What does a mobile phone consist of? The evolution of the telephone: the path from a talking telegraph to a smartphone Telephones and their description

One could only dream about this then. However, progress has taken its toll. It took a little over 60 years for the device, which appeared in the middle of the last century, to acquire the appearance familiar to us today. Let's look at a brief history of the emergence and development of mobile cell phone, as well as cellular communications in general.

Go…

Back in 1947, Bell Laboratories (USA) officially came up with a proposal to create mobile phone. This date can be considered a starting point. It was then that active work on creating a new device officially began.

However, the first mobile phone was not destined to appear within the walls of Bell Laboratories. The first prototype of a mobile cell phone was created by the American company Motorola. This happened in 1973. The creator of the device was engineer Martin Cooper. The weight of the first cell phone was about 1 kg, dimensions: 22.5x12.5x3.75 cm. The device did not have a display. The phone's battery allowed it to operate in standby mode for up to 8 hours, and in talk mode for up to one hour. It took quite a long time to charge the phone (about 10 hours). In 1984, a working model of the DynaTAC 8000X cell phone went on sale. The price of the new product was $3,995. However, despite this, thousands of people who wanted to purchase a new device signed up to buy the device!

In the USSR, the first experimental sample of a cell phone was created in 1957; it weighed as much as 3 kg! Moreover, the device was also accompanied by a base station, which was connected to the City telephone network(GTS). However, a year later the weight of the device was reduced to 0.5 kg.

The first cellular operator in the USSR appeared in 1991. The price of the phone, which was then offered by Delta Telecom, was $4,000, including connection. The device weighed about 3 kg. A minute of conversation cost $1. Moreover, in the period from 1991 to 1995, the number of subscribers of the company reached 10,000 people. In the Russian Federation, the first cellular operator operating using GSM technology, which is familiar today, appeared in 1994.

The number of cellular subscribers has been constantly and steadily growing. In 2009, about 190 million subscribers were registered in Russia. Of course, this number in our country, as well as throughout the world, continues to grow today.

There is no limit to perfection

The cell phone has been constantly improved since its inception. In 1993, the world's first cell phone with a built-in clock was released. Three years later, the German company Siemens began producing devices with a voice recorder and a color display. True, there were only three colors on such displays. In 2000, devices with a built-in camera went on sale. This happened in Japan. Around the same time, phones with a built-in mp3 player went on sale. In 2001, support for the Java platform appeared in cell phones. This made it possible to install many different applications on the devices. Among them is the famous exchange service instant messages– ICQ. The first mobile phone supporting Bluetooth technology was released by Ericsson in 2002. This technology made it possible to exchange various data between phones at a certain radio frequency (wireless). In this case, the phones should be located fairly close to each other. Depending on interference and obstacles, the range of Bluetooth is from 10 to 100 m. At the same time, a phone supporting EDGE technology appeared. It allowed you to access the Internet using your phone. And do this at a fairly high speed. The development of EDGE has pushed the earlier WAP technology into the background. The latter allows you to access the Internet at lower speeds. At the same time, you need to pay for the time spent on the network, and not for the amount of information viewed. The introduction of EDGE technology is the merit of the Finnish company Nokia.

It would take a long time to list all the new functions that appear in the process of improving cell phones. The improvement process continues today. While you are reading this article, another unique device is already being created in the world. For example, a phone that can type input text using only thoughts (“read” your thoughts and turn them into text). By the time such a device is released, it will be useful to know and understand the basic functions of mobile phones that already exist. Let's move on to consider them.

25 main functions

So, let's look at the most common features of modern mobile phones.

Phonebook . This function is a necessary and mandatory thing for any mobile phone. Available in all modern devices. Allows each phone number to have its own unique name. For example, 8-888-888-88-88 – Ivan Petrov. Contacts can be saved in the phone's memory, an additional memory card, or a SIM card. Concepts such as “memory card” and “sim card” are discussed in paragraphs 15 and 19, respectively.

More advanced devices have the ability to save many useful information for each contact (email address, home and work phone numbers, place of work, home address, etc.). In this case, the phone functions as a full-fledged address book.

Call log . The function is extremely useful. Makes it easy to see where and when you called (or were called). Also, using the call log, you can see the duration of any of your calls. Today this function is present in every cell phone.

SMS (Short Message Service) . The same absolutely mandatory service today as the previous two. Allows you to send and receive short text messages in cellular networks. Today this feature is present even in the cheapest models.

MMS (Multimedia Message Service - multimedia message service). This function allows you to send and receive multimedia messages (video, audio, pictures) from one phone to another. It should be noted that the size of the transmitted content is quite limited. Most cellular operators in Russia and the CIS allow you to transfer up to 300 KB of information in one MMS message. Today, the largest cellular operators allow you to send SMS and MMS from their websites for free. You only need to pay for Internet services.

Watch . Today, it is perhaps impossible to find a cell phone that lacks this function. Although, of course, if you want, everything is possible. After all, phones come in every taste and color. A clock is a useful, simple, necessary function. At the same time, no one forbids you to wear your favorite wristwatch.

Stopwatch . What it allows you to do is clear from the name. Stopwatches in modern phones are quite accurate. The function is useful for athletes. May be useful for students during laboratory work.

Timer . The opposite of a stopwatch. Allows you to count down time “backward”, do a countdown. You select a time interval and turn on the timer. At the end of this segment, the timer gives a certain signal (sound, vibration).

Alarm . This function can be used instead of a regular stationary alarm clock. Or as another, safety alarm clock. A very convenient thing. Especially when you are visiting and you need to wake up early in the morning.

Calendar . Useful feature. Often at hand in right moment there is no ordinary calendar. And you need to look at what day of the week it will be, for example, April 10. A couple of quick clicks and you're in the know. Very comfortably.

Calculator . Most often, phones have a simple (non-engineering) calculator installed. It is suitable for some quick simple calculations. When you need to add, subtract, divide, multiply or take a percentage. Having this feature can be really useful. After all, an ordinary calculator is not always available where it is needed now. Today this function is present in almost any mobile phone.

Converter . Allows you to convert various quantities (units of volume, area, length, etc.) from one measurement system to another. This also includes the ability to convert one currency into another at a rate known to you.

Radio . Allows you to listen to publicly available radio stations operating on FM frequencies absolutely free of charge. A necessary function for those who want to constantly stay up to date with events. Who likes to listen to news and favorite programs on the radio.

Flashlight . It will be very useful when you don’t have a regular flashlight at hand. And you will definitely need to highlight something somewhere. You can, of course, highlight it with a bright switched-on display. But a flashlight in this case is much better. Shines brighter, white light. Moreover, unlike the display, it shines pointwise, and not “smeared”.

