A bluetooth headset

Bluetooth is a wireless technology for exchanging data over short
distances. The chip can be plugged into computers, digital cameras and
mobile phones. Find out more about Bluetooth in this short guide.

WebWise Team | 10th October 2012

Bluetooth is a way of exchanging data wirelessly over short distances, and
is an attempt to do away with your computer’s jungle of wiring.

Using a special radio frequency to transmit data, it creates a short range
network. It is very secure and can connect up to eight devices (items of
electronic equipment) at the same time. The chip can be plugged into items
such as computers, digital cameras, mobile phones and faxes.

Bluetooth is particularly convenient in certain situations – for example,
when transferring files from one mobile phone to another without cables.
Sending music and photos between a PC and a mobile phone is another useful
application.

*How do I use Bluetooth?*

You need to check that your device is able to use Bluetooth. You can use a
dongle - something which plugs into your computer to enable it to use
Bluetooth.

*Bluetooth* is a wireless technology standard for exchanging data over
short distances (using short-wavelength radio transmissions in the ISM band
from 2400–2480 MHz) from fixed and mobile devices, creating personal
area networks (PANs) with high levels of security. Created by telecom
vendor Ericsson in 1994,^[2] it was originally conceived as a wireless
alternative to RS-232 data cables. It can connect several devices,
overcoming problems of synchronization.

Bluetooth is managed by the Bluetooth Special Interest Group, which has
more than 18,000 member companies in the areas of telecommunication,
computing, networking, and consumer electronics.^[3] Bluetooth was
standardized as *IEEE 802.15.1*, but the standard is no longer maintained.
The SIG oversees the development of the specification, manages the
qualification program, and protects the trademarks.^[4] To be marketed as a
Bluetooth device, it must be qualified to standards defined by the
SIG.^[/citation needed/] A network of patents is required to implement the
technology and are licensed only for those qualifying devices.
