Bluetooth
Bluetooth is a wireless technology developed by Ericsson that is designed to be a cable replacement. It operates on the 2.4GHz frequency band, like WiFi, and is officially known as IEEE standard 802.15.1. It is most commonly used with wireless headsets and car kits, but can also be used for network access, moving files from one device to another, or with wireless input devices such as a mouse and keyboard - among many other uses. These other uses are dependent on the Bluetooth profiles that are supported by the devices in question. There are multiple versions of the Bluetooth specification in use, and in order for full functionality to be possible, the devices on both sides of a connection must be of the same version. This is not to say that a Bluetooth 1.1 headset, for example, will not work with a Bluetooth 2.0 phone - it will. It is only to say that in order to enjoy the benefits of Bluetooth 2.0's features, such as faster connection times, a Bluetooth 2.0 (or later) headset would have to be used.
