This document provides an overview of Bluetooth technology, including its history, how it works, applications, advantages, and future. Bluetooth was created in 1994 by engineers seeking to develop a short-range wireless standard. It was named after the 10th century Danish king Harald Bluetooth, who united Denmark and Norway. Bluetooth allows devices to connect ad-hoc within a piconet of up to 7 devices or across multiple piconets in a scatternet. Common applications include connecting headphones, keyboards, and transferring contacts between phones and cars. The technology continues to improve security and capabilities with new versions.

- 3. Bluetooth is a wireless technology that is mainly used for transfer data between different electronic devices for ad-hoc wireless communication of voice and data anywhere in the world.
- 4. Cable Replacement Low Cost Low Power Small Size
- 5. Overview of Bluetooth History Why this name? 1.It was taken from the 10th century Danish King Harald Bluetooth(940-981) who was famous for uniting Denmark and Norway into a single nation. 2. He was also successful in converting all the Danes to Christianity.
- 6. When does it appear? 1. In 1994, Jim Kardach, an Intel engineer working on wireless technologies. Kardach took on the role of a cross-corporate mediator dedicated to bringing various companies together to develop an industry-wide standard for low-power, short-range radio connectivity. 2. Together with 4 other companies (IBM, INTEL, TOSHIBA, NOKIA) it formed a SIG. (Special Interest Group) 3. The project is named as Bluetooth.
- 7. Words of Kardach after uniting all the companies: Bluetooth was borrowed from the 10th-century, second king of Denmark, King Harald Bluetooth; who was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link.
- 8. Definition Two or more Bluetooth units sharing the same channel One device acts as a master and the devices connected to it act as slaves. Slaves can not directly send data to each other. In effect, the master acts as a switch for the piconet and all traffic must pass through the master. There can be up to 7 active slaves in a piconet but only one master.
- 10. DEFINITION A set of two or more interconnected piconets form scatternets. A Bluetooth unit can be a slave in two or more piconets, but it can be a master in only one. Devices that participate in two or more piconets may act as gateways. Bluetooth units can only transmit and receive data in one piconet at a time. Piconets may be identified by the master's identity and clock. Devices give notification of inactivation to master before becoming inactive in its piconet for a finite length of time.

- 17. Characteristics of Bluetooth Bluetooth stands for Short-range transmission of digital voice and data. Bluetooth used a Radio Technology called Frequency Hopping Spread Spectrum. Frequency Range: 2200MHz 2400 MHz Vanishes the need of chord and wire. Range of Connection : 10 m 100 m. Supports data rate of : 1Mb/s.
- 18. Classes 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.
- 19. Applications of Bluetooth Laptops Cellular phones Personal digital assistants Headsets Cable less connections to Printers Bluetooth Mouses Bluetooth Keyboards GPS etc
- 21. Eliminates wires Facilitates Data and Voice Communication Offers formation of Ad hoc networks Standardized protocol Free of charge Easy to use Low power and consumes less battery Stationary and mobile environments
- 22. Relatively short range Less secure Interference with other devices Mediocre Data rates Bluetooth internet connection gets slow sometimes More battery power when Bluetooth is enable on the phone all day
- 24. Future Of Bluetooth Bluetooth has a good future ahead because it meets a basic need of connectivity. Latest version of Bluetooth are improving both its security and capabilities. New versions of Bluetooth technology will meet the high-speed and large range. Many companies are designing impressive Bluetooth applications in demand.
- 25. CONCLUSION Bluetooth is a short range radio link wireless technology used to connect various device by a invisible link getting rid of wires. Bluetooth seems to have a bright future after reviewing its benefits and wide use.
