  3. 3. Introduction • What is Bluetooth? • Why is it useful? • Governing Standard-Large Consortium
  4. 4. What is Bluetooth technology • Bluetooth is a wireless technology used to transfer data between different electronic device the distance of data transmission is small in comparison to other modes of wireless communication. • Bluetooth is a high –speed low-power link microwave wireless technology designed to connect phones,laptops,pdas and other portable equipment together with tittle or no work by the users.
  5. 5. Importance of Bluetooth • These have replace cables for transfering information from one electronic device to another one. • This is cheaply Available. • Its mobility is also very important as it does not need any power outlet or Internet connection or any other items.
  6. 6. Types of Bluetooth devices • (1)Headset. • In car Bluetooth system. • Bluetooth Equipment printer. • Bluetooth Equipment web cam. • Bluetooth GPS system. • Bluetooth keyboard. • Bluetooth wireless mouse.
  7. 7. How it work • Short range wireless connectivity. • Low power consumption. • Automatic recognition. • Privacy/Security. • Very important. • Don’t want data to be shared. • Security not great. • Pairing security.
  8. 8. How to connects • Once the device is turned on it sends out a signal searching for other devices. • It operates on the unlicensed industrial Scientific and medical(JSM) radio band. • Once a connection is mode a personal area network is formed the signal uses Adaptive frequency Hopping (ADF) to “hop” along 79 frequencies about 1600 times. • The Range of these devices is divided into 3 classes .1st 100mw 100 meters 2nd 2.5mw 10 meters 3rd 1mw 1 meters.
  9. 9. Reliability • What is really means? • Which device are you connecting to? • How large it the file ? • Which version are you using? • Have the two devices been connected before. • Devices • Laptop ,Gaming console,Headsets,Cellphone,Printer.
  10. 10. Disadvantage of Bluetooth □Data sent between two Bluetooth devices is very slow compared with Wi-Fi transfer rate. □Range of Bluetooth devices is 15-30 feet depending upon the device. □Security is biggest disadvantage as transfer take place through radio waves and a hacker can easily hack it.
