Bluetooth technology
- 3. Bluetooth is a radio frequency specification for short range, point to point and to multi point voice and data transfer. In spite of facilitating the replacement of cables, Bluetooth technology work as an universal medium to bridge the existing data networks, a peripheral interface for existing devices and provide a mechanism to form short ad hok network of connected devices away fro fixed network infrastructure
- 4. Why it's name is Bluetooth
- 5. In keeping its namesake, Bluetooth, the new low cost radio technology, is designed to unite or connect all different types of devices to effectively work as one.
- 6. How Bluetooth technology work?
- 7. Bluetooth wireless technology is designed to be as secure as a wire with up to 128 – bit public/ private key authentication, and streaming cipher up to64 bit based on a5 security .
- 8. Transmission types and rates : The baseband (single channel per line)protocols combines circuit and packet switching. To assure that packets do not arrive out of order, slots (up to five) can be reserved synchronous packet. Circuit switching can be either asynchronous or synchronous. Up to three synchronous and one asynchronous data channel, can be supported on one channel. Each synchronous channel support 64Kbs transfer rate which is fully adequate for voice transmissions. An asynchronous channel can transmit as much as 721KBs in one direction and 57.6Kbs in the opposite direction .It is also possible for an asynchronous connection to support 432.6Kbs in both direction if the link is symmetric.

- 12. Security provided three ways:- Pseudo – random frequency band hops Authentication Encryption.
- 14. Bluetooth connection are established via the following techniques: Standby page/Inquiry active hold sniff park
- 15. USAGE MODEL
- 16. . Bluetooth model is used voice/data access points Peripheral interconnects Personal area networking(PAN)
- 17. VOICE /DATA ACCESS POINT Voice/data access points is one of the key initial usage models and involves connecting a computer device to a communicating device via a secure wireless link.
- 18. PERIPHERAL INTERCONNECTS The second category of uses, peripheral interconnects, involves connecting other devices together
- 19. PERSONAL AREA NETWORKING The last usage model, personal are networking (PAN),focuses on the breakdown of personal networks.
- 21. It separates the frequency band into hops. This spread spectrum is used to from one channel to another, which adds a strong layer of security. Up to eight devices can be networked in piconet. Signals can be transmitted through walls and briefcases, thus eliminating the need for line-of-sight. Devices do not need to be pointed at each other, as signals are Omni-directional. Governments worldwide regulate it, so it is possible to utilize the same standard wherever one travels.
- 22. COMPETING TECHNOLOGIES IrDA WIRELESS LAN •For cable replacement, the infrared standard IrDA has been around for several years and its quite widespread. •Wireless LAN based on the lEEE BO2.11b standard are used to replace a wired LAN throughout a building The transmission is high and so is the number of simultaneous users.
- 24. 1.) No line of site restrictions as with IrDA. 2.) Power consumption makes integrated in battery powered devices very practical. 3.) 2.4GHz radio frequency ensures worldwide operability. Tremendous momentum not only within the computer industry but other industries like cellular telephones and transportation.
- 25. APPLICATIONS
- 26. AUTOMATIC Check –in Hotels are testing , or plan to test ,services that allow guests to check in, unlock room doors and even control room temperature with handheld devices equipped with Bluetooth Technology.
