| Purchasers of mobiles know what the Bluetooth is | | | | gsmfavorites.com, it is "Bluetooth is extremely |
| all about. For them this is a device through which | | | | secure in that it employs several layers of data |
| they transfer data and information. But very few | | | | encryption and user authentication measures. |
| people know - what the Bluetooth is all about? | | | | Bluetooth devices use a combination of the |
| And what is the specifications and characteristics | | | | Personal Identification Number (PIN) and a |
| of the new technology. Bluetooth is a short-range | | | | Bluetooth address to identify other Bluetooth |
| radio frequency (RF) technology that operates at | | | | devices. Data encryption (i.e., 128-bit) can be used |
| 2.4 Ghz. The Bluetooth enabled devices is capable | | | | to further enhance the degree of Bluetooth |
| of transmitting voice and data. And it works | | | | security. The transmission scheme (FHSS) |
| better at the range of 32 feet (10 meters). | | | | provides another level of security in itself. Instead |
| Another question that is being asked very often | | | | of transmitting over one frequency within the 2.4 |
| is : How is Bluetooth used? The answer according | | | | GHz band, Bluetooth radios use a fast |
| to the is, "Bluetooth can be used to wirelessly | | | | frequency-hopping spread spectrum (FHSS) |
| synchronize and transfer data among devices. | | | | technique, allowing only synchronized receivers to |
