Mobile Phone History In Brief |
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.
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?
