What Is Bluetooth wireless networking,Bluetooth technology :
It is a new technology with IEEE 802.15.1 specification for wireless exchange of files in the personal sector (WPans).
With this system you can synchronize data, documents, and voice transmissions through signals inside a stable radiofrequency (2.4 GHz) and free, although it has a short access reach and, currently, you can only access to it from about 30 meters tops.
The origin of the word "Bluetooth" was assigned in honor to an ancient Norwegian and Danish king called Harold Bluetooth due to his fame of a good communicator and because he was able to unify several Norwegian, Swedish and Danish tribes, back in his time.
In 1994, the Sony Ericsson company had the idea of designing a new communication alternative in order to be able to get higher fluidity in data transmission, a smaller consume and that it was cheap in synchronizing data between devices such as cell phones, HandDesk, Palms, etc.
Due to this alternative that could improve synchronizing of data, in 1999 a group called Bluetooth's SIG (Special Interest Group) was created, and it was formed by several companies that were interested in the development of this new technology, such as: Nokia, Sony Ericsson, Intel, IBM, and Toshiba, among others. Afterwards, other brands such as Microsoft, Motorola, Lucent and 3COM incorporated; this union resulted in the creation of something that used to be just an idea, Bluetooth.
One of the objectives that was going to be accomplished with this new technology, was the possibility of facilitating even more communication between static or mobile devices, eliminating any sorts of wire or connector connections. It also provides a higher design of some wireless nets and the synchronization between portable equipments, among others.

The way in which it operates its based on a protocol called Bluetooth with which communication can be possible between several devices inside a possible range, performed by a radiofrequency and this is why there is no need for these devices to be aligned to be able to capture the signal.
This technology is divided into three sub classes (1, 2, and 3) and they are in an access range between 1 and 100 meters and it is characterized for reaching a sending speed of up to 720 kb/s; and its optimum range is from 1 to 10 meters.
The frequency that it uses holds a little range between 2.4 to 2.48 GHx and it counts with many jumps on its frequency, and along the specter in which it makes possible the Full Duplex, reaching up to 1600 jumps, which are inside the 70 frequencies in total and with many 1 MHz intervals.
The new version Bluetooth 2.2 will increase considerably the transference speed and it is planned that this system will be able to work with Wi – Fi technology.
The development of a new physical UWB (Ultra Wideband) layer is been studied for the following versions, to be able to acquire a greater band width, better synchronization and a higher compatibility with different electronic devices.
They are also foreseeing that the Wibree technology will be adapted for Bluetooth, achieving communication between this device and other that are much smaller, like in the medicine field, reducing the costs and a consumption merman, with the possibility of using it as an open door to new technologies such as UMTS and the already mentioned, Wi – Fi.
