Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.
Bluetooth technology is a wireless method of transferring data between two or more electronic devices. Compatible Bluetooth devices in range of each other automatically connect to one another. You may have seen people walking around wearing Bluetooth earpieces or headsets to speak hands-free via a wirelessly connected phone. While this is a useful feature made possible with Bluetooth, there are several other applications of the technology.

Handheld Devices
Bluetooth technology is also available in portable devices. Many smart phones make use of Bluetooth for wireless Internet and for pairing with other nearby devices. Some GPS devices use Bluetooth to not only helps you with directions, but also to get traffic updates and locate nearby vendors such as restaurants or gas stations. Some cameras and camcorders use Bluetooth wireless to make it simpler for you to transfer pictures and videos from the device to your computer.
PHONE ACCESSORIES
Those headsets you've seen are one of the more prominent uses of Bluetooth technology. They pair with your Bluetooth-enabled Smartphone to allow you to have hands-free conversations, which come in handy when you're looking over reports or driving around. You can also get Bluetooth mini-keyboards to make it easier to type text messages and emails on your phone, and Bluetooth speakers for your phone. Finally, you can connect a call to your car stereo to hear the other person through your speakers.