Photo, video camera . A most useful feature. Present in most modern mobile phones. Sometimes you don’t have a camera or video camera at hand, but you urgently need to capture something. Even if not in the actual best quality. Although one can argue about the quality. There are phones in which the main emphasis is on the extensive camera capabilities. Such devices allow you to obtain photos and videos of very decent quality. Such phones are called camera phones. An example of a camera phone is . It is equipped with an 8 million pixel camera. with LED flash; maximum photo resolution 3264x2448 pixels.

Memory card support . In cell phones, various information (your contacts, audio, video files, photos) can be stored in the memory of the device itself. However, most often the amount of this memory is very limited. Although there are devices with quite decent internal memory. To expand memory, phones are usually equipped with connectors (“slots”) for special memory cards (flash cards or “flash drives”). There are different types of memory cards. Today, the most common slots in mobile phones are microSD and microSDHC flash cards. The former allow you to store up to 4 GB of information, the latter – up to 32 GB.

MP3 player . For music lovers, this function is simply irreplaceable. Allows you to listen to audio files available on the phone (or on the inserted memory card). Moreover, the most advanced phone models in this regard reproduce sound not only in mp3 format. They support AAC, WMA, WAV and some other formats. Devices in which the main emphasis is placed on increased quality of reproduced sound are called “musicphones” (music phones). An example of such a phone is .

Dictaphone . Useful feature. Imagine: you need to record it, but you don’t have time to write it down. Or just lazy. It’s much easier and faster to click the “record” button and save the desired audio file. It is very convenient to record some kind of conversation or conversation. This function will be useful for musicians. You never know where inspiration will come to them. He turned on the recorder and recorded the music he had composed, a vocal part or a song. Fast, simple, convenient.

Internet . Majority modern phones allow you to access the global network. Today there are four main options to get online. These are WAP, GPRS, Wi-Fi and 3G. We will not dwell on each of them in detail. This is a separate big conversation. Note that the most popular in Russia today is GPRS. Although this is not the fastest option for accessing the Internet. WAP technology in the form in which it exists today is not promising. Too expensive and slow. Moreover, you need to pay not for the amount of information viewed (as in the case of GPRS), but for the time spent on the network. Wi-Fi will certainly not be an unnecessary feature in your device. It allows you to surf the Internet at high speed. However, for Wi-Fi to work, special access points, so-called hotspots, are required. They are paid and free. The latter are most often found in various public places. Where there is a constant crowd of people (cinemas, bars, cafes, etc.). It should be noted that their number in all major cities of Russia is growing. 3G is a technology for high-speed mobile Internet access, the so-called third generation mobile communications. Based on the definition, it is clear that the data transfer speed is even higher than in the case of Wi-Fi. This service in the Russian Federation is under development. Moreover, this development is proceeding at a fairly rapid pace. It is quite possible that the 3G feature will soon become very popular among mobile phone users in our country.

“Multi-SIM” . This term refers to the ability of the device to simultaneously work with two or more active SIM cards.

Each mobile operator for one purchased phone number gives you his SIM card. In this case, you yourself choose the tariff at which you will pay for your mobile communications in the future. Of course, each operator has its own conditions (communication prices), its own set of tariffs. It changes periodically. A clear question arises: what is actually good about the function in question? What’s good about it is that it allows you to simultaneously be in touch on two or even three different phone numbers. After all, today there are phones that support three active SIM cards at once. In this case, the numbers can refer to both different cellular operators, and to one. Accordingly, you get the opportunity to “play” with tariff plans. You can choose the most profitable communication option. And in this case, it is enough to have just one turned on mobile phone with you. An example of a phone with two active SIM cards is.

Java support . This feature allows you to install various games and applications on the Java platform on your phone. For those who like to communicate via instant exchange service ICQ messages- a mandatory thing. Moreover, “Asya” allows you to communicate many times cheaper than the short-term service SMS messages. Those who like to play all sorts of racing games, shooters, mini-quests, etc. on their phone cannot do without java support.

Possibility of connecting to a PC (data cable) . Allows you to transfer various files from your mobile phone to your computer and vice versa. Today, phone manufacturers release special programs for their devices. These programs allow you to do many useful things with your phone. They are installed on your computer. Then connect the phone to the PC (using a special cable). Now you get the opportunity, for example, to create backups data from mobile. In addition to this, a number of other interesting opportunities appear. The function is definitely the most useful.

IR port. Infrared port . The technology allows you to transfer data from one device to another. This happens through infrared light waves. Today this technology is almost completely replaced by other, more advanced ones (Bluetooth and Wi-Fi).

Bluetooth . This technology allows you to exchange various information between mobile phones, PCs and other devices on a specific radio frequency. You should know that for such an exchange, the distance between devices should not exceed 10-100 meters (it depends on various interferences and obstacles). Quite a convenient feature. Available on most modern mobile phones.

TV tuner . TV on the screen of your mobile phone. In Russia today this function is poorly developed. The reason is the high cost of receiving a high-quality signal. However, in the world of mobile communications, nothing stands still. It is quite possible that in the near future the situation will change. And with the development of new technologies, we will watch television programs on the screens of our phones. An example of such a phone is .

GPS . Satellite navigation system. Allows you to determine your location anywhere in the world with sufficient accuracy (error 1-2 m). A mobile phone that has this function and is equipped special program, turns into a navigator. A useful feature for traveling and long trips.

Form factor (shape)

So, we looked at 25 main functions of modern mobile phones. But they did not touch upon such an important point as the shape of the device. It is also often called form factor. Based on their shape, phones are divided into:

Classic monoblock . This is a monolithic device that has no moving parts. Sometimes such a device is called a “brick” or “brick”. A monoblock is, for example, .

"Folding bed" ("book") . The body of the device is foldable. Consists of two parts. Reminds me of a folding notepad. Example - .

Slider . The device consists of two parts that move relative to each other. Such a device is, for example, .

Rotator . The phone contains a mechanism that rotates along its axis. An example can be given.

Bracelet . Such a device is worn like a watch on the wrist. An example of such a phone is .

There are phones with other form factors (dual slider, side slider, horizontal clamshell), etc. However, it is the options mentioned above that are most widespread today.

PDA, smartphone or “just a phone” – what’s the difference?

