It's been more than 20 years since the first mobile phone went on the market, completely changing the possibilities of communication between people and facilitating interconnection at any time and in any place, but in that amount of time, the transformations that have undergone This technological device has been numerous and has evolved to be much more than just a device for calling or sending messages. Today, it is called smart phone.
And the changes do not stop. Such advances are predicted for the coming years, that some experts show an eventual disappearance of mobile phones as we know them today, this to give way to new devices that better adapt to everyday life and that fulfill the same functions as always with many others.
This is the opinion, for example, Shao Yang, representative of the Chinese company Huawei, who has declared to the media his position on the future of mobile phones. Maybe the communication will be somewhere in my pocket, maybe on some screen in my glasses, maybe the music on a device in my ear, there will be many possibilities.
The boom of mobile phones began with the launch of the Motorola DynaTAC 8000, in 1983. It was a heavy equipment almost a kilogram and large that did not last to discontinue and be replaced by new models, increasingly compact and comfortable for the carrier of the team.
The DynaTAC belonged, according to Wikipedia, to the first generation (1G) of mobiles, which was followed by the 2G generation, in the 1990s. At this stage, GSM, IS-136, iDEN and IS-95 communication systems and frequencies were used adopted in Europe were 900 and 1800 MHz. The GSM (Global System for Mobile communications) offers voice and data mailbox functions, but not at the speed that users began to demand. The Motorola StarTAC can be mentioned as belonging to this period.
The 3G generation will soon be born, which provides better services, including internet connection, video conferencing, television and file downloads. The appearance of new brands and models of mobile phones is accentuated during this time, which are seen from the first Nokia to the launch of smartphones, including the Blackberry.
Currently, the fourth generation or 4G is in force, which include equipment such as Samsung Galaxy, Huawei Ascend, Sony Xperia, Apple iPhone, among others.
Just as the first mobile changed the way we communicate, the smartphones They have had another great space to modify the way we develop daily. They are a work, communication and entertainment tool. Wikipedia defines them as a mobile phone type built on a mobile computing platform, with a greater capacity to store data and perform activities, similar to that of a minicomputer, and with greater connectivity than a conventional mobile phone. The term intelligent, which is used for commercial purposes, refers to the ability to be used as a pocket computer, and even replaces a personal computer in some cases.
