Bluetooth is a technology specification for wireless networks that allows transmission of voice and data between devices using a secure radio frequency ( 2.4 GHz ). This technology therefore allows communication without cables or connectors and the ability to create home wireless networks to synchronize and share the information that is stored in different computers.
Thus, for example, one of the most common situations when using bluetooth occurs is known when two are in the same room and wish to exchange photographs with their respective mobile phones. In this case, connect the bluetooth and “pass” such images quickly and easily without having to resort to what is an Internet connection.
And it is common to get confused or Bluetooth wireless connection and is in conflict. However, we must make clear that both cover different actions and fields that are absolutely compatible and equally useful for any user of portable devices such as smart phones or smartphones cited as PDA’so tablets, for example.
The Bluetooth word ( “Blue Tooth” in English, although the name comes from the Danish and Norwegian King Harald Bluetooth , translated as Harold Bluetooth ) is the commercial and popular name of the wireless communication standard IEEE 802.15.1 . The first company to investigate this technology was Ericsson, responsible for leading a group that, eventually, joined IBM, Nokia, Microsoft, Motorola and other companies that support the standard.
Computers, mobile phones and digital cameras are some of the devices that can communicate via Bluetooth technology (provided that their models permit).
There are three classes of Bluetooth: Class 1 (with a range of about 100 meters), Class 2 (10 meters) and Class 3 (1 meter). Experts believe that in the coming years, all technological equipment have the ability to communicate with each other thanks to the standard.
It can be said that the hardware that forms a Bluetooth system has two parts: the radio device that modulates and transmits the signal, and the digital controller (with CPU, a digital signal processor known as Link Controller and processor interfaces).
In addition to the above we can not ignore the existence of other terms that also make use of the term that we are now analyzing. Among those found, for example, the concept bluetooth stack that can specify that it is an application that has as its fundamental mission to carry out the management of each and every one of the services offered by the said port bluetooth.
Among the batteries of this kind we would highlight the Widcomm, which was the first that appeared on the market, or BlueSoleil. All this without forgetting the IWBT, the BlueZ or Affix. Two piles latter that have basically created to work with them on what is the Linux environment.
Notably, as mentioned above, Bluetooth is often compared to WiFi , another technology that lets you share information wirelessly, although both have different strengths standards.
