Behind Bluetooth Wireless Device

Bluetooth is the industry specification for personal area networks (personal area networks, or PAN) without wires. Bluetooth connects and can be used to perform the exchange of information between devices.

Spesification of Bluetooth devices was developed and distributed by the Bluetooth Special Interest Group. Bluetooth operates in 2.4 GHz frequency band using a frequency hopping traceiver capable of providing voice and data communication services in real time between bluetooth host-host with limited distance.weakness of this technology is a short range and low data transfer capability.


The presence of bluetooth makes a person no longer mess around with what cable, what color, heading nowhere, and must be plugged in where. The function of the interconnection between the equipment can be replaced by bluetooth chipset that is placed in 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 which in England is also called Harald Bluetooth. Connotation is not so far wrong, because according to mythology story, supposedly Bluetooth-haired and dark skinned. He likes to eat blueberries or strawberries, then it is worth when the tooth Blatand become bluish or blue tooth.

He is the king of Denmark who has managed to unite the tribes that previously fought, including the tribes of the area now called Norway and Sweden. Even the Scania region in Sweden, where bluetooth technology is found to also include territories. King's ability as a unifier is also similar to bluetooth technology now that can connect various devices such as personal computers and mobile phones.

While the Bluetooth logo comes from the German unification of the two letters which are analogous with the letter H and B (short for Harald Bluetooth), namely H (Hagall) and Runic letter (Blatand) which are then combined.

Beginning of Bluetooth is a wireless communication technology (without cable) that operate in the 2.4 GHz unlicensed frequency band ISM (Industrial, Scientific and Medical) using a frequency hopping transceiver is capable of providing voice and data communication services in real-time between bluetooth host-host with limited service reach distance (around 10 meters).

Bluetooth card that uses the IEEE 802.11 radio frequency standard with a limited range of services and lower ability to transfer data from card to Wireless Local Area Network (WLAN).

Bluetooth formation promoted by five large companies Ericsson, IBM, Intel, Nokia and Toshiba to form a Special Interest Group (SIG), which launched this project. In July 1999 document bluetooth specification version 1.0 was launched.

In December 1999 started again making bluetooth specification documents version 2.0 with the addition of four new promoters of 3Com, Lucent Technologies, Microsoft and Motorola. Currently, more than 1800 companies in various fields to join in a consortium as an adopter of bluetooth technology. Although the standard Bluetooth SIG is currently 'owned' by the promoter group but he is expected to become an IEEE standard (802.15).