Modern phones are divided into “just phones”, smartphones and communicators (PDAs - handheld portable computers). The fundamental difference between “just phones” and PDAs and smartphones is that the latter two have a full-fledged operating system (Windows Mobile, Symbian OS, Android, etc.). It allows you to install on these devices various programs, expanding the functionality of devices. These can be office software packages, electronic translators, audio and video players, etc. It should be noted that there is no clear division between PDAs and smartphones today. Sometimes these two terms do not separate at all. However, there is an opinion according to which communicators should include devices with a full-fledged operating system and a touch screen. With this classification, it turns out that a smartphone is a PDA with a regular, non-touch screen. There is a device that can easily be classified as a communicator, however, it is positioned by the manufacturer as a completely separate device. This is the famous one from Apple.

This company traditionally positions its products in the market this way. It makes them stand out from the crowd of all similar devices. At the same time, he gives them sonorous names starting with the English letter “i”.

Weight, dimensions and battery capacity

It is impossible not to touch upon the following three characteristics of any mobile phone: weight, dimensions and battery capacity. Most modern mobile phones weigh no more than 100 g. PDAs and smartphones usually weigh more (above 100 g). Also, “increased” weight is typical for “fashion” phones. The reason is that various additional decoration elements are used in their design. For example, gold or special sapphire glass. The most famous company producing expensive “fashion” phones is Vertu.

The dimensions of mobile phones vary greatly. Of course, smartphones and PDAs will be larger than ordinary mobile phones. There are special “women's” or “ladies'” phones. They differ small in size allowing them to fit comfortably in your hand.

An important indicator is the battery capacity. The higher it is, the better. The device will need to be charged less often. The increased weight of smartphones and PDAs is often caused by the large size of the required battery. However, here it is better to pay attention not to the battery capacity, but to the operating time of the phone declared by the manufacturer. Moreover, there are two operating modes: talk mode and standby mode. It is clear that a phone with a large screen and high resolution will have a fairly powerful battery. Especially in comparison with a simpler device. But the “advanced” device will also consume more energy. This means that charging may end faster than with more simple phone. Even if the battery of the latter is weaker. Therefore, be careful! Pay attention to these parameters: the phone's operating time in standby mode and in talk mode. Of course, no one forbids you to look and evaluate the battery power. This will also be useful, especially if you have already had experience using a similar device. For example, a similar PDA or “musicphone”.

Screen

The phone's screen can be simple or touchscreen. The touch screen responds to touches on it. At the same time, it is a control element. The telephone may be designed so that the only control element is touch screen. This is exactly how the well-known iPhone works. However, today it is still more common to find phones with auxiliary control elements - buttons. However, it is likely that push-button devices will be replaced by touch ones.

An important concept is screen resolution. Resolution is the number of pixels along the horizontal and vertical axes. Pixel is the smallest element (dot, grain) that is capable of displaying colors. The higher the resolution, the better. The image will be more detailed and will not appear grainy. The screen resolution of the iPhone mentioned above is 480x320. For most Nokia phones, Samsung, etc. it is 240x320.

Screen size also plays an important role. Working with a phone that has a fairly large screen is quite pleasant. It is convenient to watch photos and videos on such devices. Large screens are typical for smartphones and PDAs. In sunny weather, however, the touch screens of PDAs have a lot of glare. They say they will “go blind.” In this case, managing the device becomes very problematic. The problem is partially solved by special protective anti-reflective films. They are glued directly to the device screen.

Conclusion

I hope that this article helped you understand the basic capabilities of modern mobile phones. I would like to believe that now choosing a device will be much easier for you. Which of the functions discussed above are really important is up to you to decide. The more functions the device has, the more it will cost. You have to pay for functionality. Whether you will use what you give your money for - time will tell. Therefore, approach your choice of phone carefully and reasonably. Follow the principle of a good tailor: “measure twice, cut once” (or in this case, it would be more accurate to say, buy). Before purchasing, consult with your family, friends, and the seller. Feel free to ask even the stupidest questions in your opinion! It's not a shame not to know, it's a shame not to ask. Think carefully about your future purchase.

Happy and thoughtful shopping!

"Watson, Bell says! If you can hear me, then go to the window and wave your hat." This phrase, spoken 141 years ago, on March 10, 1876, was the first to be uttered over the telephone. The speaker - Alexander Graham Bell - became known throughout the world as the inventor of the device.

According to statistics, Russian residents alone now make 144 million calls a day. And the average person makes almost one and a half thousand phone calls in one year.

Phone of discord

In fact, the history of the invention of the telephone is not so simple. In the early 1850s, New Yorker Antonio Meucci discovers that electricity supposedly has a positive effect on people's health. He designs a generator and opens a private practice. One day, Meucci connected the wires to the patient’s lips, and he moved to a remote room where the generator was located. When the doctor turned on the device, he heard the patient’s scream as clearly as if he was standing next to him.

Meucci gave up medicine and began experimenting with the device. By the early 1870s, he had already created drawings of a device that he called a telectrophon. In 1871, the Italian was going to register his invention, but he did not succeed.

According to one version, poor Meucci did not have enough $250 to pay the fee at the Patent Office. According to another, the papers sent by mail were lost somewhere. The third version says that the documents were stolen by order of the Western Union company, for which, by the way, that same Alexander Bell worked. Another competitor to the "well-known" inventor telephone communication there was a man named Elisha Gray. He filed the application with the Patent Office two hours later than Bell - the legal battle between the two innovators subsequently dragged on until 1893. The American Themis ultimately rendered a verdict in favor of Bell.

In the very first telephone there was no bell - it was later invented by Bell's assistant, the same Thomas John Watson. The microphone was modified by Thomas Edison. He came up with the idea of starting a conversation with the word “hello”, that is, hello (“hello” in English). However, Italians and Japanese answer calls differently: residents of the Apennines say “pronto” (“ready, I accept”), and citizens of the Land of the Rising Sun say “moshi-moshi” (“talk-talk”).

The history of this invention was not without Russians. In 1895, Mikhail Freidenberg proposed to the world the concept of automatic telephone exchanges (ATS), which connected subscribers to each other without the help of a female operator. The offer turned out to be unclaimed, the profession survived - and became a thing of the past much later, in the middle of the 20th century.

"Hello, young lady!"

Telephonization was rapidly spreading throughout the world. The first city where devices began to appear in the apartments of wealthy people was Boston, where Bell lived and worked. In 1879, the invention “crossed” the Atlantic: a telephone exchange appeared in Paris, and in 1881 it became possible to talk to a friend without meeting him in Moscow, St. Petersburg, Odessa, Berlin, Riga and Warsaw. By the beginning of the 20th century, international and long-distance lines began to entangle the planet, and by 1910 there were already more than 10 thousand stations all over the world that served more than 10 million subscribers!

