The history of mobile phones

From 1952 to 1991
From the several-pound car phone to the modern smartphone. We document the thrilling evolution of mobile phones and mobile networks. In the beginning, everything here revolves around the rocky evolution of the mobile phones of the first hour.
Handy, versatile and always present. Dealing with compact mobile phones have today become so obvious that many cell phone users even can not imagine that a few years ago mobile phones were not yet mobile handy. Speak the contrary: A look back at the beginnings of mobile phones shows that mobile phone calls over decades was synonymous with the – very expensive luxury – in a car with an interlocutor on a large distance to be able to.
The first documented car phone was installed in 1952 in the city of Bremen in a taxi. More hideous than the high weight of 16 pounds was the immense cost of the forefather of all the car phones, for a price of around 15,000 marks the device was about three times as expensive as a VW Beetle. Another primitive car phone presented the company Ericsson in 1956 in Stockholm. The prototype was still the size of a suitcase, weighed about 40 kg and was about as expensive as the car in which it lay.
With the introduction of the first nationwide cellular network (network A) 1958 in Germany, mobile telephony was alone because of the exorbitant cost of a privilege of important politicians and large employers. The first standard model B72 cost the company TeKaDe the then astronomical sum of 15,000 marks. Another cost factor: the first generation car phones were for a long time, so expansive, heavy and complex, that has already cost the costly installation a small fortune.
It took a long time in the following years, reaching up to size and weight to acceptable levels. In 1972 it succeeded in Ericsson, a car phone to trim to a weight of under 10 kg to. The cost of the car assembly led to reductions, though substantial, but the device still remained firmly entrenched with the car.
In 1982 saw the B-network phone Mobira Senator by Nokia for more communicative mobility. By means of a carrying handle, this device was removed from the car. The mobility was nevertheless very limited, because apart from the fact that the 9.8 kilograms heavy phone still had the proportions of a gasoline canister, it had to Mobira Senator after a few hours back to the recharging dock.
Despite this limited portability of Senator Mobira inspired the entire telecommunications industry. More and more manufacturers are packed receiver unit, battery and phone in a more or less handy device, and knew it with a carrying handle. In the following years decreased while increasing the weight, while the battery power still continued to rise. The extremely high price, however, remained unchanged. Paid by the end of the eighties had a car phone, mobile phone users for at least 6,000 marks.
With the introduction of powerful C-net for those days in 1985 was mainly the German telecommunications industry a new impetus. With smaller and smaller batteries, and the introduction of magnetic stripes on the phone addressing – the forerunner of today’s SIM card – Mobile phones are much smaller and more sustained. Nokia Talkman Mobira 320F (1986) for example, weighed “only” 4.7 kilograms and came out with a fully charged battery around ten hours without a power outlet. Leaves from a cell phone, which lies comfortably in your pocket, you could say because of the size of a shoebox but still do not.
A small, in the truest sense of the word sensation managed one years later, again with the Nokia Mobira Cityman. This device weighs just 800 grams, had only the size of a large telephone receiver. The Mobira Cityman obtained in 1989 a special celebrity, when Mikhail Gorbachev, the communications device used during his visit to Germany, to inform his office in Moscow by the reunification plans (hence the nickname Gorby). Not least for this reason, this was about 10,000 marks expensive mobile phone in the late eighties the prestige object of many yuppies.
Almost simultaneously, the German Telekom brought the well-known model Pocky turn, the first real mobile phone on the market. The cost Pocky Mark 8600 and functioned only in the German C-Netz.
