  3. 3.            What is Bluetooth? History of Bluetooth Versions Network Architecture How it works? Advantages Disadvantages Application Areas Future Scope Conclusion References
  4. 4. Bluetooth is a wireless technology used to transfer data between different electronic devices. The distance of data transmission is small in comparison to other modes of wireless communication. This technology eradicates the use of cords, cables, adapters and permits the electronic devices to communicate wirelessly among each other. The purpose of Bluetooth technology is to connect numerous electronic devices together without the need of wires.
  5. 5. -> The name Bluetooth was inspired by “Herald Bluetooth” was king of Denmark who ruled in 10th century. ->Bluetooth was invented in 1994 by Jaap Haartsen and Sven Mattisson, who were working for Ericsson Mobile Platforms in Sweden. ->Bluetooth is not owned by any company and is developed and maintained by SIG(Special Interest Group). The SIG was formally announced on May 20, 1998. ->The SIG comprises more than 1000 companies. The major companies who created the technology include Intel, Samsung, Ericsson, IBM, Motorola, Nokia, Toshiba
  6. 6.  1998 - Bluetooth technology is officially introduced  1999 - Bluetooth 1.0 Specification is introduced.  2003 - Bluetooth Core Specification with the announcement of Version 2.1.  2004 - Bluetooth Version 2.0 + EDR (Enhanced Data Rate) is introduced.  2005 - Version 2.0 + EDR in late 2005.  2007 - Bluetooth Core Specification Version 2.1 + EDR  2009 - Bluetooth Core Specification Version 3.0 + HS (High Speed) is adopted.
  7. 7. . Piconet 1 Piconet 2 Slave Master Master Scatternet     Piconet = set of eight devices can communicate in a ad – hoc fashion called a piconet. Scatternet = set of piconet Master-Slaves can switch roles(A master can simultaneously connect up to seven slaves.) A node can only be master of one piconet. Adopted protocols TCP/UDP/IP/PPP Wireless Networks Spring 2005
  8. 8. It comprises of a base band processor, a radio and an antenna . The base-band processor converts the data into signals, the antenna of another blue tooth device, within at least 30 feet distance, receives a transmitted signal in the air.       Each frame consists of a transmit packet and a receive packet. Each packet may have either 1, 3 or 5 slots. Single slot packet – max data rate of 172Kbps Multi slot frames support higher rates– 721Kbps or a max. of 3 voice channels. A device can’t be masters for two piconets The slave of one piconet can be the master of another piconet
  9. 9. • Wireless (No Cables) • No Setup Needed • Energy Efficient • • Cheap and Portable Industry Wide Support • Connection is fast and easy • Auto recognition
  10. 10. • •  • • • • Short range 10 meters or 15-30 feet depending upon the device Small throughput rates - Data Rate 1.0 Mbps First time setup can be complicated Slow data transfer rate as compared to Wi-Fi Security is Biggest Disadvantage as transfer takes place through radio waves and a hacker can easily hack it. Limited Bandwidth

  12. 12. • • • Bluetooth, the big improvements added to 3.0 and 4.0 were significant. While the general range of the wireless protocol remains the same (up to 30 feet), version 3.0 enabled a much faster theoretical data throughput of 26Mbps compared with the 2Mbps of version 2.1. The real benefit of Bluetooth 4.0 is energy efficiency. Often, with new technology, early changes mean reconstruction. Not With Bluetooth, instead, there will be an improvement to the existing standard.
  13. 13. Bluetooth wireless technology is optimized for different purposes in different domains WLAN & WPAN, respectively. The same design points that make them well-suited for their primary intended purposes make them less well-suited for other applications. Bluetooth wireless technology is not a robust networking technology; IEEE 802.11 is not the preferred technology for WPAN applications. The IEEE 802 working groups and the Bluetooth SIG have a cooperative relationship, and are working together on the issues of coexistence in the spectrum that they share.
