Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances effortlessly. This facilitates instant connections between various communication devices, such as mobile phones, desktops, notebook computers, smart phones, hands free headset etc. Bluetooth uses radio transmission (ISM band from 2400-2480 MHz frequency), thus the transfer of both voice and data is in real-time. The sophisticated mode of transmission adopted in the Bluetooth specification ensures protection from interference and security of data.
Bluetooth is managed by the Bluetooth Special Interest Group
