• Bluetooth technology is a wireless protocol for transimitting and receiving data. It uses a frequency-hopping spread spectrum, by means of which it sends chunks of data through a range of 79 frequencies. It allows wireless connectivity for electronic devices, including cell phones, laptops, printers, digital cameras and video game consoles.

  Bluetooth have also created handsfree sunglasses. The sunglasses have a built-in earpiece and the volume control and call answer buttons are located on the arm-piece.http://www.thinkgeek.com/gadgets/electronic/b556/?cpg=cj Bluetooth Handsfree Sunglasses]

• How It Works

  Much like you would connect printers, digital cameras and other electronic devices to a computer with cords, Bluetooth technology replaces the cords and connects these items without wires. The individual device, such as a hands-free headset, sends out a radio signal which a cell phone or other device picks up wirelessly. Both devices must be Bluetooth capable for the connection to be made.

• History and Development

  Development on Bluetooth began in 1994 in Sweden and was officially launched in 1998 with the formation of the Bluetooth Special Interest Group. The technology has evolved since the initial release, improving signal strength and lowering power consumption.