A telephone in those days consisted of several devices weighing more than 8 kilograms! The Bell apparatus itself looked like an iron box with a lever and one or two tubes. In the first case, there was only a speaker in the handset, and you had to bend over to talk; in the second, the microphone was installed in an additional horn. This device was accompanied by a signal board that would ring as soon as the telephone operator called a subscriber. To use the device, you had to pick up the phone, twist the lever, which gave a current and “informed” the typist at the station that it was time to start a conversation. This is what a typical dialogue looked like:

To call a subscriber, the “young lady” plugged the plug into the corresponding socket on the panel in front of her. A good telephone operator managed to connect subscribers in less than 8 seconds.
In 1882, three-digit numbering was used in Moscow, with only 26 first subscribers. Over the next 10 years, the network grew to 1,892 numbers. The numbering became four-digit. Owning a telephone in those years was very expensive. Payment for a month of use is 250 rubles. For comparison: the monthly salary of a teacher is 25 rubles, a paramedic is 55. For the cost of installing a telephone, you could buy a full set of clothes or, for example, two excellent horses.
With the beginning of the 20th century, the Swedes began to deal with telephones in Moscow - the Ericsson company. They presented new model device: the handset took on the usual appearance with two holes, and instead of a lever, a regular button appeared, or rather two - for connecting and for hanging up. The Scandinavians were able to reduce tariffs - a month of owning the device began to cost 63 rubles.
In 1903, a telephone was installed in the Kremlin. Emperor Nicholas II, who came to Moscow for this occasion, was presented with an ivory telephone inlaid with gold.

Telephony throughout the country

On January 1, 1917, there were 232 thousand in Russia subscriber numbers, the numbering became five-digit. During the revolution, Lenin ordered his supporters to first seize the post office, telegraph office and telephone exchange. After the Bolshevik victory - already in 1919 - communications were nationalized. Private telephones were also confiscated - they were transferred to police stations, military commandant's offices, institutions and enterprises of the city. Communication has become a rarity, available only to the party nomenklatura and the heroes of the Red Army, as well as doctors.
The pre-revolutionary volume of subscribers was restored only by 1923, and through the efforts of the same Swedes from Ericsson, as well as the Germans from Siemens. At the same time, the construction of automatic telephone exchanges began, which did not require the work of telephone operators. The first station in the USSR appeared in 1926 in Rostov-on-Don.

One of the reasons for replacing human labor with a “soulless machine” was secrecy - in an environment of constant spy mania, allowing “young ladies” to wiretap telephone conversations would be unforgivably irresponsible. However, the profession of a “telephone girl” for internal communications finally became a thing of the past in the forties.
The advent of automatic telephone exchanges led to a change in the appearance of the devices themselves - they now had a dial dial. One of the first such devices was installed, of course, in the Kremlin - it received the nickname “spinner”. This word is still used today to refer to a government telephone.

On the disk, in addition to numbers, there were also letters of the Russian alphabet - A, B, V, G, D, E, ZH, I, K and L. The letter "Z" was absent, since it visually resembled a three. The numbers themselves were in format A-21-35.
In the USA, alphabetic numbering is still used today. Even on the first American telephones, there were rows of letters next to each number. If you have a push-button landline phone, pay attention - they are still written there. Even the on-screen keyboards of mobile phones still have letters - and they are not intended for typing SMS at all. This was done to make it easier to remember numbers, for example, instead of the long and complex number +1-888-237-82-89, the combination 1-888-BEST BUY is used.
In Russia, this tradition did not take root due to the similarity of the pronunciation of Russian letters. Until the mid-1960s, telephone numbers in the USSR contained both numbers and letters, and then the latter were abandoned.

Officially, the first conversation on a mobile phone took place in 1973 in New York. But there is a version that the world’s first wireless devices appeared not in the USA, but in the Soviet Union. Back in 1961, TASS reported that radio engineer Leonid Kupriyanovich developed a model of a telephone that could transmit voice via radio to base station, located no further than 25 kilometers. The device weighed 500 grams and could operate in standby mode for 20–30 hours. It looked like a box with a number plate, a pair of toggle switches and a plug-in tube. The owner of such a device had to either hold the case in one hand and the tube in the other, or hang the box on his belt.

The author of the invention writes in the magazine “Young Technician”: “Wherever you are, you can always be found by phone, you just have to dial the known number of your radiophone from any landline phone (even from a pay phone). call, and you start a conversation. If necessary, you can dial any city telephone number directly from a tram, trolleybus, or bus, call an ambulance, fire truck or emergency vehicle, or contact home..."
Alas, after 1965 no one wrote about this invention anymore, and Leonid Kupriyanovich himself began to develop medical equipment.
Another thing is the Altai apparatus. This system of full-fledged mobile communications was deployed in Russia in the early seventies. But the phones themselves bore little resemblance to the cell phones we are used to: a large box - about 5-7 kilograms - with a handset. Carrying this in one’s hands was problematic, but the devices were equipped in the cars of the special services and party nomenklatura. The era of “Altai” ended in the 21st century, in 2011.

Mobile for the price of a Mustang

On a clear day on April 3, 1973, an elderly man named Martin Cooper left his office. Motorola in Lower Manhattan (New York). In his hand he was holding a strange light beige object. Moving away from the building, he pressed some buttons on it.
Almost immediately, a bell rang at the headquarters of the competing company Bell Laboratories - the machine in the office of the head of the research department, Joel Engel, was ringing. Picking up the phone, he heard Cooper's voice: “Do you know where I'm calling you from? I'm calling you from Manhattan, from the world's first cell phone.” In his memoirs, the researcher could not give Engel’s answer, but said: he clearly heard him grinding his teeth.
It took 10 years to fine-tune the device - the Motorola DynaTAC 8000X appeared on the public market only in 1983. The device weighed about a kilogram and was 25 centimeters high. In talk mode it worked for 35 minutes, and charged for 10 hours. The price was astronomical - more than $3,500, but despite this, a queue of buyers lined up for the phone. For comparison: for $6,500 in the USA you could buy a brand new Ford Mustang.
Full-fledged to Russia cellular in the form in which we know it came in 1991. Data transmission was carried out via the Nordic Mobile Telephony (NMT) standard, and the most popular phones were Finnish Nokia. According to their own technical specifications they lost to the Motorolas - they weighed about 3 kilograms. The price was also steep - with connection, the device cost $4,000, and a minute of conversation cost $1.
By this time, the Motorola MicroTAC 9800X had already been released overseas - a phone with a flip cover that fit in the palm of your hand.

