What is Bluetooth Technology
Today, electronics that connect to one another are found everywhere--in the office, home, Car, etc. Keyboards connect to computers, MP3 players to headphones and so on. So, how do these devices connect to each other? Usually the answer is: with wires and cables. But, as you know, wires and cables always result in a tangled mess. Bluetooth wireless technology eliminates many of the wires that clutter our offices, homes, etc., while allowing our electronic devices of today and tomorrow to communicate with one another.
Bluetooth technology is a short-range wireless radio technology that allows electronic devices to connect to one another. Generally, Bluetooth has a range of up to 30 ft. or greater, depending on the Bluetooth Core Specification Version. Newer devices, using newer versions of Bluetooth, have ranges over 100 ft. Bluetooth wireless technology makes connections just like cables connect a computer to a keyboard, mouse, or printer, or how a wire connects an MP3 player to headphones. Bluetooth technology makes these same connections, except it does it without the cables and wires. With Bluetooth there is no more worrying about which cable goes where, while getting tangled in the mess.
Bluetooth History
The name “Bluetooth” and its logo are trademarked by the privately held trade association named the Bluetooth Special Interest Group (SIG). Founded in September 1998, the Bluetooth SIG is a unification of leaders in the telecommunications, computing, network, industrial automation, and Automotive industries. Today, the Bluetooth SIG is responsible for encouraging and supporting research and development in Bluetooth technology. The Bluetooth SIG includes promoter member companies Microsoft, Ericsson, IBM, Intel, Agere, Motorola, Nokia, and Toshiba, plus thousands of Associate and Adopter member companies.
The developers of this wireless technology first used the name "Bluetooth" as a code name, but as time past, the name stuck. The word "Bluetooth" is taken from the 10th century Danish King Harald Bluetooth. King Bluetooth had been influential in uniting Scandinavian Europe during an era when the region was torn apart by wars and feuding clans. A Scandinavian firm originally designed the logo at the time the SIG was formally introduced to the public. Keeping to the same origin as the Bluetooth name, the logo unites the Runic alphabetic characters "H", which looks similar to an asterisk, and a "B", which are the initials for Harald Bluetooth. If you look close enough you can see both embodied in the logo.
How Bluetooth Works
The goal of Bluetooth is to establish a worldwide, universal "language" for devices. Bluetooth uses a standardized wireless protocol for devices to communicate. It forces devices to agree on when bits are sent, how many will be sent at a time, and how the devices in a conversation can be sure that the message received is the same as the message sent. So, you can be positive that any two devices using compatible Bluetooth will definitely be able to communicate with one another.
