One of the oldest wireless technologies, Bluetooth can connect several devices over short distances, offering connectivity without the hassle of cables. Moreover, it has numerous useful applications, such as wireless mobile headsets.

However, the standard can do much more. Speakers can play music from any of several devices in the area, and helmets act as an intercom to let bikers talk over road noise. Take your calls, share information, and listen to music wirelessly with the convenience of Bluetooth.

About Bluetooth

Bluetooth technology uses a wireless system to transfer data over short to medium-range distances. Bluetooth can work from both mobile or fixed devices, and can help to set up a personal area network (sometimes referred to as PAN). The electronics company Ericsson created the technology in 1994 - it was initially conceived as a solution for problems with synchronisation and RS-232 cables. The wireless connection allowed multiple devices to link up at the same time, whereas RS-232 cables had become problematic when considering more than one device. There are so many devices on the marketplace that use bluetooth to their benefit. The most obvious, and one of the first commercially successful examples, is the mobile phone. Bluetooth headsets became extremely popular when they were first released, as they allowed you to automatically connect a telephone call to your hands-free bluetooth headset, from any modern phone that would allow it. More modern, and more interesting applications include the bluetooth biking helmet, which allows data, such as music, or directional instructions to be heard through the speakers built in to the helmet. Wireless headphones use bluetooth too, allowing the wearer to go wire free when they take their music with them. Car stereos have bluetooth connectivity, allowing the user to link his or her music player directly to the car audio system. Games consoles now use bluetooth to transfer data, or connect the controllers to the console. Once again this has the benefit of having no wires, and also very little signal interruption.