GSM AGE
By 1993, there were four mobile communication standards in operation in Russia: NMT (Delta Telecom operator), D-AMPS (BeeLine, which was then written in Latin letters), the already mentioned Altai and GSM (MTS and a little later Severo -Western GSM"). The last one has won - so far Voice connection transmitted exactly in this format.
At this time, in the UK, 22-year-old Sema Group employee Neil Papworth was testing the capabilities of the GSM standard. Engineers were already able to implement the ability to determine the calling line number and a service that allowed this function to be blocked. But in his free time, Papworth was engaged in other work - he was trying to achieve the ability to transmit not only voice, but also text over mobile lines. And in December 1992, he succeeded: the world's first SMS (Short Message Service) was sent. The text is simple and straightforward: “Merry Christmas!” The inventor was sure that his brainchild would be used exclusively for sending service messages, but it turned out differently: in 2015, 20 thousand text messages were sent around the world every second.
Telephone sets at this moment began to decrease in size. Displays, on the contrary, grew. If the first Motorola had only one line on the screen, then the Nokia 2110 released in 1994 already had three. This device has become somewhat iconic - it has an integrated alarm clock, calculator, stopwatch and SMS function. When making a call, that phone emitted the now famous Nokia Tune melody, which was installed in standard package for all devices of the Finnish company.
This phone turned out to be very popular in Russia - and even earned the reputation of “a mobile phone for the new Russian.”

Almost all the functions we are familiar with appeared in phones at the turn of the century. In 1999, devices learned to access the Internet using the WAP protocol. At the same time, web developers began to create mobile versions- no pictures. In the same year, a phone appeared that used two SIM cards. True, switching between them had to be done manually. In 2000, cell phones played MP3 tunes, took photographs, and even picked up GPS satellite signals. In 2002, Siemens released the SL45 with Java technology. It was possible to download third-party applications on this phone. Mostly games, but also melodies.
The design of telephones tended towards miniature - some models were created as ladies' ones. As a result, such “babies” as the Samsung SGH-A400 or Panasonic GD55 appeared - the size of a matchbox. Moreover, both of these models easily accessed the Internet, even if they only had a monochrome screen.
The world's first smartphone is considered to be the Nokia 9210, announced in 2002. It was running the rare operating system (OS) Series S80. Subsequently, it, as well as other OS from Nokia S40 and S60, became part of the common Symbian OS, which was installed on their products not only by the Finns, but also by Motorola, SonyEricsson, Siemens, Panasonic, Fujitsu, Samsung, Sony, Sharp and Sanyo. The presence of an operating system made it possible to create a more convenient interface and work in multitasking mode.

In January 2007, Steve Jobs revealed iPhone world. Apple's smartphone was not the first device with a touchscreen function (that is, it could be controlled by touching the screen with your fingers), and certainly not the first touch phone. But this model, due to its wild popularity, made smartphones the way we know them now: a large screen and a minimum of buttons. The device with the apple on the rear panel now has an alternative operating system - iOS. A year later, a third player will appear, which now occupies almost 80% of the market - Android OS.
The latest revolutionary change was the scheme wireless charging battery It appeared back in 2009, but gained popularity only in 2015. Another innovation is the AppStore and GooglePlay application stores, which emerged in 2010. You can also add NFC technology here, which allows you to pay by touching your phone to the terminal.
All other characteristics of phones have evolved. Let's take built-in cameras as an example - the first of them had a resolution of 0.3 megapixels, and now you can find devices with 41 megapixels on the market. The latest trend is the double flash. The Internet has also accelerated - if on the first phones with WAP downloading occurred at a speed of 10 kilobits per second, now, with LTE technology, it is already measured in gigabits.
The design, in turn, has been simplified: after the riot of form factors of the 2000s, now the vast majority of models are the usual rectangle with a thin body. After miniaturization, phones began to grow again - up to a seven-inch screen diagonal!

Experts interviewed by TASS argue that in the coming years smartphones are unlikely to change their appearance, but have every chance of squeezing laptops and cameras out of the market.
Leading analyst of Mobile Research Group Eldar Murtazin believes that phones will turn into full-fledged laptop computers, to which you can connect an external monitor, keyboard and mouse. They will have a large amount of RAM (there are already eight-core processors with more than 4 GB of RAM). With the advent of the 5G standard (data transfer at speeds of up to 7 Gb/sec), people will begin to abandon Wi-Fi.
Murtazin believes that people’s “dependence” on phones will also increase. Will become a thing of the past bank cards and magnetic badges: they will be installed directly into the phone (such technologies already exist). Perhaps the YotaPhone experiment with two screens will be repeated: “Everything else, for example flexible displays, is exotic, and they are unlikely to be on the market en masse.”

Today, there are a huge variety of different phone models, and when the question arises of how to choose a phone, many are simply lost.

Yes, in online stores you can select a gadget by parameters; there are even sites that take data from several stores and compare characteristics and prices.

But due to such an abundance of models, the average person simply cannot understand which mobile phone is better and experiences real agony of choice.

To reduce them, below we will look at the criteria by which phones are usually selected. After this, everyone will be able to understand what they need and make the right choice.

Criterion No. 1. Budget

Whatever one may say, it always comes down to the amount of money that we can spend on buying a mobile phone.

Tip #1: Even before purchasing a new gadget, you should determine how much money you are willing to spend. After this it will become clear what to expect.

In general, all phones can be divided into the following categories:

And if you need a phone specifically for this, then choose from models that cost up to 1000 rubles.

And the only characteristic that should take place when choosing a dialer is the quality of communication.

This refers to how clearly the interlocutor’s voice is conveyed. And here phones from Fly especially stand out.

An example of a good dialer is the Fly DS105C, which can be bought for 800 rubles. If you describe it in two words, they would be the words “affordable” and “simple”.

Indeed, it will be very difficult to find a mobile device that is easier to use.

It has a 900 mAh battery, which is enough for several days of operation without charging (276 hours in standby mode).

Its dimensions are only 110x45x14.6 mm - it fits very easily in your hand. There is a radio, an audio player and even a video player in mp4 and 3gp format.

In general, an ideal choice for those who have very little money in their pockets and who need the phone purely for calls.

But this is the 21st century, after all, and if you’re going to buy a phone, you can save up and buy something more interesting. Then you need to pay attention to all the criteria below.

Criterion No. 2. OS (operating system)

Every modern phone has an operating system.

