Bluetooth

Bluetooth, what is that? What this means is that teeth have a blue color?
Bluetooth now we often use the mobile phone, computer, PDA.
Below is a review of Bluetooth, which is taken from various sources.

Bluetooth is a specification for industrial personal area network (personal area networks, or PAN) without cable. Bluetooth connects and can be used to make exchange of information between equipment. 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 is capable of providing service data and voice communication in real-time between bluetooth host-host with the distance terbatas.Kelemahan this technology is a short range and ability to transfer data to a low.

The name "Bluetooth" is derived from the name of the king at the end of the tenth century, Harald Blatand that in the UK also called Harald Bluetooth because of the possibility that dark-colored teeth. He is the king of Denmark who have succeeded to unite the tribes before the battle, including the tribe's territory that is now called Norway, and Sweden. Even Scania region in Sweden, where bluetooth technology is also found, including local authority. Ability as a unifier king was also similar to the bluetooth technology, now that you can connect a variety of equipment such as personal computers and mobile phones. [1]
While the bluetooth logo comes from the fusion of the two-letter German analog with the letter ÚH and B (short for Harald Bluetooth), namely (Hagall) and (Berkanan), which later merged.
Start from the beginning as Bluetooth is a wireless communication technology (without cable) that operate in the frequency band 2.4 GHz unlicensed ISM (Industrial, Scientific and Medical) using a frequency hopping tranceiver is capable of providing service data and voice communication in real-time between bluetooth host-host with the distance range of services that is limited (about 10 meters). A Bluetooth card that uses radio frequency standard IEEE 802.11 with a limited distance services and data transfer capability is lower than the card for Wireless Local Area Network (WLAN).
The establishment of Bluetooth was started by 5 large companies Ericsson, IBM, Intel, Nokia and Toshiba established a Special Interest Group (SIG), which launched this project. In July 1999 a document bluetooth specification version 1.0 was launched start. In December 1999 started making the document more bluetooth specification version 2.0 with additional 4 new promoter that is 3COM, Lucent Technologies, Microsoft and Motorola. Currently, more than 1800 companies in various fields to join the consortium as a technology adopter bluetooth.
