PRESENTATION
The history of the creation and
development of mobile phones

2.

• Thirty years ago, on March 6, 1983, a new era in the
world of communication technology began: the first
mobile phone in the modern sense of the word,
designed by Martin Cooper of the American
company Motorola, went on sale. However, by that
time, the history of the creation of this means of
communication had been going on for more than
one decade...The idea of turning telephone
communication into wireless communication arose
almost immediately after the invention of the
telephone by Alexander Graham Bell in 1877.
However, the first experiments of both Bell and
Edison were rather fruitless. On the contrary, the
attempts of the self-taught Nathan Stubbledfield
(1860–1928) to transmit voice and other sounds by
induction – through water, through air, and even
through land – by water, through air, and even
through land – were very curious and not without
results. But even here it did not go beyond one-time
demonstrations, more or less successful.

The situation changed when, at the turn of the
century, practical experiments on the transmission
and
reception
countries
and
of
radio
waves
began
in
various
thanks
to
the
efforts
of
many
outstanding
scientists
at
once,
this
time
they
aroused
the
interest
of
the
widest
public
and
clearly
showed
a
new
way
exchanging
information
that
could
replace
not
of
only
the
usual
telegraph, but, probably, even the telephone. A
pioneer in this field was the Canadian inventor
Reginald Fessenden (1866–1932), who in his youth
managed to work as an assistant to Edison: in 1900
he was able to transmit sound by radio (albeit
with
great
distortion),
and
six
years
later,
having perfected the modulation of low-frequency
signals
during
transmission,
he
organized
the
first radio broadcast, with violin playing and a
clearly distinguishable reading of a passage from

• A couple of decades after that, radio broadcasting became quite a familiar medium, and
radio communication turned into a new hobby of enthusiasts from all over the world. Of
course, in the first case, it was only a matter of receiving a signal from a broadcasting
station, and in the second case, designing your own radio stations (and exchanging messages via
Morse code) remained a no-brainerAnd therefore it is the lot of a rather narrow circle of amateurs.
On the other hand, walkie-talkies gradually became more and more portable – and, starting in the
1920s, such a means of communication began to come into official use, primarily in the police and in
the army. Cooper's group could boast of the first more or less working prototype of a mobile phone
just 90 days after the start of the project. April 3, 1973 is often cited as the birth date of modern
cellular communications: Martin Cooper called Joel Engel, the head of research at rival AT&T, on the
street with news of his progress. However, it should be noted that the idea of considering March 20,
1902, when Nathan Stubblefield called from the steamer Bartholdi to the shore, as the date of the
first conversation on a mobile phone, seems no less reasonable, and the successful experiments of
L. I. Kupriyanovich and other pioneers and enthusiasts of personal radiotelephone communication
should not be written off in any way.

But what you can't argue with is Motorola's obvious priority in turning a
technical prototype into a real commercial product. Beginning in 1973,
the company invested $100 million in the Mitchell and Cooper project,
and yet it took a full decade for the mobile phone to reach store
shelves. Inventors had to solve several problems at once: first of all,
they had to achieve a reduction in the size of the device and the level of
its power consumption, because previously only car engines could cope
with this, and in addition, they had to organize the creation of all the
necessary infrastructure for cellular base stations. The second task was
solved thanks to the activities of AT&T: despite all the competition, the
telecommunications giant was no less interested in deploying a wireless
telephone network than Motorola, and by the early 1980s it was able to
get the federal agency to license the necessary frequencies for
consumer radio communications.

Examples of the development of phones
IBM Simon (1992)
In 1992, mobile phones were unknown in Russia, but abroad they were large, sometimes in the form of
suitcases.
The IBM Simon was a kind of DOS computer with a graphical interface and a touch screen.
This "flagship" cost $900 and sold about 50,000 units. It was the first smartphone of its time1.
Nokia 5110 (1998)
The Nokia 5110 was an affordable and popular model.
It was characterized by a sturdy body, a bright display and a wonderful game "Snake".
This phone has become a symbol of the 90s and has left its mark on the history of mobile devices.
Siemens S10 (1997)
The Siemens S10 was one of the first phones with a color display.
It also supported SMS and had a compact design.
This machine has become popular due to its innovative features.
Sony Ericsson T610 (2003 year):
The T610 was a stylish and feature-rich phone.
It had a camera, an MP3 player, and MMS support.
This device became popular among young people and influenced the design of future models.
Benefon ESC! (2000)
Benefon ESC! was one of the first telephones with a GPS navigation system.
It offered navigation for travel and opened up new possibilities for mobile devices.
Not only do these phones bear witness to the past, but they have also had a significant impact on the
development of the mobile industry.

Next-Generation Phones: Impact on the
World
Modern mobile phones are not only convenient for us, but also have a significant impact on the
world's culture, economy, and society. Let's take a look at how they help the whole world.
Communication & Communication:
Mobile devices have become our constant companions, allowing us to connect with people anywhere
in the world.
They have simplified communication, business negotiations, family ties, and even helped in
resolving international crises.
Internet & Education:
Smartphones provide access to the internet, which promotes education and self-education.
They help you learn, research, get news, and grow.
Medicine & Healthcare:
Mobile apps help monitor health, monitor nutrition, physical activity, and even diagnose
diseases.
Telemedicine allows you to consult with doctors from a distance.
Economy and Business:
Mobile payments, online banking, and e-commerce have become an integral part of the modern
economy.

Social Media & Culture:
Mobile phones facilitate the exchange of
information, the creation of content and the
formation of cultural trends.
They help us stay up to date, communicate
with friends, and even find new
acquaintances.
Ecology and sustainability:
Mobile devices are driving the development of
environmentally friendly technologies and
reducing the use of paper documents.
They help us monitor the state of the
environment and take measures to preserve it.
All of this makes modern mobile phones an
integral part of our lives and helps the
world become more connected, informed and
sustainable.

The History of the Invention of the
Telephone
1. Alexander Graham Bell
The
inventor
of
the
telephone
is
considered to be Alexander Graham Bell,
an
American
scientist
of
Scottish
origin. In 1876, he received a patent
for his invention, which he called an
"improved
model
of
the
telegraph."
On
the very first phone call in the world,
Bell
contacted
Watson,
who
his
was
in
assistant,
the
next
Thomas
room,
saying, "Mr. Watson, come over, I want
to see you."

2. Antonio Meucci
In
Italy,
it
is
also
believed
that
Antonio Meucci (1808–1889) was the author
of
the
first
telephone.
He
had
been
studying the electromagnetic transmission
of sounds for a long time. In 1849, while
working
on
purposes,
shock
Meucci
therapy
for
medical
developed
the
idea
of
transmitting the human voice, and by 1856
he
was
able
to
transmit
his
own
voice
through wires. However, Bell received a
patent for his phone two years later1.

3. Johann Philipp Reis
Self-taught German scientist Johann Philipp
Reis (1834–1874) is famous for inventing a
telephone-like device that was later named
after him. Reis's "telephone" recorded the
voice, turned it into electrical impulses, and
wired it to another device. Reis built his first
successful telephone in 1861, but his reports
were rejected by the scientific community. In
1875, the famous American inventor Thomas
Edison used a translation of Reis's
manuscripts to create a carbon microphone
and called Reis "the first inventor of the
telephone."
