low CostEase of UseEnd User Experience
Future of Bluetooth
