SEMINAR ON BLUETOOTH TECHNOLOGY

ABSTRACT Bluetooth is a Radio Frequency (RF) used for short-range, point-to-point and point-to-multi-point voice and data transfer, which enable users to connect to a wide range of computing and telecommunication devices without the need of cables. Bluetooth has emerged as a very popular ad hoc network today. It is a wireless communication technology that permits communication between Bluetooth enabled devices. Bluetooth network applications include wireless synchronization, e-mail/Internet/intranet access using local personal computer connections and applications that can be used for such devices as hands-free headsets and car kits.

INTRODUCTION The original architect for Bluetooth, named after the 10th century Danish king Herald Bluetooth, was Ericsson Mobile Communication. Bluetooth is a short-range wireless communication technology for ad-hoc communication between devices, each of which has a range of around 10m. Bluetooth-enabled consumer devices to enhance wireless connectivity among the array of devices that are anticipated are cellular phones, PDA s, notebook computers, modems, cordless phones, pagers, laptop computers, cameras, PC cards, fax machines, and printers. Bluetooth is now standardized within the IEEE 802.15 Personal Area Network (PAN) Working Group that formed in early 1999. Bluetooth also include vending machines, banking and other electronic payment systems, wireless office and conference rooms; smart homes, and in-vehicle communications and parking.

USAGE MODELS A usage model is a set of protocols that implement a particular Bluetooth-based application. Each profile defines the protocols and protocol features supporting a particular usage model. File transfer. Internet Bridge. LAN access. Synchronization Three-in-one phone. Headset.

ADVANTAGES Multiple Pico nets (scatter mode) are able to connect to each other via the master devices thus increasing the total number of connected devices beyond eight. Limiting range to ten meters helps reduce power requirements making Bluetooth a practical technology Provides a degree of security for communications between Bluetooth devices. Provides overall ease-of-use. Provides greater flexibility and ease-of-use over wireless technologies like IrDA, which require a line of site between devices.

Allows connections to be established through barriers. Tremendous momentum not only within the computer industry but other industries like cellular telephones and transportation.

DISADVANTAGES Early stages of development make Bluetooth an immature technology that will need to prove itself. Bluetooth shares the same frequency range as 802.11b Wireless LAN products (i.e. 2.4GHz) which mean that under some conditions these two technologies will not be able to operate in the same physical space.
