Bluetooth

An open technology specification for short-range radio links between mobile PCs, smart devices, and other portable machines.

It is a networking technology that enables data to easily transfer from one device to another, and unlike infrared (which requires a clear line of sight to operate properly), Bluetooth operates over a 2.4 gigahertz radio frequency that allows communications through obstacles over distances of 30 feet. This means, for example, that if this technology is combined with MP3, your audio could follow you from your living room to your car to your office. The same data (your preferred songs) could get transferred to different devices (your home stereo, your car radio, and your office audio system). You could also use your phone to create a wireless Internet connection for your laptop.

Bluetooth is a global wireless standard, and it eliminates the need for cords, thus allowing friends and business associates to exchange contact information much more easily. Building on the convenience of using a LAN for file and printer sharing, the creators envision a Bluetooth-enabled home, where the appliances talk to each other using you as the antenna. (Wouldn't you want your datebook to check your refrigerator to be sure there's enough orange juice for Sunday brunch? see: PAN).

On a more practical side, having your PDA, cell phone, desktop computer, and laptop computer automatically synchronize address books and calendars and fitness trackers, etc., just by being in the same room sounds like a good thing.

Historical perspective: Named after the tenth century Danish king Harald Blaatand (which translates to Bluetooth), who unified Denmark and Norway.
