Okay, so you hear the term all the time right, but still don’t know what the hell it is. Well, Bluetooth is a wireless technology that enables communication between Bluetooth-compatible devices. It is used for short-range connection between computers, PDAs (like the Palm, Blackberry, iPhone), digital cameras, scanners, cellular phones, and printers.The technology is based on radio waves, so there can be objects or even walls placed between the communicating devices and the connection won’t be disrupted. Also, Bluetooth uses a standard 2.4 GHz frequency so that many devices will be compatible with one another. The range of most devices is about 30 feet.