The most popular of them are:

Symbian. This OS today belongs to Nokia and, accordingly, is used only on devices from this company. Now it is not nearly as popular as it was 4-7 years ago. And it is being replaced by the following systems on our list.
Android. Most modern phones run on Android. The OS is constantly updated and improved, but it is often buggy and does not work the way the user wants.
At least this is evidenced by reviews on the Internet left even in 2016. On the other hand, this system is the most popular, it is used by Samsung, HTC, Motorola and all Chinese phones, which is why they talk about it the most.
Apple iOS. A system designed specifically for Apple phones. There is nothing to discuss here - buy an Apple phone, get iOS.
Blackberry OS. Like iOS, it is designed only for Blackberry phones. This system is the record holder on this list, as it was created back in 1999.
Windows Phone. The developers tried to make Windows analog 10 for computers with the same multi-colored icons of various shortcuts in the form of squares, only for smartphones. Very popular in the West.

Yes, there are many more different operating systems, for example, OS Bada, Palm OS, Open WebOS, Maemo and others. But it’s better to choose from these five.

And the reason for this is that they are simply supported in our area, that is, if a phone on the same Android breaks down, we will fix it, but with a phone on OS Bada it will be much more difficult to figure out.

You will need to look for a master who understands this issue, and this is very difficult.

So, the operating systems are defined. Now all that remains is to understand what OS you want for your cell phone.

You should select an operating system according to the following criteria:

The purpose of a smartphone. If a business person needs it, who constantly works with documents and wants to customize the interface for himself, then Windows Phone is suitable for him, and if for games and all sorts of “bells and whistles,” then definitely Android.
If reliability is a priority, that is, a person does not care about games, but he wants to get a phone that nothing will happen to (for example, viruses will not attack), then this is Blackberry OS.
Budget. If you don’t have a lot of money in your pocket, but want to get a good gadget, then choose Symbian. This OS is aimed at the budget class. But if money is not a problem, then you can spend money on Apple with Apple iOS.
Android phones are a kind of golden mean.

Tip #2: It's best to look awayAndroid, because today most applications are written specifically for this OS. In addition, phones withAndroidare cheaper thaniPhone, but have almost the same functionality. And, after all, this is the most popular OS in our area.

Criterion No. 3. Phone power

How powerful a phone is can be determined by the characteristics of the phone's processor and RAM.

CPU

This characteristic is related to the power of the mobile phone. The power of a processor is determined by its frequency. It is measured in Hertz (Hz). It is logical that the more there are, the better.

Today, the normal rate for phones is 1-2 GHz (GigaHertz).

In addition, the power of the processor depends on the number of cores, each of which has its own specific number of Hz.

Interestingly, even on the most powerful modern smartphones, the number of GHz frequencies rarely exceeds 2.5 GHz.

The only ones that stand out are the Chinese masters, who manage to fit up to 3.5 GHz into a regular phone. An example of such a phone is the ZTE Nubia Z9.

Looking at the most expensive models and phones from the budget category, you can notice one interesting feature.

It lies in the fact that the processor power is budget smartphones often more than the most expensive ones.

This is quite logical, because manufacturers simply do not yet know a way to make the processor more powerful.

Therefore, if it is important for you that the phone is powerful, you don’t have to overpay.

An example of a truly powerful device is Xiaomi Redmi Note 3 at 2 GHz in the processor. It costs about 230 dollars.

For comparison: Samsung Galaxy The S7 costs about $830 and has a 2.3GHz frequency. Xiaomi also has 32 GB of internal memory, GPS, GLONASS and many other useful functions.

The only drawbacks of the phone are the poor camera, dull display (we'll talk about this later) and non-removable battery– if it breaks, you cannot replace it on your own, and this is an additional inconvenience.

But Xiaomi Redmi Note 3 is one of the most powerful phones today due to the following characteristic - RAM.

RAM

Another characteristic that affects power.

Measured in Gigabytes (GB). The number of GB determines how quickly the system can respond to user actions and process various operations.

So, in Xiaomi Redmi Note 3 there are as many as 3 of these Gigabytes. In the same Samsung Galaxy S7 there are already 4 of them, but it also costs an order of magnitude more, as mentioned above.

There is no point in choosing a phone depending on the RAM, because with a powerful processor, no one will ever put little RAM into a phone, otherwise the device will not be able to work correctly.

The bigger, the better.

Clue: To understand how much powerful processor, exists convenient program entitledAnTuTu Benchmark.

In this program, each phone is given a score based on its performance.

So, at the beginning of March 2016, a study was conducted that showed that the most powerful phones have a processor called Qualcomm Snapdragon 820.

In second place is the Apple A9 (for iPhone only), and in third place is Samsung Exynos 8890.

Huawei Kirin 950;
Samsung Exynos 7420;
Qualcomm Snapdragon 810;
Qualcomm Snapdragon 652;
Apple A8.

Based on this, we can formulate the following advice.

Tip #3: For a phone to be powerful, it must have one of the processors listed above.

But the problem is that such processors are not installed on budget smartphones.

Therefore, here is a tip for those who are looking towards budget devices: Qualcomm Snapdragon 615, Mediatek MT6795 (aka Helio X10) and Qualcomm Snapdragon 801 also perform well.

An example of a phone with the most powerful Qualcomm Snapdragon 820 processor to date is the OnePlus 3 with 4GB RAM.

The cost of such pleasure is 500-600 dollars (the model has not yet been released).

Tip #4: When choosing a phone, look at how much it dials in the programAnTuTu Benchmark(this information can be easily found on the Internet). This will give you the opportunity to really see how powerful a particular model is.

Criterion No. 4. Working hours

How long a device can operate depends directly on the battery. Battery capacity is measured in milliamps. Of course, the more there are, the better.

Approximately, phones with 2 GB RAM and a 2 GHz processor frequency should have at least 3000 mAh.

This will give the device the ability to work for about two days with a small number of games, a lot of Internet use and work with documents.

If you continuously play some heavy games, for example, GTA or Nova 3, then a device with 3000 mAh will last about 6 hours.

But even the most powerful phones rarely have more than 4000 mAh. Yes, there are some “unusual” models with 5000 mAh, but they don’t last long.

This is very clearly seen in the example of the Bravis Power phone. The phone has 4500 mAh, but there is practically no power and, judging by reviews on the Internet, the phone lasts about 4-5 months.

It costs $115. The combination of this price and this battery capacity raises many questions. And for good reason.

From the above, we can conclude the following: if the phone costs less than $150, and its battery capacity is more than 3000 mAh.

This is very strange and such a device is unlikely to work for more than a year.

On the other hand, manufacturers often try to save on this parameter and try to use the processor, RAM and other parameters.

Yes, on budget phones A capacity of approximately 2000 mAh is allowed. After all, all other elements there do not consume so much energy.

