  3. 3. Definition of Bluetooth.Bluetooth is a short range and low powerwireless technology originally developed forexchanging data over short distances fromfixed and mobile devices, creating personalarea network.
  4. 4. History of Bluetooth The word “Bluetooth” is taken from the 10th century Danish King Harlard, who unified Scandinavian people tribes into a single kingdom. Bluetooth was named because –  Bluetooth technology was developed in Scandinavian.  Bluetooth technology was able to unite different industries such as cell phone, computing and automotive markets. The Bluetooth specification was first developed in 1994 by Ericsson Mobile Communication Ltd.  5 Companies (Ericsson, Nokia, Intel, Toshiba, & IMB) joined to form Bluetooth Special Interest Group (SIG) in 1998.  In 1999, first specification of Bluetooth i.e. Bluetooth 1.0 is released.
  5. 5. Characteristics of Bluetooth Bluetooth stands for Short-range transmission of digital voice and data. Frequency Range: ISM (Industrial, Scientific and Medical Radio Bands) 2200MHz – 2400 MHz Bluetooth used a Radio Technology called Frequency Hopping Spread Spectrum. Vanishes the need of chord and wire. Range of Connection : 10 m – 100 m. Supports data rate of : 1Mb/s.
  6. 6. Characteristics of BluetoothThere are three classes of Bluetooth devices. Class 3 Radio: have range up to 1 meters or 3 feet. Class 2 Radio: most commonly found in mobile devices – have range of 10 metes or 30 feet. Class 1 Radio: used primarily in Industrial use cases – have range of 100 meters or 300 feet.
  7. 7. Working of Bluetooth Uses short range of RF spectrum at 2.45 GHz. Uses quick frequency hoping packet switch Protocol. Transceiver has a unique 48 bit address. Uses IEEE 802 Standards. Several Bluetooth devices can form an AD-HOC Network called a “PICONET”. In PICONET, one device is act like a master (sets frequency hoping behavior) and the others as slaves.
  8. 8. Working of Bluetooth
  9. 9. Working of BluetoothMore than one PICONET is called SCATTERNET.Up to Eight devices are allowed in PICONET.Each PICONET is identified by a different frequency hopping structure.Connections can be made up to 10 meters or can be extended to 100 meters.Power consumption is 0.3 mA.
  10. 10. Security Features of Bluetooth Bluejacking  Funny type message sent to people’s Bluetooth enabled device without owner permission. Bluesnarfing  Hacker’s gaining access to people Bluetooth enabled device mainly to made some harm.  Allows hackers to send message, make phone calls etc.  The hacker to be within 30 ft rage  To avoid set your phone to non-discoverable mode Bluebugging  Advanced level of hacking with technology use  Hacker’s gaining access to people Bluetooth enabled device mainly to made some harm.  Allows hackers to send message, make phone calls etc.  Also 30 ft range
  11. 11. Advantages of BluetoothBluetooth devices are wirelessBluetooth technology is inexpensiveBluetooth is automaticShare voice and dataLow energy consumptionAccessible from anywhere
  12. 12. Disadvantage of BluetoothLow data rate.Short range.Low security.Interference with other devices.
  13. 13. Applications of BluetoothLaptopsCellular phonesPersonal digital assistantsHeadsetsPrintersCarGPS etc…
  14. 14. Future of BluetoothRadio2 Working Group • Working to overcome bandwidth, interference, and connection setup issues while remaining compatible with current radioOther Working Groups • Audio/Video, Car, Co-existence, ISDN, Local Positioning, Personal Area Networking, PrintingStudy Groups • Industrial Automation
  15. 15. ConclusionA new global standard for data and voice Eliminates Cables . Low Power, Low range, Low Cost network devices. Bluetooth seems to have a bright future after reviewing its benefits and wide use. Further improvements are planned to be made in – Data Rates – Power Reduction – Range
