BLUETOOTH

Introduction:-
A proposed radio frequency specification that many portable devices will use for short-range wireless communication is known as Bluetooth. Bluetooth device such as laptop computer, handheld computer, pagers, cellular telephones, fax machines, and printers are widely communicated with each others pc to internet. To use Bluetooth communication each device must have chip and be within a specific range (about 10 meter to 100meter). Company is observed to expect Bluetooth to be implement in billion of devices up to date in 2005.Bluetooth are published by company consortium called the Bluetooth SIG (special Interest group).It is developed by same engineering at Ericsson. Bluetooth is a most popular technology that enables short-range wireless communication between varieties of electronic devices. it allow devices to talk wirelessly with one to another, Intel, nokia, IBM and Toshiba joined erosion as the founding members of SIG, and more than 8000 companies have signed on since Bluetooth specification and logo, manufacture must be member of SIG company which devices must meet outlined qualifications. Bluetooth wireless devices are used world wide which is communicate with one another device. Bluetooth provide short-range wireless capacity. If we using the 2.4GHZ band available in universe for on licensed low power uses 2 Bluetooth devices within 10m of each other can be share up to 720kbps of capacity. Bluetooth is support audio; graphics are transferring one device to another device. Bluetooth are used in these devices like telephones, headset, cordless, none stereos, cellophane and others devices. Bluetooth wireless specification gets it name from Harold blatant (it transferred to Bluetooth) 10th-century Danish kings who use diplomacy to negotiate a trace between two feuding factors. Today’s world is at the 21st century’s Bluetooth become popular to leading transferring data. The some of the example are mobile phone, headset, USB, en drive keyboard mouse, laptop, phone, and pod etc.

Importance:-
People have been made great advancement in technology. Technology has been improved in the world day by day. After the invention of Bluetooth technology other technology are looking for lunch. When the Bluetooth software begins to developed and famous feature provides in mobile phones. With the helped of Bluetooth many application are made. It includes application software data transmission software for communication for games. We can find more application free of cost while using the normal changes some of the software has annual subscription fees. Bluetooth software are used to transferring the data or file from one phones to another phones. Data can be transfer when other Bluetooth is enabling in the phones or other devices. Picture is transfer easily or faster than others. When Bluetooth is enable we can print out the data such as types of data is transfer is possible with the help of software. We can connected internet by using device which connection with the laptop and provide both devices Bluetooth must be enable and synchronized by via Bluetooth.

Strength:-
Bluetooth has low range of 10meter and information transfer rates up to 3mb (375 kilobytes) per second; Bluetooth technology was suitable for transmitting file like text document, picture, audio, and video.3mb can be access the video and higher quality picture. After 3.0 are introducing this will be change .10mbps seed is required to handle this video, TV signal.

Security issue:-
Bluetooth can operate three security models.
· Mode1 is not security.
· Model 2 serve security at the service level and the channel is build.
· Model 3 provides security at the lime level, before the cannel is built.
It is uses the Bluetooth address to recognize a particular thing and log that transaction when that is can create privacy concerns. The pin number is fist give priority.
