Nowadays we get used that cheap mobile phones provide us with various kinds of entertainment, though at the beginning the main goal of the creation of such devices was... security. It should be said that the first country which used radio telephony was Germany. All the first-class trains between Berlin and Hamburg were equipped with such devices since 1926. Note that the Second World War played important role in the development of various modern devices, weapons and equipment. And mobile phones are not the exception to this rule. With the addition of Mobile SIM Cards today mobile phone use has never been more affordable.
Of course, radio telephony which was used in German tanks as well as on passenger airplanes during the Second World War, can't be called mobile phones, but still it is the root of these digital devices. It should be noted that in all the above mentioned cases, the specialists were necessary for providing such services and only since 1950 an untrained end consumer was able to use radio telephony. In other words, only since that time we can talk about the two-way communication where the second person is just the usual man, but not a professional.
As early as 1947, Douglas H. Ring and W. Rae Young, Bell Labs engineers offered hexagonal cells for mobile phones. But cellular ideas were not developed till 1960. The other thing is with the automatic mobile phone system or MTA (Mobile Telephone system A). It was developed much earlier in 1956 by Ericsson and released in Sweden. Of course, it was really something new, because such a system was fully automatic, but still had such a disadvantage as the phone weight which was up to 40kg. So, would you like to take this device with you for a walk? The updated version, MTB, weighted only 9 kg.
At the beginning, mobile phones were installed in cars and became the prerogative of rich businessmen. It was rather a useful device for work than the thing which can enhance the prestige of someone... but only at the beginning. Nowadays mobile phones continue to be a kind of accessories. As a rule, people estimate a person by her watch, bag and of course, Nokia mobile phone. So, it can be said that this thing has become a status symbol. Or is it, probably, just a good promotion?
