In today's society, communications play a very important role, since it allows us to continuously communicate and interact with other people and companies. It could be said that without communications life would not be as we know it. Over time, the need to communicate became ever greater, which is why companies and manufacturers sought to evolve and offer more and better equipment and services to users. But the evolution of mobile phones begins in 1972 when Martin Cooper turned the phone into an artifact that was impossible to get rid of.
These devices altered the way in which people communicate, as well as their social behavior. Over the years, mobile phones have evolved and continue to do so dramatically. They started out just as analog “bricks” (named for their shape and size), and are now small, digital, and feature-rich devices.
The first mobile phone
The first mobile phone was the Motorola DynaTAC 8000x which appeared was launched on the market in 1983. It weighed 780 grams and had dimensions of 33 x 9 x 4.5 cm. It was an analog phone with a tiny screen. The battery had a life of no more than one hour of conversation and 8 hours of standby.

The sound quality of this phone was very poor, it was a heavy device and with little aesthetics. However, some people came to buy it for a price of $ 3,995, becoming a luxury item.
As expected, the people in using them were entrepreneurs, executives and people with a lot of money to buy it. Since the economic development of a company requires effective communication with employees, suppliers, customers, governments and regulatory agencies. This service had a high cost and since there was no competition in the market, prices did not drop.
First-generation of mobile phones
The first generation begins with the Motorola DynaTAC 8000X in the 1980s. These devices were analog technology for use by voice commands. The technology of this generation was AMPS (Advanced Mobile Telephone System).
The second generation of mobile phones
In the 90s, new mobile phones with digital technology emerged and benefits were highly valued. They had longer battery life, more definition and a significant improvement in sound quality. These phones had a new function, they were able to send and receive text messages (SMS), although it had not yet become popular.
Ordinary people became part of the user list, as prices were reduced by competition between companies. The dominant technologies were GMS, CDMA and PDC. The latter was only used in Japan.
Second generation phones operated under GMS, CDMA and PDC technologies. They were also able to send text messages (SMS).
The third generation of mobile phones
This generation had the incorporation of old technology but with a new design. These phones reached many more users, mainly due to lower prices. It was also the appearance of the SIM card, where all the information of the device line is located.
Consumption became large, mainly due to the low prices and very good promotions. However, social status still existed and the mobile phone has a certain symbolic value of class membership.
The third generation of phones appeared with the SIM card, which had all the information on the line. These were already devices capable of capturing photographs, filming a few minutes, color screens, fast Internet connection, multimedia messaging and email mailbox.
Users already had an infinite market for mobile phone models that even incorporated digital cameras. These were devices capable of capturing photos, filming a few minutes, color screens, a fast Internet connection, multimedia messaging and an email box.
In Japan, UMTS-based 3G mobile phones were launched. The main change was that a second (front) camera was added to make video calls so that you could see and talk to a person at the same time as the mobile phone. After this, other communication standards appeared, making them faster and more functional.
Smartphones, the fourth-generation mobile phones
The 4G communications changed completely and forever the way in which people use their phones. The smartphone or Smartphone was basically a union between a phone and a computer, breaking the pattern of content consumption that we have used for years.
Fourth-generation phones are devices that changed things. These smartphones are capable of transmitting at high speeds, you can even view content in high definition.
The 4G transmission speed allows us to view HD content, music streaming and more. And of course, if something has to do with work, everything is done much faster and without complications.
