Bluetooth is a standard developed by a group of electronics manufacturers that allows any sort of electronic equipment from computers and cell phones to keyboards and headphones to make its own connections, without wires, cables or any direct action from a user .

Bluetooth is a low bandwidth wireless networking technology designed primarily to replace cables for communication between personal computing / communication devices. It is intended to be used for both voice and data communications. Bluetooth is a very common standard for wireless communications between cell phones and PDAs, headsets.

Scandinavian countries have been leading the world in wireless communications for a long time now; andBluetooth technology was named after a Scandinavian historical figure: King Harald Bluetooth, a famous Danish king of the 10th century; who united Denmark and introduced Christianity to the country.  

Bluetooth was initiated by Ericsson, IBM, Intel, Nokia and Toshiba in early 1998. These companies later formed a special interest group known as the Bluetooth SIG. Today, many companies are members of the Bluetooth;and all are committed to developing and supporting theBluetooth standard.  Bluetooth  became an IEEE (Institute of  Electrical and Electronics Engineers) standard during 2002. Acceptance of Bluetooth as an industry standard is important for both consumers and manufacturers alike, because of the promise of interoperability attracts more companies into the market and lowers prices.

Bluetooth will be used for personal area networks: very small range networks between cell phones, PDAs, MP3 players, etc. and computers. The built-in voice channels will allow cordless telephony and headsetapplications. PDA-computer synchronization, wireless home networking, connection of keyboards, modems, cameras etc. are all possible.

Small radio chip plugged into the devices to be connected.

Chip can be in-built or connected externally.

Just has to click on the icon and the device is connected.

Avoid interference - uses frequency hopping technique.

Synchronization at bit level. Combination of circuit and packet

switching. Uses one-third power required in

mobile phones - 3mWatt.

Cable replacement technology. Uses radio waves in 2.4Ghz band . Works in small confined area (10-

15m). Able to support speed of 1-2 Mbps

today. Chip sets are relatively inexpensive,

$10 to $20today.

• Mobile Phones •Video Games• Keyboards• Headsets• PDA’S• Bluetooth USB port

Bluetooth supports both voice and data. According to Bluetooth spectrum:-

•The voice channels support 64Kb/s.•An asymmetric data rate is 721Kb/s.•Symmetric data rate is 432.6Kb/s.  

It has two level of security:

# PIN code

# Encryption

Bluetooth in office replace tedious task of networking.

Connect peripheral wirelessly View images on mobile phones

without connecting wires. Connect wireless headset to mobile

phone. Can exchange business documents

instantly.

ERICSSON and NOKIA launched bluetooth headset.

NOKIA & FUJIFILM developed mobile imaging technology.

ALCATEL one touch 700 GPRS,WAP, bluetooth.
