• If you use a cell phone or a laptop computer on a regular basis, you have probably heard of Bluetooth. It has many things in common with another form of wireless technology, Wi-Fi, but a few key differences


    Bluetooth is a wireless method for sending and receiving information for a device such as a keyboard, mouse or cell phone headset.


    Bluetooth transfer speeds are not as fast as Wi-Fi, but it uses relatively little electricity to send and receive information. Bluetooth generally has a shorter range of about 30 feet.


    Basic Bluetooth can theoretically transmit at up to 1 megabit per second, or 125 kilobytes (KB) per second. Bluetooth 3.0 HS (high speed) has a theoretical speed of up to 24 megabits per second.


    Windows users must have at least Windows XP SP2 (Service Pack 2). Mac users must have at least operating system (OS) X 10.2. Linux users should have at least kernel 2.4.6 for built-in support.


    Many laptop computers come with a Bluetooth adapter. You can also buy one for a laptop or desktop. You need only one adapter to connect multiple Bluetooth devices.
