  1. 1. By: Raginee Ranjan Sinha Roll: 06ESBEC071 BLUETOOTH
  2. 2. Definition <ul><li>Bluetooth is a method for data communication that uses short-range radio links to replace cables between computers and their connected units. </li></ul>
  3. 3. TABLE:SPECIFICATION OF BLUETOOTH <ul><li>PARAMETER RADIO SPECIFICATION </li></ul><ul><li>Topology Connect up to 8 nodes in logical star(Pico net) </li></ul><ul><li>Frequency Band 2.4-2.4835 GHz, ISM Band </li></ul><ul><li>Channel Bandwidth 1 MHz </li></ul><ul><li>Numbers of Channels 79 </li></ul><ul><li>Peak Data Rate 1 Mbps </li></ul><ul><li>Modulation Technique GFSK </li></ul><ul><li>Transmit Power 0.1 Watt </li></ul><ul><li>Frequency Hop Rate 1600 hops/sec </li></ul><ul><li>Pico net Access FH-TDD </li></ul><ul><li>Scatter net Access FH-CDMA </li></ul>
  4. 4. ORIGINATION OF “BLUETOOTH” <ul><li>In 10 th century Harald Bluetooth the king of Denmark united Norway and Denmark into a single kingdom. Apparently he got that name from his penchant for blueberries. </li></ul>
  5. 5. HISTORY OF BLUETOOTH <ul><li>In 1994, Ericsson Mobile Communication Ltd. Started project named “Bluetooth”. </li></ul><ul><li>In 1998, Bluetooth SIG was formed and it officially adopts the project name “Bluetooth” as the name of technology. </li></ul><ul><li>Frequency Hopping </li></ul><ul><li>Spread Spectrum Technology was used for data transformation . </li></ul>
  6. 6. <ul><li>In 1999, Bluetooth 1.0 & Bluetooth 1.0B Specification was released </li></ul><ul><li>In 2000, Bluetooth headset and phone adaptor from Ericsson; the first consumer product. </li></ul><ul><li>In 2003, Bluetooth 1.2 was released. </li></ul><ul><li>Improved resistance to radio frequency </li></ul><ul><li>interference. Ratified as IEEE 802.15.1-2005 </li></ul>
  7. 7. <ul><li>In 2004, Bluetooth 2.0 with enhanced data rate (EDR) is released. </li></ul><ul><li>In Jun 2007, Nokia and Bluetooth SIG announced that Wibree will be a part of Bluetooth Specification as an ultra low power Bluetooth technology. </li></ul>
  8. 8. <ul><li>In July 2007, Bluetooth 2.1 Core Specification is released. </li></ul><ul><ul><li>Extended Inquiry Response. </li></ul></ul><ul><ul><li>Sniff Sub-rating. </li></ul></ul><ul><ul><li>Secure Simple Pairing. </li></ul></ul><ul><ul><li>Near field Communication (NFC) Cooperation . </li></ul></ul>
  9. 9. Comparison with other wireless technologies <ul><li>802.11 </li></ul><ul><li>Has higher bit rate compared to Bluetooth . But has higher power consumption. Basic a LAN technology so not a direct competitor for Bluetooth </li></ul><ul><li>IrDA (Infrared Data Association) </li></ul><ul><li>Low cost but require Line of sight. Only point to point </li></ul><ul><li>Home RF </li></ul><ul><li>Competing technology. But current Bluetooth is better positioned in market </li></ul>
  10. 10. NEED FOR BLUETOOTH <ul><li>A Cable Replacement Technology </li></ul><ul><li>It’s wireless. </li></ul><ul><li>It’s inexpensive. </li></ul><ul><li>You don’t have to think about it. </li></ul>
  11. 12. Connection via bluetooth
  12. 13. APPLICATION EXAMPLES: <ul><li>A Bluetooth–mouse </li></ul><ul><li>A Bluetooth-keyboard </li></ul><ul><li>Cable-less connection to printers </li></ul><ul><li>Use e-mail while your portable PC is still in the briefcase! </li></ul>
