Welcome
back my fellow learners. Today we are going to speak about the mobile phone,
how it was invented and its consequent progress since then.
The
first ever mobile call was made by Martin Cooper, a senior engineer at the time
working for Motorola on April 3, 1973. Obviously having a quirky sense of
humour, his first call was to his rival company informing quite tongue in
cheek, that he was talking to them via a mobile phone. This phone however, was
bigger than a house brick, weighing a whopping 1.1kg, it provided you with
approximately 30 minutes of talk time, which let’s face it ladies would be
absolutely no good to us, and then it took a staggering 10 hours to re-charge.
However,
I am jumping the gun slightly, so let’s go back even further. The origins of
the mobile phone are very interesting to say the least. It started with that
famous man Alexander Graham Bell, who patented the first phone in 1876. This
was designed by using the telegraph as a rough guide. Phone calls would be
routed via operators, who would then in turn direct your call to the relevant
person.
Ericsson
being technically advanced as per normal, released the earliest cellular phone
system known in Sweden as the MTA in 1956. However, due to its bulk and weight
soon fizzled out, mobile phones back in the day could weigh up to 40kgs. A
lighter version soon came out in 1965 and was called the MTB.
However,
it was a young engineer living in Moscow called Leonid Kupriyanovich in 1957
first developed the wearable mobile phone, this was operated with the help of a
base station. The battery of this revolutionary phone lasted up to 30 hours,
and weighed 3kg, however, it only worked at a distance of 30km from the base
station. Later on that same year, this enterprising young man, came up with a
pocket version of this same phone, and it only weighed 0.5kg.
In
1970, Ames E Joel invented the handoff technology, thus ensuring mobile phone
users were not restricted within a certain distance of their base station. Ames
technology allowed people to make a call while passing through different cell
areas without loss of connection.
Since
then technological advances have progressed by leaps and bounds. Modern phones
now possess the ability to having a miniature office all stored on one phone.
