Cell phone timeline: evolution since 1930

The cell phone timeline It goes beyond the 70s, the date on which his birth is located. 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 may not remember, but they may also admit that they did it many times. There is an average: 110 times a day.

Cell Phone Timeline: 1930s to Today

Portable radios

1938

What many do not know is that the cell phone finds an ancestor in the first AM portable radios, the SCR-194 and 195. These models were produced for the USA, at the 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.

1940

Another development for military purposes, which can be counted as an antecedent of the cellular, 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 World War II.

1942

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 in the water its signal could reach 3 miles.

1946

This was the year that he was introduced to the first commercial mobile telephone service: the Mobile Telephone System (MTS), developed by Bell System.

It weighed 80 pounds and worked with limited calling bands available from AT&T, costing as much as $30 a month with additional per-call charges.

1956

Ten years after Bell System’s MTS comes Ericsson’s Mobile System A (MTA), the first partially automatic mobile system for automobiles that began commercialization in Sweden.

A year later, Du Mont engineer James A. Craig, in the United States, demonstrates the first radiotelephony equipment that allows telephone calls from vehicles to and from vehicles to be retransmitted completely unattended through the local phone companies.

1964

Starting this year, owners of cars with built-in phones in the United States began to see lighter cell phones with push buttons, but with inaccessible prices and rationed service.

The rise of the cell phone

1973

The mobile phone leaves the car thanks to DynaTAC (Dynamic Adaptive Total Area Coverage), with which former Motorola vice president Martin Cooper made the first private phone call.

The device in question weighed 1.1 kg and its dimensions were 228.6 x 127 x 44.4 mm. The user could talk for 30 minutes and it took almost 10 hours for its battery to fully charge.

In terms of connectivity, these first devices belong to the «zero generation» (0G), precisely because they do not have that capacity.

1982

Nokia appears on the cell phone market and the first international mobile service is launched, that is, the first generation (1G) of mobile communications.

1983

Motorola’s DynaTAC 8000X cell phone is being marketed to the public. By this time it weighed less than 2 pounds and was running on AMPS, North America’s first 1G analog service.

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 telephone numbers.

However, it was still a technology accessible to few: it cost almost $4,000 (almost $9,000 today), in addition to the fact that its design was more geared towards businessmen.