  13. 14. BLUETOOTH DEFINITIONS <ul><li>Single-slave </li></ul><ul><li>Multi-slave (up to 7 “slaves”on one master) </li></ul><ul><li>Scatternet </li></ul>
  14. 15. PICONETS <ul><li>A set of BLUETOOTH devices sharing a common channel is called a PICONET </li></ul>
  15. 16. SCATTERNETS <ul><li>Scatternets are two or more independent and non-synchronized piconets that communicate with each other by making bridge nodes . </li></ul>
  17. 18. COMPONENTS OF ARCHITECTURE <ul><li>Radio Front End (RF) </li></ul><ul><ul><ul><li>Defines characteristics of RF, frequency bands, channel arrangements & receiver sensitivity level. </li></ul></ul></ul><ul><li>Logical Link Control & Adaptation Protocol (L2CAP) </li></ul><ul><ul><ul><li>For transporting bigger data products to higher layer. </li></ul></ul></ul><ul><li>Service Discovery Protocol (SDP) </li></ul><ul><ul><ul><li>T o query and discover services supported by peer Bluetooth devices. </li></ul></ul></ul>
  18. 19. <ul><li>Link Manager Protocol (LMP) </li></ul><ul><ul><li>PICONET, master slave role assignments and link configuration. </li></ul></ul><ul><ul><li>Security configuration by device authentication using secret key. </li></ul></ul><ul><li>RFCOMM </li></ul><ul><ul><li>Provides transport capabilities for high level services. </li></ul></ul>
  19. 20. CREATION OF A SCATTERNET <ul><li>A Master or </li></ul><ul><li>Slave can become </li></ul><ul><li>Slave in another </li></ul><ul><li>piconet by being </li></ul><ul><li>paged by the </li></ul><ul><li>Master in this </li></ul><ul><li>other piconet. </li></ul>
  21. 22. ADVANTAGES OF BLUETOOTH <ul><li>Bluetooth is used widely across countries and almost by everyone. </li></ul><ul><li>It has simple features. </li></ul><ul><li>It is free of charge and not added to our budget. </li></ul><ul><li>It allow us to stay cord free. </li></ul><ul><li>It has the ability to keep our information private. </li></ul><ul><li>Bluetooth isn't requires a line of sight. </li></ul>
  22. 23. Advantages (contd.) <ul><li>It provides ranges of up to 100 meters. </li></ul><ul><li>Bluetooth is also low power and low processing with an overhead protocol. </li></ul><ul><li>To put it short, the applications with Bluetooth are virtually endless. </li></ul>
  23. 24. DISADVANTAGES OF BLUETOOTH <ul><li>More battery power when Bluetooth is enable on the phone all day. </li></ul><ul><li>Throughout all device, when using Bluetooth internet, the connection sometimes may run very slow so Bluetooth internet is not highly suggested for all cases. </li></ul><ul><li>The only real downside s are the data rate and security. Infrared can have data rates of up to 4 M Bps, which provides very fast rates for data transfer, while Bluetooth only offers 1 M Bps </li></ul>
  24. 25. CONCLUSION <ul><li>Bluetooth is a short range radio link wireless technology used to connect various device by a invisible link getting rid of wires. </li></ul><ul><li>Last but not the least, WHENEVER THINK OF WIRELESS,”THINK BLUETOOTH”, this is the best way of communication. </li></ul>
  25. 26. BIBLIOGRAPHY <ul><li>WIKIPEDIA </li></ul><ul><li> </li></ul><ul><li>E-book on Wireless Lan Techniques-RF, Wi-Fi, Bluetooth. </li></ul><ul><li>E-book on Introduction of Bluetooth. </li></ul><ul><li>Wireless Technology By-INTEL. </li></ul><ul><li>E-book on Bluetooth Security. </li></ul>
