Bluetooth has completely revolutionized the world of wireless technologies. Bluetooth products allow you to connect to multiple devices, wirelessly. They can also transfer data from a longer distance and an infrared device from other wireless devices.
This low-power device uses radio signals to communicate and transfer data. The most effective current beach for standard Bluetooth use is 10 meters (33 feet). They have developed a high-power Bluetooth device with communication capabilities of more than 100 meters. Electronic devices that can be used with Bluetooth are: laptops, mobile phones, digital cameras, audio equipment and printers eliminating any cable work. They also contain the ability to connect up to 8 peripherals, if all are in the user range.
Ericsson, IBM, Intel, Nokia and Toshiba are the founders of Bluetooth technology. Together, they formed a special committee called Bluetooth Special Interest Group in 1998. In 1999, the following companies joined this committee: 3Com, Lucent Technologies, Microsoft and Motorola.
Where does the Bluetooth name come from? A Scandinavian king of the 10th century was very well known for his efforts to unify people form Denmark, Norway and Sweden. At that time, many wars come off from different regions, Herald Bluetooth wanted peace and unity among all. That’s why the Bluetooth device has received this name. They unify many different industries in a wireless device, using many different industries such as mobile phones, computer science and automotive markets.
The frequency levels of a Bluetooth device are between 2,402 GHz at 2.40 GHz. This differs from any industrial, scientific or medical device (ISM). The signals at 1 Mili Watt can be sent between the devices provided they are in the range.
Although Bluetooth devices are quick and practical users need to be aware of the possibilities of security threats. Bluetooth devices use and ad hoc network that allows connected devices to communicate directly with other devices, unlike other wireless devices using a wireless access point (WAP). This is where the threat of safety in place. If you keep your security software updated, the threat of computer hackers is eliminated.
