Greetings colleagues from the Hive community, welcome back to my blog, where you can find content from the wide universe of science, mathematics, biology, physics, chemistry, philosophy, and general knowledge accompanied by scientific outreach.

Introduction

I start with an idea, reader friend, the importance of technology since humanity appeared on earth, aroused that need to evolve to do things and improve our quality of life, which is why today it must be clear that technology makes sense and that this refers to the collection of tools that make it easier to use, create, manage and exchange information, with the selected time improvements were applied, also new knowledge is like a paradigm, because technology advances and evolves exponentially every moment of our time, that is why technology is linked with knowledge in the signing of the use of tools, techniques and systems in order to serve a purpose to make life easier and better, especially that technology makes humanity adapt to it and to future changes in the development of its culture.

Bluetooth®

Today in our days we have in our homes, cars, telephones, sound equipment, speakers, several devices with Bluetooth® technology, but we really have knowledge about this type of technology, in reality we only know how to use it, I tell you the following, reader friend, this type of technology was created and developed by luetooth Special Interest Group, Inc. The most unique of the case is that it is fought in order to establish connections with wireless personal area networks (WPAN), which Enables wireless data communication between digital devices, such as a computer or a digital camera, this wireless technology can operate in a range of approximately 9-10 meters approximately.

What fascinates me about this technology in the devices that have it, does not need any type of cable or orientation to connect, over time this type of technology became solid of which it is part of the industry standard measure manufacturing technology, is that today most technological devices have it included in their functions. Among the devices we have sectors of telecommunications and personal computing, such as: mobile phones, laptops, personal computers, printers, wireless speakers or digital cameras, which must be considered as something very important is that the Bluetooth specification defines a communication channel at a maximum 720 kbit / s (1 Mbit / s gross capacity) with an optimal range of 10 m (optionally 100 m with repeaters) since these devices usually work with these specifications at a radio frequency of 2, 4 to 2.48 GHz with broad spectrum and frequency hops with the possibility of transmitting in Full Duplex with a maximum of 1600 hops per second.

Hardware Features

[1] -a radio device: with the function of modulating and transmitting the signal.

[2] -a digital controller: it is made up of a CPU, in addition to a "Link Controller" digital signal processor (DSP), for interfaces with the host device, since it is in charge of processing the baseband and the management of the ARQ and FEC protocols.

Compatible Profiles

-A2DP (Advanced Audio Distribution Profile)

-AVRCP (audio / video remote control profile)

-HFP (hands-free profile)

It is good to know about the technology possen our devices, thanks to them we can educate the handling of it as the case of the use of Bluetooth, which helps us anywhere to process and transmit data, even sharing as a family we can use it on a device of music, the important thing is every day technology leaves us a new teaching and to see the thing, since it develops our culture.
