  1. GENERAL PRESENTATION ON BLUETOOTH Neeraj Dhiman

  2. What is Bluetooth?Bluetooth is an inexpensive, short-range, low-power wireless networking technology developed to replace cables and wires. Bluetooth is becoming the standard for wireless communication.

  3. Who Developed Bluetooth? Bluetooth was originally developed by Ericsson, and then in 1998, Bluetooth was formally introduced by IBM, Ericsson, Intel, Nokia and Toshiba. These companies formed a trade association known today as the Bluetooth Special Interest Group (SIG). Thousands more companies have joined and are committed to developing the Bluetooth standard.

  4. Why is it Called Bluetooth? • The name "Bluetooth" is taken from the 10th century Danish King, Harald Bluetooth. King Bluetooth had been influential in uniting Scandinavian Europe during an era when the region was torn apart by wars. The Bluetooth SIG felt the name was fitting, seeing how the technology is designed to allow cooperation between differing industries such as the mobile phone, computing and automotive markets. Bluetooth is a single standard that unites and simplifies multiple forms of communication used by multiple different devices.

  5. VERSIONS OF BLUETOOTH Version Data Rate Version 1.2 1 Mbit/sVersion 2.0 3 Mbit/sWiMedia Alliance 53 - 480 Mbit/s

  6. How Bluetooth Technology Works Connecting Devices Q: Will the devices communicate via wires or through the air? Q: How will messages or information be sent between the two devices? Q: How will they know if they received the same message that was sent?

  7. What is the Range of Bluetooth?

  8. How Secure are Bluetooth Networks? Bluetooth utilizes two types of security measures. First, Bluetooth uses frequency hopping (1600 hops/sec), which is added protection against eavesdropping. Next, there is built-in security at the physical layer. This feature allows one-way, two-way, or no authentication through the use of PINs. Security setup and key management are done by the software layers. This allows the user to set the security requirements as needed. Users are in control of the relationships between Bluetooth devices and networks. For Example: you will be able to allow your roommate's computer to connect to your Bluetooth printer, but you can also prevent him from accessing your MP3 player.

  9. What Kind of Devices Use Bluetooth? • Many devices use Bluetooth technology today. It is commonly used in computers, cell phones, MP3 players, printers, keyboards and mice, GPS receivers, phone and computer headsets, and many more. As Bluetooth technology continues to grow, so will the number of devices that use it.

  10. The Advantages of Bluetooth Main Reasons to Use a Bluetooth Device: • Bluetooth Devices are Wireless. • Bluetooth Technology is Inexpensive. • Bluetooth is Automatic. • Standardized Protocol = Interoperability • Low Interference • Low Energy Consumption • Instant Personal Area Network (PAN) • Upgradeable

  11. Limitations of Bluetooth There are two main limitations of the current Bluetooth wireless standard: • Slow transfer rate • Susceptibility to interference

  12. The future of Bluetooth • Bluetooth 3.0 It's FAST Picture this... High bandwidth mitigates interference Backwards compatibility