Therefore, we can derive a certain golden parameter.

Tip #5: The battery capacity should be from 2000 mAh to 4000 mAh.

Criterion No. 5. Built-in memory

This setting determines how much data will fit on the phone.

Typically, manufacturers try to put no more than 16 GB on budget phones; more expensive phones can have either 32 GB or 64 GB.

But, looking at this parameter, you need to take into account only one condition - is it possible to use a memory card.

If you can insert an additional card, then a small amount of built-in memory is not a problem.

But it happens that this is not possible, and then it is the built-in memory that will play the main role.

True, there is still the possibility of using cloud storage, but then you will be tied to the Internet - if it is not there, then you will not see your files.

Therefore, it is ideal that the phone has about 8 GB of internal memory and the ability to insert a memory card.

There is one more thing worth saying about the memory card. Often manufacturers make the phone in such a way that it can accept SD cards of 200 GB - 1 TB.

The fact is that if the phone has too many files, about 100 GB, it will slow down and something will have to be deleted.

After all, even the most powerful processor and a large amount of RAM will not be enough to process such an amount of information.

Accordingly, there is simply no point in having memory cards that are too capacious.

Tip #6: Choose phones with the ability to insert a memory card up to 100 GB.

Criterion No. 6. Camera

It’s very easy to check how high-quality and clear a photo is on a particular phone.

To do this, you need to photograph something and enlarge some part of the picture as much as possible, that is, use the zoom function.

If the enlarged part of the picture is blurry and unclear, this means that the camera on the phone is not of very high quality.

But sometimes there is no way to pick up the phone and “taste it.”

Then you need to look at two characteristics - the number of megapixels and the aperture.

Today, almost all phone and camera manufacturers are trying to attract people with the number of megapixels.

This value reflects how many pixels form the image. But this characteristic is not the only one that affects the quality of the picture.

The size of the aperture or relative aperture also affects. The meaning of this value can be explained with an example.

Imagine that you are in the country, it is raining and you need to collect as much water as possible in some containers.

If you place an ordinary mug with a diameter of 15 cm, then not many drops will fall into it, and the water will collect slowly.

But if you place a large bowl with a diameter of 50 cm, more drops will fall into it and the container will fill much faster.

In the same way, the aperture reflects how much light enters the camera lens.

The aperture size is designated as “f/size”. In the figure you can see the sizes of different apertures.

It becomes clear that the smaller this number, the larger the aperture; accordingly, the more light it can capture and the better quality the pictures will be.

Megapixels + aperture

It’s interesting that there’s a lot written on the Internet now that nothing at all depends on the number of megapixels and that only the aperture affects the quality of pictures.

In fact, this is not entirely true, because there have been cases when developers, using this myth, put few megapixels on phones and made the aperture large, and as a result, the pictures were not of very high quality.

Therefore, it is better to choose phones with a minimum “f/” value and a maximum number of megapixels.

On the other hand, it is very rare to find a phone with a large number of megapixels and a large “f/” value; manufacturers combine these parameters.

According to these parameters, cameras from Samsung perform very well. In general, this company has many of its own technologies, one of which concerns cameras.

The favorite in this regard is the Samsung Galaxy S6 with a 16 MP main camera and a 5 MP front camera.

To visualize this, here's a shot of a night landscape taken with an iPhone 6.

And here is a photo of the same area taken on a Samsung Galaxy S6.

Agree that the photo taken on the Samsung Galaxy S6 is brighter and more saturated. After all, it has more resolution, which allows you to see the smallest details on the picture.

Tip #7: When choosing a camera on your phone, focus on the combination of megapixels and aperture.

At the same time, you should not pay attention to only one of these parameters, because often manufacturers, trying to deceive their customers, write only the number of megapixels or only the aperture (usually the first).

Criterion No. 7. Screen

Everyone wants the picture on their phone to be bright and rich. But what should you look for to choose such a phone? Brightness and saturation depend on four parameters:

Diagonal.
Permission.
Pixel density.

Let's look at each of them in more detail.

Diagonal

This characteristic reflects the distance from one corner of the screen to the opposite one. The figure below clearly shows this distance.

The screen diagonal should be chosen depending on why the phone is needed:

for calls and basic functions – 3-4 inches;
for Internet surfing and reading books - 4-5 inches;
for games and watching movies - 5-6 inches.

Everything is very simple here.

Permission

Screen resolution is directly related to diagonal in the following ratio:

for a diagonal of 3-4 inches, the resolution can be 480x800;
for a 4-5 inch diagonal, the resolution can be 960x540;
for everything else, the resolution can be 1280x720 (HD), 1920x1080 (FullHD) and 2560x1440 (QuadHD).

Of course, the higher the resolution, the clearer the picture will be.

Pixel Density

It is written as PPI (pixels per inch) and expresses how many pixels fit in one inch of the screen. It is clear that the higher this characteristic, the clearer the image should be.

Typically, manufacturers try to make the number of pixels per inch corresponding to the screen resolution.

So, on screens with a resolution of 1280x720 there can be up to 300 ppi. In principle, there is no point in choosing a phone depending on this characteristic.

You need to look at the previous two parameters - diagonal and resolution. In addition, the following parameter is very important.

Screen type

Today the most popular types of screens are the following:

OLED;
AMOLED and Super AMOLED;
AFFS.

In our area you are unlikely to see phones with the last two types of screens, but in the West they are very popular.

It is very interesting that of the first three types, models with Super AMOLED screens perform best.

A phone with HD resolution and a Super AMOLED screen will look much better than a model with FullHD resolution and an IPS screen.

In particular, viewing angles will be much better.

This option means that you can look at the phone from almost a right angle and still be able to see what is happening on the screen.

In the figure you can clearly see a comparison of these two types.

This is especially true for Samsung phones, which use a lot of their own unique technologies, so Samsung with Super AMOLED is much better than any other phone with Super AMOLED.

However, other screens also look quite good, and you should pay attention to this characteristic only if you really care about the saturation and clarity of the screen.

Tip #8: If saturation and brightness are important to you, choose a phone withSuper AMOLEDscreen.

Here is another photo that confirms that it is best to choose Super AMOLED screens.

The leftmost phone is here Sony Xperia Z Ultra with TRILUMINOS screen, the second is Samsung Galaxy Note 3 with Super AMOLED, then comes Sony Xperia Z1 with the same TRILUMINOS and the last one is Lg G2 with IPS.

It is clearly visible that Samsung looks better than the rest.

