Bluetooth is called a technological standard that makes it possible to transmit data and voice between different devices through a secure radio frequency.
Bluetooth is a technological specification for wireless networks that allows the transmission of voice and data between different devices using a secure radio frequency ( 2.4 GHz ). This technology , therefore, allows communications without cables or connectors and the possibility of creating wireless home networks to synchronize and share the information that is stored on various computers.
In this way, for example, one of the most common situations in which the use of Bluetooth occurs is when two acquaintances are in the same room and want to exchange photographs that they have on their respective mobile phones. In this case, they connect Bluetooth and "pass" these images quickly and easily without having to resort to an Internet connection.
And it is common for Bluetooth and WiFi connection to be confused or contradicted. However, it must be made clear that both cover different actions and fields that are absolutely compatible and equally useful for any user of portable devices such as the aforementioned smartphones as well as PDAs or tablets, for example.
Emergence of the Bluetooth standard
The term Bluetooth ( "Blue Tooth" in English, although the name comes from the Danish and Norwegian king Harald Blåtand , translated as Harold Bluetooth ) is the commercial and popular name for the IEEE 802.15.1 wireless communication standard. The first company to investigate this technology was Ericsson , in charge of leading a group that, over time, added IBM , Nokia , Microsoft , Motorola and other companies that supported the standard.
Computers, mobile phones and digital cameras are some of the devices that can communicate using Bluetooth technology (provided their models allow it).
It is possible to share information between two phones using Bluetooth connectivity.
Different classes
There are three classes of Bluetooth: Class 1 (with a range of approximately 100 meters), Class 2 (10 meters) and Class 3 (1 meter). Specialists consider that, in the coming years, all technological equipment will have the ability to communicate with each other thanks to the standard.
It can be said that the hardware that makes up 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 an interface processor).
Bluetooth battery
In addition to all of the above, we cannot ignore the existence of other terms that also make use of the term that we are now analyzing. Among those is, for example, the Bluetooth stack concept, which we can specify as an application whose fundamental mission is to carry out the management of each and every one of the services offered by the aforementioned Bluetooth port .
Among the batteries of this type we would highlight the Widcomm, which was the first to appear on the market, or BlueSoleil. All this without forgetting the IwBT, the BlueZ or the Affix. Two stacks, the latter that have been created basically to be able to work with them in the Linux environment.
