GENERATIONS OF CELLULAR TECNOLOGY
What is 3G? … 4G? … 5G was made to control our minds? Here we explain what each of these means and what they really brought with them for cellular technology.
To begin with, we must explain that the «G» is the abbreviation for Generation, so that is what we will talk about the generations of mobile phone technology, giving a brief, but substantial history of changes and evolution that the company has undergone. technology of that Celu that we use so much.
0G (Generation 0)
To start talking about the evolution of mobile technology, it is important to talk about its origin, Generation 0. This began at the end of the 60s. Where conversations were already generated wirelessly through those of an analogue system of Amplitude modulation (AM), which later evolved to modulated frequency (FM), which is also known as FM radio, with this you could establish communication through radios, or their most popular wokitokis, with these you could talk to people that they were not close but that they were on the same frequency and in coverage, coverage that depended on the power of the antennas incorporated into them; It is when the concept of repeater antennas was born where these devices were supported to be able to expand their reception and reach people even further, these were used, above all, by the military forces to establish their communications.
1G (Generation 1)
Having a clear idea to establish communication wirelessly through antennas, we went to the first generation, where wokitokis were exchanged for telephones, It is here that in 1973 Mr. Martin Cooper made the first call from a mobile phone, although these began to be commercialized in the 80s. They continue to use analog technology but these mobile terminals begin to have a more friendly appearance for that time, Simulating the telephones that many people had at home, The very small detail is that these telephones were large and heavy, reaching a kilogram of weight, and this had to be added that the few antennas which made coverage was very little and focused only on large cities. In addition, due to its high costs, both the device itself and the service, this device was only available to a few
2G (Generation 2)
Observing the projection of mobile telephony, in the 90s this technology began to develop its potential, starting with an abrupt change in its technology, in which it went from analog to digital, with this the precision of information and its efficiency, also the quality of voice in calls and giving rise to the next generation.
There is already more coverage of the cellular network and the number of users who use these types of devices begins to grow.
Thanks to computer globalization and the arrival of the internet, the idea of connecting mobile phones with the world was born and this is achieved through the GSM (Global system for mobile communications) also reaching the text messages that we continue to use today.
With so much demand from people wanting their mobile, the manufacture of these begins to be simplified by making them smaller, more affordable and more tools such as cameras, mp3 players and multimedia players are incorporated, allowing the sharing of different types of files.
As more and more people begin to have their Celu, since there is greater cellular network coverage and roaming is created worldwide, which is the service that allows you to use your mobile phone abroad for calls and text messages and that today is still used even for the internet connection.
3G (Generation 3)
In this generation it was launched in 2003, it is in this generation where the exploitation of the internet begins and mobile phones could not be exempt from taking advantage of it, therefore the tools are improved to get the most out of access to the web and everything. that this brings like social networks, instant messaging, access to email, video conferences, including GPS; This is where two important concepts for telephones are born, the app (application) and the smartphone.
In this generation, the antennas have better power to give a better experience to its users, especially in the use of internet connection applications and something begins to put aside with which I start this, the calls, since the mobiles begin to be more used for access to apps and the internet, because a tool that integrates with great acceptance to mobiles is Wi-Fi.
4G (Generation 4)
Launched in December 2010, this generation is also called the generation of smartphones, since these are the ones that can get the most out of the cellular network and its high speed of internet access, which compared to the previous generation is 10 times faster, a speed comparable to that of fiber optics, it is a bandwidth so great that it allows users to do things like watch HD television. If we talk about game apps, we have the one that was so popular that it took several world records, including being downloaded the most times in its first month, with 130 million downloads, the Pokémon Go.
As for mobiles, there is much more variety and competition, improving, above all, their image quality since sharing multimedia content on social networks and streaming, such as the popular YouTube, is something that becomes almost a necessity, since everyone wants a like.
5G (Generation 5)
Although in 2021, which is when we publish this entry, the fifth generation is just being implemented, it promises to be up to 100 times faster than current wireless systems, offering lower latency and greater reliability.
Relying on the antennas of the previous technology and implementing those of this generation, it wants to guarantee better connectivity from more places and with this reach a greater capacity for users and devices, allowing them to be connected to more terminals at the same time and making the most of the Internet of things (IoT), and no, it does not connect to your brain to control you, it only connects devices with an internet connection such as the TV, the refrigerator, your car or the light lighters, thus giving us many possibilities but not to control your mind.
In 5G we see a scalable infrastructure, which means that it can grow continuously and smoothly and above all, willing to always be growing.
