Our online glossary is here to help you make sense of the terminology used in the cell phone industry. It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.
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.
Also known as: "802.15.1"
