Telephone evolution

There are discoveries and inventions that have allowed the change in the evolution of man, such as the invention of the printing press that changed the means of communication between people at that time and undeniably allowed the dissemination of knowledge in textual form.

mobile phone evolution

In these moments of technological explosion, we have become exceptional witnesses of one of the most important inventions in the communications industry in text, data and voice, grouped in a single small device that has become an indispensable instrument for our daily lives. relationship with our fellow men.

This article shows you the evolution of mobile phones and their characteristics, which have shaped the behavior of man in the world of communication, business, information, education and their social relationship. It is paradoxical that such a small instrument has become a translator of scales in the world, if we compare that, with just a click of the mobile, we have the world at our fingertips.

Beginnings Evolution of the phone

Mobile phones at their dawn: Its main use was voice communication, originating a new era of mobility, a significant advantage if we compare it with our personal computer.

Another characteristic of great importance consists in the conversion of this device in corporal use, that is, together with our personal documents such as identity cards, passports, credit or debit cards, driver's license or personal card of our company or educational institute. , the mobile phone is considered as one more identity document.

The beginning of the mobile is conceived in the scenario of the Second World War, an event that marked the need for remote communication. The Motorola company created a device called Handie Talkie H12-16, its function consisted of the use of radio waves in a frequency band below 600 KHz.

Its purpose was only a means of military communication. In reality, this equipment was not very mobile due to its great weight and size, and its use was limited to military vehicles. Its technical characteristics were analog in nature, with HF and VHF bands, administered by the American company Bell.

For its part, Ericsson marketed the Mobile Telephone System (MTS), administered by Bell, its characteristics: Great weight and its use was in automobiles. The year was 1955.

Next, a Walkie-Talkie weighing 1,2 kilograms capable of connecting at 1,5 KHz is built. Its design is attributed to the Russian inventor Leonid Ivánovich Kupriyanovich in 1955. Some time later an improved version was made, with a smaller size and less weight and extending its range of 2 km, in the year 1957.

First commercial mobile phones Evolution of the telephone

The beginning in this sector is attributed to the episode that occurred on April 3, 1973, when Martin Cooper, director of Motorola, called his rival in the sector, Joel Engel of Bell Labs of AT&T. It was the first call made wirelessly.

Motorola Dynatac Phone Evolution

Said call was made through Motorola Dinatac 8000x (Dynamic Adaptive Total Area Coverage), it was the prototype used by Cooper, it had the following dimensions: 33 x 4,5 x 8,9 centimeters and weighed 800 grams, it had a numeric keyboard (keypad) phone, had nine special keys.

The autonomy of this equipment was only one hour in conversation (eight on standby) and its cost was 4.000 dollars at the time. Its main feature was its storage capacity, it could save 30 phone numbers in its address book. Battery life was 1 hour. Its performance standard was very good in reception and transmission.

Motorola MicroCT.

Now let's see the launch of this team. It was a reduced version in size, weight and had better autonomy. Its first versions consisted of analog phones before the arrival of the GSM system. The biggest innovation was that the speaker folded over the keyboard.

 Motorola Startac

This prototype was launched in 1996, it is considered the first phone that gave great importance to design, sacrificing certain qualities of functionality, perhaps because of this attribute it was for the date, a popular mobile and accessible to carry due to its low weight.

XNUMXth century Evolution of the mobile phone

The 90's were dominated by manufacturers Motorola and Nokia, becoming a true technological struggle. Among the dominant prototypes we have:

Motorola 2900 Bag Phone

Nokia continues to flood the market. In 1999, he presented this new mobile, very versatile for the time. It did not have an external antenna, causing it to present reception problems. It contained special software dedicated to games, interchangeable covers and different personalized ring tones. It was a very popular mobile among users due to its low price.

Evolution of the telephone in the SXXI

The Nokia firm is consolidated as the world's leading mobile producer, its prototypes had special features such as: Mobile Internet access, availability of WAP connections.

Next, we detail the main mobiles of the present century, with their characteristics. Every day more innovative:

BlackBerry

In this period, the BlackBerry arrived, very popular in the population of the professional sector. The phenomenal RIM BlackBerry 5810 entered the market in 2002. It was the first smartphone, due to its integration of mobile data support and SMS text messages and push email, which became popular as a positive attribute of this smartphone. technology. In addition, it had a highly versatile QWERTY keyboard.

Its weak point was that it had no microphone or speaker. However, to remedy this inconvenience, the use of headphones (hands-free) was planned.

Nokia 1100

Year 2003, Nokia introduces the first version of the economical, versatile phone, resistant to the inclemency of the environment. It became the most popular model.

This year 2007, Nokia continues, showing the evolution of the mobile phone. This team is considered the 'cheapest mobile phone in history'.

Its price made it an attractive device for young people from all over the world and its demands were so insistent that it sold out of the inventory of the commercial agencies of these products within a few days.

Apple iPhone smartphone

Steve Jobs, CEO of the Apple industry, presented his famous Apple iPhone smart phone to the audience in 1997.

This is the device that really revolutionized the world of cell phones in the entire world of telecommunications, becoming the cornerstone of Smartphones. It was a team that featured a 3,5-inch multi-touch screen, which covered a high percentage of the front of the mobile.

Among its main technological features we have quad-band GSM technology, backed by EDGE technology and Wi-Fi wireless connectivity.

