Bluetooth is the industry specification for personal area network (PAN or personal area networks) without wires. Bluetooth connects and can be used to carry out the exchange of information between devices.
Spesifiksi of Bluetooth devices is developed and distributed by the Bluetooth Special Interest Group. Bluetooth operates in the 2.4 GHz frequency band using a frequency hopping traceiver capable of providing voice and data communication services in real time between the hosts with a distance terbatas.Kelemahan bluetooth technology is a short range and low data transfer capabilities.
The presence of Bluetooth makes a person no longer mess with any cables, any color, to where, and which must be plugged into. Antarperalatan interconnection function can be replaced by bluetooth chipset that is placed on a built-in electronic equipment related.
The name "Bluetooth" is derived from the name of the king at the end of ten centuries, Harald Blatand that in England also called Harald Bluetooth. Connotation is not so far wrong, because according to mythology, supposedly Bluetooth-haired and dark-skinned. He likes to eat blueberries or strawberries, it is worth it when teeth Blatand a bluish or blue tooth.
He is the king of Denmark who has managed to unite the tribes who had previously fought, including the tribe of what is now called Norway and Sweden. Even the Scania region in Sweden, where Bluetooth technology is found also included territory. Capabilities as a unifying king also similar to Bluetooth technology now that can connect a variety of devices such as personal computers and mobile phones.
While the Bluetooth logo come from the union of two German letters are analogous with the letter H and B (stands for Harald Bluetooth), namely H (Hagall) and Runic letter (Blatand) which are then combined.
Beginning of Bluetooth is a wireless communication technology (wirelessly) operating in the frequency band 2.4 GHz unlicensed ISM (Industrial, Scientific and Medical) using a frequency hopping transceiver capable of providing voice and data communications services in real-time between hosts bluetooth with limited service reach distance (about 10 meters).
Bluetooth in the form of card that uses the IEEE 802.11 standard radio frequencies with a limited service range and the ability to transfer data is lower than cards for Wireless Local Area Network (WLAN).
Bluetooth formation promoted by five major companies Ericsson, IBM, Intel, Nokia and Toshiba formed a Special Interest Group (SIG), which launched this project. In July 1999 document bluetooth specification version 1.0 was launched.
In December 1999 resumed document creation bluetooth specification version 2.0 with the addition of four new promoters namely 3Com, Lucent Technologies, Microsoft and Motorola. Currently, more than 1800 companies in various fields join a consortium as bluetooth technology adopter. Although the standard Bluetooth SIG is now 'owned' by the promoter group but he is expected to become an IEEE standard (802.15).
Currently more than 2,000 companies or members of the community joined the SIG bluetooth lovers. With bluetooth they offer more value to their products to target market customers on board. In the next 2-3 years, bluetooth certain to be mass produced and integrated into a variety of office equipment products, household, health, medical, automotive, music, games, and entertainment. Bluetooth will drastically change your lifestyle and how the office equipment and household utensils.
