The cell phone timeline it goes beyond the 70s, the date on which he was born. Specifically, the origins date back to the late 1930s with the invention of portable radios in the United States..
Today cell phones are part of the daily life of most of the inhabitants of this planet and are a clear example of the dizzying speed of technological evolution.
If you ask a person how many times they have unlocked their cell phone today, they probably don't remember it, but they also likely admit that they did it many times. There is an average: 110 times a day.
What many do not know is that the cell phone finds an ancestor in the first portable AM radios, the SCR-194 and 195. These models were produced by the US Army Signal Corps Engineering Laboratories.
Weighing approximately 25 pounds and having a range of 5 miles, these "walkie talkies" were widely used during World War II..
Another development for military purposes that can be counted as an antecedent of the cell phone was Motorola's SCR-300 radio transceiver..
Although it weighed more (32 and 38 pounds) and had a shorter range (3 miles) than the SCR-194 and 195, it was also popular with the Allies during WWII..
In the same line of portable radios is the first "handie talkie", SCR-536, developed by Motorola with a weight of 5 pounds and a range on land of 1 mile, while on the water its signal could reach 3 miles.
This was the year that the first commercial mobile telephone service was introduced: the Mobile Telephone System (MTS), developed by Bell System.
It weighed 80 pounds and worked with limited calling bands available from AT&T, costing up to $ 30 a month with additional charges per call..
Ten years after the Bell System MTS, the Ericsson Mobile System A (MTA) appears, the first partially automatic mobile car system to be marketed in Sweden.
A year later, Du Mont engineer James A. Craig, in the United States, demonstrates the first radiotelephony equipment that allows vehicle phone calls to and fro to be retransmitted completely unattended over the local phone companies.
Starting this year, car owners with built-in telephones in the United States began to see lighter mobile phones, with push buttons, but with little accessible prices and with rationed service..
The mobile phone leaves the car thanks to the DynaTAC (Dynamic Adaptive Total Area Coverage), with which the former vice president of Motorola, Martin Cooper, made the first private phone call.
The device in question weighed 1.1kg and its dimensions were 228.6x127x44.4mm. User could talk for 30 minutes and it took almost 10 hours for his battery to fully charge.
Regarding connectivity, these first devices belong to the “Zero Generation” (0G), because they do not have that capacity..

This device, the first cell phone approved by the Federal Communications Commission (FCC) in the United States, offered 30 minutes of conversation, 6 hours on standby and could store up to 30 phone numbers.
However, it was still a technology accessible to few; It cost almost $ 4,000 (almost $ 9,000 today), plus its design was more geared towards businessmen.
The Mobira Talkman appears, increasing the time available for conversations that the DynaTAC had imposed.
Motorola once again pioneered its MicroTAC, the world's first pocket phone thanks to its flip design, in which the hardware was located in a hinged section of the phone, reducing the size of the device when not in use..
GSM Unveils 2G Digital Encryption Technology Three Years Later.
The Motorola International 3200 appears as the first digital mobile phone to use 2G technology.
Arguably, with the 90s, a race begins to improve the design of phones and to make them more portable so that any consumer can access them..
And at the end of the decade, multipurpose phones appeared with: games, calculator, clock, calendar, profile settings and colors on their screen..
The IBM Simon, a mobile phone, pager, fax and PDA, which also included a calendar, address book, clock, calculator, notepad, email, games and a touch screen with QWERTY keyboard is launched.
Motorola shows the public its StarTAC, which opened and closed like a clam, halving the size of the phone. It worked on 1G networks and then went to 2G.
With the Nokia 9000 comes the first cell phone that also includes mini-computer functions, despite its limited access to the web. It had an LCD screen and a full QWERTY keyboard, a first for a mobile phone.
That same year, Nokia released its model 3110, the most compact mobile phone available..
Nokia moves towards a more comfortable and ergonomic design; with its 8810 model it eliminates the external antenna or stub-antenna, and then launches other models with sliding keyboard.
Nokia innovates again with its model 3210, which allowed to send messages with pre-installed images; or the 7110, the first cell phone to incorporate Wireless Application Protocol (WAP), or what is the same: access to the web for mobile users.

In the last 7 years, the challenge of manufacturers has focused on developing devices with a battery that lasts longer and with an elegant, light and thin design.
Likewise, Android technology has been the north of many for allowing the download of the most popular mobile applications on the market.
From the point of view of content producers in the world, there has also been a race to develop products that can be consumed from different devices, especially from smartphones, since this mode of connection today represents 75% of web traffic.