The beginning in the United States, materialized through the giant of the telephony AT&T. Its operating system was an innovation: iPhone OS, later renamed to iOS. Its interface was conceived under the format of direct manipulation, with additions of sliders, buttons and switches forming multi-touch gestures.

In its beginnings, its weakness consisted of not having support to install more applications than those originally installed. It is important to emphasize that this condition was later remedied, becoming a true global event in the world of telecommunications.

New era Smartphone – Google Android and Samsung

Android is a Mobile Operating System, developed by the Internet giant Google, its first Smartphone was HTC Dream, in 2008.

Samsung Galaxy SII Phone Evolution

Considered by experts as the powerful mobile, due to robust hardware. The presence of multiple applications that gives you a domain in versatility and of course elegance.

Its design was conceived respecting ergonomic characteristics, such as adaptability to the palm of the hand and its visual approach with the least effort on the part of the user.

It consists of a camera considered one of the best on the market, 8 megapixels and AMOLED screen, of course with an Android Operating System, very light weight. Its appearance on the market was in 2011.

Huawei Mate 20 Pro

It consists of a Smartphone with amazing features. It has a large complex camera made up of three 40, 20 and 8 megapixel lenses, the latter two working as a wide angle and telephoto lens.

In this order of ideas, another innovation consists of the reversible charge of the own battery or of other Smartphones that are compatible with wireless charging. Its battery is 4,200 mAh, with autonomy for long hours of use and a high capacity for charging recovery in just 30 minutes.

This prototype presents as an additional function the presence of a fingerprint scanner on the screen and an innovative facial recognition system in the front camera as a security instrument to unlock the mobile quickly and safely.

At the time we write this article, the absolute dominance of Samsung mobiles with the Android Operating System prevails in the world market, turning these devices into "the new virtual office" that every businessman or entrepreneur has dreamed of having.

Generation Evolution of the phone

It is difficult to conceive of the expansion of mobile phones without standardization and modifications in terms of storage capabilities and response speed and facilitating the adaptation of changes in protocols dedicated to communications networks and support by operators.

Much progress has been made in a short time, from the use of radio wave paths with frequencies below 600 KHz, then the use of AM and FM, the Bell and Erickson services, to the mega-use of Samsung. Let's see below the evolution of the mobile phone by generation.

First generation 1G

Its main feature was the use of analog channels, with the NMT system. The Ericsson company modernized the system, operating in frequencies above 900 MHz, increasing the service for a large number of users. Starting from the NMT system, other systems with greater robustness and innovation were developed that allowed the establishment of such an important generation.

Japan was the first pioneering country in the construction of a Cellular Telephone Service Center, thus providing a marketing scheme for the nascent technology, available to satisfy the service needs of users, in 1979.

In Europe it was the Scandinavian countries (Finland) that started the route in 1981 and in the United States the commercial service is established, through the use of an AT&T network in 1983.

Second Generation 2G

It occurs in the 90's, implanting the GSM system, IS-136, iDEN and IS-95. GSm became the most relevant development, it was the technological reference in Europe.

In mid-1992, European networks adopt the GSM-900 system and GSM terminals, which had a great expansive effect in Latin America, Asia, Oceania (Australia became a pioneer of this emerging technology) and much of the United States. and Canada.

Consequently, clearly with what has been exposed so far, it is easy to infer the great acceptance of users on a global scale and its commercialization.

Third generation (3G

As pressure grows from users in their demands for access to fast, reliable and affordable mobile technology. It arises from the design developers, the UMTS system is conceived, determined by the W-CDMA technology.

Fourth Generation 4G

With this generation, it presents a portfolio of novelties that cover substantial improvements related to better and greater security and quality of service (QoS) and a great deployment in relation to speed, an attribute that exceeds 100 Mbit/s in movement and 1Gbit/s. It's in sleep mode.

We must say that this technology is based on the IP protocol, becoming a supersystem and a network of networks by having the availability of a meeting point between wired and wireless networks.

The versatility of this technology borders on the unimaginable from the point of view of the response that the user demands precise and fast information; Among the professional world at this time, the massive use of Smartphones has become a necessary and basic consumer good, it is practically impossible to interact with reality without resorting to the use of this tool.

Fifth Generation 5G

It is a technology conceived in the current moments (2020) that represents a vision inspired by wireless connections.

It constitutes an ambitious project that in some countries, are resistant to the adaptation of such technology, because their governments consider that it could influence security and defense mechanisms, turning them into a potential weapon for their interests and especially, a hindrance in the design and application of public policies. If you like advanced topics in technology, I invite you to read Satellite technology

Health is mentioned as an example, currently hit by a pandemic. It is the obligation of governments to design correlative strategies to the magnitude of the problem to be faced.

The United States government is reluctant to adopt this technology, alleging reasons of sovereignty and government interest,

For their part, countries such as Chile have expressed interest in applying the technological benefits offered by these advances.

Cellular telephony has become a service where information is raw material to exploit and refine its results in response to the concerns presented by our global reality.

Who would have thought in the last century to have in the palm of one's hand Internet services, textual and voice data, text messaging, storage capacity for contacts, photos, radio, TV, videos, Office, pdf files, WhatsApp applications and others? .

Everything expressed gives us a vision of domain and security as reliable sources to take on the challenges that the future holds for us.
