Concept in Definition ABC

The concept of bluetooth It is relatively new and it is a term that comes from the English language but has already been incorporated into the Spanish language as one more as a consequence of its widespread use. Its diffusion is intimately linked to the extension of the new technologies and Internetwith whom you interact.

A Viking king names one of the systems of communication The world's most popular short-distance wireless.

Because the name of Bluetooth comes from Harald "Blue Tooth" Gormsson, who reigned in Denmark shortly before the year 1000

The reason was that good old Harald unified various tribes and converted them to Christianity, making with this a parallelism with Bluetooth, which works on any device regardless of its architecturehardware and the platform software that governs it.

The objective is to be able to connect electronic devices to each other, creating a network, at short distances of a few meters, although the Class 1 specification of Bluetooth allows it to reach 100 meters. It works in the 2.4 GHz band.

Common use of Bluetooth is to connect wireless peripherals to mobile devices, such as hands-free kits or keyboards.

However, computers also incorporate this standard for the same purpose, thereby facilitating a wide market for peripherals such as keyboards, mice, or wireless headphones.

Bluetooth can also be used to share an Internet connection using the technique known as tethering, matching a smartphone with a computer or tablet.

This is possible thanks to the fact that a Bluetooth connection sends and receives data, with which it is easy for us to send the data packets we receive to the computer or tablet mobile via 3G or 4G.

The GIS (Special Interest Group) who is the one who controls the implementation of Bluetooth and decides the standard, has published over the years, various versions and revisions of this standard

The first was in 1998, months after the Bluetooth SIG was created.

Among the most prominent versions we find the 2.0 + EDR, which provides a velocity extended data (the EDR, Enhanced Data Rate), 2.1 that adds secure pairing functionality to the previous one, and 4.0.

The latter introduces bass modes consumption, as many IoT devices powered by non-rechargeable batteries (batteries) incorporate Bluetooth communications. In this way, communication is only active when necessary, saving on energy consumption.

Version 5.0 was released in mid-2016, and it represents a dramatic increase in speed and reliability.

The first devices that implement the Bluetooth 5.0 specification are expected to hit the market between late 2016 and early 2017.

Among the great advantages offered by this transmission are: easy communication between mobile equipment, elimination of connecting cables between the two and the possibility of creating small wireless networks and thus facilitating the synchronization of information between devices personal.

Exemplification from a simple scenario of use of this technology

Surely, we have witnessed or starred in a situation of this type... a person meets a friend and he tells her about some of the musical themes that they are fans of and that he has downloaded them to his cell phone to listen to them through the music player. music of the telephone. Then, as both have cell phones with bluetooth technology, whoever has the songs can send them this way to his friend. No need for cables or anything. It will only be enough to turn on the function on the cell phone and search for the device in question.
