Cell phones are called that because the physical area they cover is in a cell format. The origin of the cell phone is said to be back in 1973 when the mass consumer electronics company Motorola launched the first portable cell phone.
Today, the number of cell phone models entering the market is virtually limitless, and their sales generate hundreds of billions of dollars a year, making them the most widely used electronic device in the world.

As we can see in any city or town, it is almost impossible to find a person without a cell phone or smartphone in hand.
This last decade has seen the birth of the smartphone as we know it today, a mixture of computer and cell phone, offering features that we could not even dream of in the days of the Nokia 3210, for example.
Another important aspect of this division into cells is that cell phones need less power to transmit and reach any base station covering a smaller area.
By reducing the energy required for transmission, the battery size, and consequently, the weight is reduced. This contributes to the reduction of cell phone size that would not be possible without cell technology.
When you use your cell phone, the phone first locates the base station with the strongest signal and requests a channel.
The base station allows access to the channel, and the call is then accepted. The call is then sent to the local phone network if the call is to a regular phone. Otherwise, it will be transmitted over the mobile network.
There is no doubt that cellular telephony has become in recent years; one of the most common technologies used daily by millions of people around the world.
Almost thirty years of constant evolution in mobile personal communications have allowed this device to become a fundamental part of the daily development of any activity undertaken by the individual.
Inevitably, along with the Internet, mobile phones have become one of the essential elements for anyone’s social life.
It is precise because these fabulous devices bring users a wide variety of features, which are increasing every day in the new models of terminals, which include additional functions to offer the complete service to the consumer.
Today mobile phones have given us the possibility to learn about other types of communication, such as the popular text messages and multimedia messages.
On the other hand, we cannot forget to mention the inclusion of new platforms, such as the incorporation of the Internet and different modes of connectivity between devices, as well as the added features that have begun to be included in mobile phones for years.
With a mobile phone, we not only establish telephone communication, but we can also take pictures, capture video, surf the Internet, play games, listen to music, and a host of other tasks that we can now develop with the terminal.
For all this, besides adding the advance in the technology behind the physical aspect of the equipment, such as the incorporation of new multi-touch screens, virtual keyboards, and others, the cell phone has become much more than its name indicates, to become a true multifunction device.
Before starting this exciting journey, it is important to briefly highlight how the sophisticated technology behind something so commonplace to us, such as mobile telephony, works.
This platform works by using radio waves, which allow you to perform the operations to establish communication from the cell phone to the base that delays the communication.
In this way, it is possible to develop different modes of communication, from a conventional chat through a call, to sending and receiving a text message, to the most modern functionalities that allow us to be connected at all times.
According to the experts’ opinion, the pioneers in the field of mobile telephony for civilian use began their development path in the distant 1940s, when in the United States, the significant advantages that the use of this type of technology could bring in the daily lives of citizens were glimpsed.
So it was that in the twilight of the ’40s, analog radio systems began to be used, which worked through amplitude modulation, ie, AM frequencies, and then began to use frequency modulation, ie, FM waves, thus achieving a more excellent range and accuracy of service.
In those early days, the HF and VHF bands were used to provide the population with a means of mobile communication, which they could take with them when they left their homes and offices, which meant maintaining constant communication.
However, in those early days of mobile telephony, the consumer response was not entirely satisfactory. This was mainly due to the exaggerated size and weight of the first cellular telephone equipment, and of course, also to the high value that the devices possessed, which were beyond the economic possibilities of the American middle social class.
In general, this type of device was designed to be used only in automobiles, since the radio equipment was installed inside the trunk of the vehicle, from where a cable came out that communicated the telephone receiver inside the driver’s cabin.
Despite their low popularity, this equipment remained in force for several decades, precisely from 1946 to 1985, when finally significant technological changes came to the market, which managed to evolve mobile communications by leaps and bounds.
