- 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.

- 6. BLUETOOTH 6 The world according to Bluetooth:
- 7. Product Association Phone : Music, data. 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.

- 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) HOW BLUETOOTH WIRELESS TECHNOLOGY WORKS Bluetooth

- 14. Personal Area Networking (PAN) THE LAST USAGE MODEL, PERSONAL AREA NETWORKING (PAN), FOCUSES ON THE AD-HOC FORMATION AND BREAKDOWN OF PERSONAL NETWORKS 14
- 15. 8 April, 2011 15 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
- 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