Criterion No. 8. Phone brand

As for which brand of phone to choose, the following points will help:

If it is important to you that your phone can be repaired in our area, then these are Samsung, Lenovo, Fly, Prestigio, Asus, Philips, Sony, Lg. The fact is that in the CIS countries there are certified centers that carry out repairs.
The rest of the phones will need to be sent for repair, most likely to China, which means you'll have to pay about $150 for shipping. It turns out that the guarantee makes no sense.
You can, of course, find a local craftsman, but then no one is responsible for the quality.
If performance is important, then Xiaomi, Meizu, ZTE, Sony and the vast majority of other Chinese brands. In principle, Samsung performs well, but it costs more.
If important good camera, then Samsung, Sony, Apple, Lg, HTC, Lumia and some Lenovo models.
If ease of use is important, then all phones are operating system Android.
If operating time is important, then DEXP, Fly, Philips, Highscreen, Lenovo and Samsung.
If reliability is important (so that the phone does not break), then Sony, Samsung, Lg. Everything else most often fails after a year of use. Yes, if there are exceptions among the same Samsungs, but basically, all models work for at least 5 years.
If you don’t want to spend a lot (“I want something inexpensive, but good”), then Xiaomi, Meizu and other Chinese brands.
If you want to show that you have a lot of money, iPhone. The fact is that these phones do not have any special characteristics, but are expensive due to advertising. Therefore, you should buy an iPhone only in cases where you just want to spend money.

In general, when choosing a brand, you need to focus on what is important to each specific consumer.

Criterion No. 9. Protective characteristics

I really want the phone not to break, to withstand falling into water and other emergency situations.

Of course, you can cover the phone with cases, protective films, and generally wrap it in film and carry it in a velvet container, but you want the phone itself to be able to withstand at least a fall to the ground.

Finding a smartphone with a high degree of security is very simple - usually the characteristics say “IP...”, for example, “IP67”. This means the level of protection.

By the way, the most secure phones have a protection rating of IP67. Therefore, if you plan to drop your gadget often, it must have “IP67” on it.

An example of such a device is the Samsung Galaxy xCover S5690, which can withstand being in water, being buried in the ground, and can even withstand being run over by a car!

Tip #9: If the durability of your phone is important to you, choose devices with IP67 protection level.

But even without this level of protection, a mobile phone can still be reliable if it has a special protective Gorilla Glass.

This glass has a high degree of resistance to scratches and impacts.

With such glass you will not need any additional protection.

Of course, if the phone is run over by a car, the screen will still crack, but it will withstand a fall on an asphalt road calmly.

But even if the phone does not initially have such protective glass, you can always buy additional glass.

But here it is important not to make a mistake and not buy ordinary film; you need to choose glass!

Tip #10: Choose a phone with protective Gorilla glass Glass or immediately buy additional glass along with the phone.

In addition, when choosing a reliable phone, it is important to look at the case material.

It is best, of course, to buy devices with a metal body. But good plastic in a high-quality protective case will also withstand a hit to the ground.

Results

If you want to hear an expert’s opinion on what phones you can buy this year, then experts agree that the most interesting models in terms of all characteristics will be the following:

Samsung S7- 4 GB of RAM, 2.3 GHz processor frequency, 32 or 64 GB of internal memory, 12 MP camera and 3000/3600 mAh and, most importantly, a curved display.
In principle, the popularity of the phone will be due to its unusual display. But all other characteristics are pleasing. This pleasure costs about $900.

Xiaomi Redmi Note 3 And Samsung Galaxy J7. The undoubted leaders of phones in the budget category (up to $300). Both have a diagonal of 5.5 inches and 16 GB of internal memory. Samsung has a 13 megapixel camera, but it takes better pictures than Xiaomi.
Random access memory Xiaomi has 2 GB, Samsung has 1.5 GB. In AnTuTu, the first one gains about 50,000 marks, and the second - 41,000. Samsung wins due to better display. If performance is important to you, choose Xiaomi.

Sony Xperia Z5. 5.1-5.9 inches screen (depending on version), 28 megapixel main camera, 4200 mAh and resistance to immersion in water - all in the best traditions of Sony. The cost is about 800 dollars.

How to choose a phone - Main selection criteria

For my birthday, my parents gave me a new beautiful mobile phone. It is very modern, stylish and has all the features I need. The mobile phone has a large touch screen, and it also has a lot of different pictures and melodies. I'm delighted with the eight megapixel camera with built-in flash. I can also send text and multimedia messages. The phone has such functions as: bluetooth, Wi-Fi internet. The phone has a powerful processor, thanks to which I can play various interesting games in my free time. I download games for free, thanks software"Android". The phone came with headphones so I can listen to the music I downloaded or the radio. My new phone can easily replace a laptop or tablet, since you can install programs for printing text documents, dictionaries, reference books and translators on it. He is everything to me: a means of communication, a toy and a study assistant. I am very grateful to my parents for such a gift.

Essay: mobile phone - luxury or necessity.

Not a day goes by, there is not a place where we cannot hear the familiar tonal melodies, the source of which is a mobile phone. A mobile phone today can fit in a small pocket. Just a few years ago, the owner of a mobile phone felt interested and envious glances at himself, because at the beginning of the new century only well-off people could afford a mobile phone, and now even small children have them.

However, even today, when everyone has two or even more mobile phones, you can also distinguish yourself from the crowd by purchasing a fashionable, very expensive phone, the cost of which is sometimes equal to the cost of the most modern personal computer. But is a phone worth this money, which, due to its price, turns from an everyday necessity into a real luxury?

If you look at this from one side, then even today a mobile phone can be an indicator of the level of financial condition of its owner. Now almost everyone can determine at first glance how expensive the phone is in their hands. Expensive phones incorporate the latest developments and have a prestigious appearance. Therefore, the buyer pays money not only for functionality, but also for design, quality and warranty. They are most popular among representatives of the modern business world and young people.

But inexpensive phones are in great demand among practical people, who first of all need to make calls and receive calls from others. They don't care about color, weight or size doesn't matter much.

If we look at the problem from the other side, it is well known that people very quickly get used to the conveniences that include mobile phones. Moreover, the offers of phone manufacturers and mobile operators are becoming more and more attractive... After all, having bought a phone or smartphone for the first time , you are unlikely to want to part with him. By purchasing inexpensive phone, after a year you will want to change it to a more advanced one.

In general, a person chooses this or that phone based on financial capabilities, personal tastes, and how wide his circle of contacts is. And the fact remains unchanged that the demand for phones is growing every year, and at the same time the quality of the goods offered is also growing. This indicates that a mobile phone is a necessary, convenient, reliable thing, and therefore a mobile phone is more of a necessity than a luxury.
