Setting up a communication networking between different devices can be a cumbersome task; basically, the more devices you want to connect, the more wires can get in your way. The advent of Bluetooth technology has done away with the necessity for a lot of those networking wires.
Facts
Bluetooth is a wireless networking protocol that allows you to connect different devices. Two or more Bluetooth-enabled devices can communicate without the use of a physical connection.
History
The term "bluetooth" is a nickname given to this wireless protocol around the time it was introduced in 1999. It is named after a Danish king remembered for having the ability to unite warring tribes at the end of the first century and for having a famous "blue tooth."
Significance
Bluetooth can operate between devices made by the same manufacturer and devices made by different manufacturers as well.
Function
Just as with a 802.11 network, Bluetooth uses radio signals to create the bandwidth over which the devices communicate information.
Types
There are two popular classes of Bluetooth devices: the more common Class 2, with a communication range of about 30 feet, and the less common Class 1, with a range of about 300 feet.
