  3. 3. What is Bluetooth  Bluetooth is the technology that connect and transmit voice and data to mobile phones, computers and other devices without the use of wires.  Bluetooth makes wireless communication and networking between devices in a small localized area that ranges from 1metres to 10metres.  Bluetooth technology eliminates the need for numerous and inconvenient cable attachments.  It is the standard of IEEE 802.15.1.1/10/2013
  4. 4. Origin Of Bluetooth Bluetooth mainly came into being as a solution to the cumbersome problem of cables and it was conceived as a cable replacement technology. It was mainly built for providing a short-range wireless solution to the consumer.
  5. 5. Why The Name Bluetooth Have you ever imagined how the name Bluetooth relates to the technology ? Interesting story. In 1994 Bluetooth was developed by Ericsson which is a Danish company. They named it after a Danish king, whose nickname was Bluetooth because he brought the Danish tribes together.
  6. 6. How Bluetooth Works? Bluetooth uses something called frequency-hopping spread spectrum, which is a radio technology. Frequency-hopping spread spectrum (FHSS) is a technique of transmitting radio signals by hopping or changing a carrier among many frequency channels, using some sequence which is known to both transmitter and receiver.1/10/2013
  7. 7. Bluetooth uses a networks topology called a Piconet . When a piconet is formed between two or more devices, one device takes the role of master, and all other devices assume a slave. Piconets contain a minimum of two and a maximum of eight Bluetooth devices.1/10/2013 PICONET STRUCTURE
  8. 8. It is like establishing a master-slave relationship. The Bluetooth devices can function both as a master and a slave. Piconet is nothing but a network on master and one or more slaves. Each Piconet is defined by a different channel to which the user synchronizes. Each of these Piconets has a maximum capacity. All the devices in the Piconet hop together. The Piconets communicates with each other and thus form a network structure which is called Scatternet. A Scatternet is a number of interconnected piconets that supports communication between more than 8 devices.1/10/2013
  9. 9. SCATTERNET STRUCTURE1/10/2013 Cross-Piconet communication
  10. 10. Bluetooth supports the following kind of broadcasts between thedevices in a Piconet. 1. Wireless point-to-point 2. Wireless point-to-multipoint

  12. 12.  A company called Beam is introducing a Bluetooth-enabled toothbrush. It came to the market in March 2012. The Beam toothbrush will available for purchase in November. The Beam Toothbrush is a technologically advanced toothbrush equipped with Bluetooth capability and an accompanying smartphone app. Its main job is to monitor a persons dental hygiene using sensors that sync with an app, which will then track that data and offer incentives to improve their brushing habits. Sensors in the Beam Brush are activated by contact with the mouth, which syncs with a timer in the app to time how long a user actually spends brushing their teeth. The app will also track this over a period of time, so people can share the results with their dentist and see if1/10/2013 they need to improve their habits.
  13. 13. It will also detect how long a person scrubs different areas of their mouth aswell, and play music while they brush. Beam Technologies is also planningto add some social elements and game-like achievements to reward usersfor their good dental habits. It should be a useful tool in particular for parentswho want to make sure their children are brushing their teeth correctly.
  14. 14. Advantage Of Bluetooth WirelessBluetooth works with out cable, it works with wireless. Low energy consumption Bluetooth uses low power signals. for that reason technology need littleenergy, and will use less battery.Bluetooth Technology is inexpensive Bluetooth is cheap to manufacture, and anyone can buy it.Sharing voice and data The Bluetooth allows to devices to share voice and data communications.1/10/2013
  15. 15. Disadvantage Of BluetoothData Transfer RateBluetooth has a low data rate( i.e.1 MBps) in comparision to infra-red(i.e.4 MBps).RangeBluetooth only has a range of 15 to 30 feet depending on the device.The small range is a disadvantage for some who may want to use aBluetooth device outside of that 30-foot radius.1/10/2013
  16. 16. When there are a number of mobile devices in the same room, and possibly attempting the same operation. Since Bluetooth is omni-directional, it encounters problems in discovering the intended recipient device.1/10/2013
  17. 17. Application of Bluetooth Connect your wireless headset to your mobile phone, mobile computer or any wired connection to keep your hands free for more important tasks when youre at the office or in your car.  By installing a Bluetooth network in office you can do away with the complex task of networking between the computing devices. Each Bluetooth device could be connected to 200 other devices. It supports both point to point and point to multipoint connections. The Bluetooth technology connects all your peripherals wirelessly. Connect your pc or to printers , scanners and other devices without the trouble of cable attachments.1/10/2013
  18. 18. ConclusionIn conclusion, Bluetooth is a wireless technology thatwill make connections between variousdevices. Bluetooth Technology takes away the needfor several problematic cable attachments forconnecting mobile phones, handheld devices, andcomputers. It is easy, simple, and inexpensive. Thenext time you think wireless, think Bluetooth...its thebest way to communicate!
