| Bluetooth technology is a radio-based wireless | | | | exceptionally low power consumption property. This |
| communication technology, by the dint of which the | | | | wireless communication technology enables a wide |
| cable connections of the modern hi-tech devices have | | | | range of electronic devices, like a digital camera, a |
| been completely cut off - thereby maintaining a high | | | | PDA, a mobile phone and a laptop, to get wirelessly |
| degree of efficiency with utmost security. Each | | | | interconnected and coordinated to perform a wide |
| Bluetooth enabled electronic device is cent percent | | | | varieties of tasks simultaneously with astonishingly high |
| capable to successfully communicate, at a time, with | | | | degree efficiency. The Bluetooth technology has cast |
| as many as seven other Bluetooth enabled devices | | | | a serious favorable impact on the modern industrial, |
| within a short range of distance - ranging from 1 meter | | | | medical, and other scientific aspects - accelerating the |
| to 10 meters depending on the radio class. In such | | | | scientific advancement to a far higher pace. |
