Mobile phones
Mobile phones:
definition and technology. Mobile phones, or cellular phones, are devices that
enable
Communication to
all types of telephones while moving over a wide area called the coverage area.
The term
‘cellular’ comes from the fact the phone calls are made through base stations,
communication towers or antennas, which divide the coverage area into cells. As
you move from cell to cell, the calls are transferred to different base
stations belonging to the same or a different telephone company. This
capability of mobile phones is called roaming. The phone is said to be out of range
when it cannot communicate with a base station.
A brief history
-1G, First
Generation phones started in the 1980s when Motorola introduced the first
hand-held phones. They used analogue technology and the main drawback was the
small number of channels that could be used at a time.
-In the 1990s, 2G
mobiles introduced digital transmission methods that converted voice into binary
information, increasing the number of channels, the speed of transmission
between the phone and the base station enabling a reduction in size. The most
common standard, GSM, Global System for Mobile communications, started to be
used at this stage. One of the features of this technology is the of SIM cards,
a type of smart card that contains the user’s information, the connection data
and the phonebook. It also enables the user to change service provider without
changing the handset.
-3G phones offer a
high-speed data transfer capability. Some of these phones are called smart phones
and combine PDA capabilities with the usual functions of a digital phone. The new
communication standard, UMTS, Universal Mobile Telecommunications System,
enables the multimedia transmissions that are becoming common nowadays.
-New standards are
being developed that will open the way to new 4G phones with an emphasis on
multimedia, real-time television and radio.

-Do
you know who invented the first telephone and when?
Mobile
phones
by
Craig Duncan
When Scotsman Alexander Graham Bell invented the
telephone in 1876, it was a revolution in communication. For the first
time, people could talk to each other over great distances almost as clearly as
if they were in the same room. Nowadays, though, we increasingly use Bell’s
invention for emails, faxes and the internet rather than talking. Over the last
two decades a new means of spoken communication has emerged: the mobile phone.
The modern mobile phone is a more complex version of the two-way
radio. Traditional two-way radio was a very limited means of communication. As
soon as the users moved out of range of each other’s broadcast area, the signal
was lost. In the 1940s, researchers began experimenting with the idea of using
a number of radio masts located around the countryside to pick up signals from
two-way radios. A caller would always be within range of one of the masts; when
he moved too far away from one mast, the next mast would pick up the signal.
(Scientists referred to each mast’s reception area as being a separate “cell”;
this is why in many countries mobile phones are called “cell phones”.)
However, 1940s technology was still quite primitive, and the
“telephones” were enormous boxes which had to be transported by car.
The first real mobile telephone call was made in 1973 by Dr
Martin Cooper, the scientist who invented the modern mobile handset. As
soon as his invention was complete, he tested it by calling a rival scientist
to announce his success. Within a decade, mobile phones became available to the
public. The streets of modern cities began to feature sharp-suited characters
shouting into giant plastic bricks. In Britain the mobile phone quickly became
synonymous with the “yuppie”, the new breed of young urban professionals
who carried the expensive handsets as status symbols. Around this time many of
us swore that we would never, ever own a mobile phone.
But in the mid-90s, something happened. Cheaper handsets and
cheaper calling rates meant that, almost overnight, it seemed that everyone had
a mobile phone. And the giant plastic bricks of the 80s had evolved into smooth
little objects that fitted nicely into pockets and bags. In every pub and
restaurant you could hear the bleep and buzz of mobiles ringing and registering
messages, occasionally breaking out into primitive versions of the latest pop
songs. Cities suddenly had a new, postmodern birdsong.
Moreover, people’s timekeeping changed. Younger readers will be
amazed to know that, not long ago, people made spoken arrangements to meet at a
certain place at a certain time. Once a time and place had been agreed, people
met as agreed. Somewhere around the new millennium, this practice started to
die out. Meeting times became approximate, subject to change at any moment
under the new order of communication: the Short Message Service (SMS) or
text message. Going to be late? Send a text message! It takes much less effort
than arriving on time, and it’s much less awkward than explaining your lateness
face-to-face. It’s the perfect communication method for the busy modern
lifestyle. Like email before it, the text message has altered the way we write
in English, bringing more abbreviations and a more lax approach to language
construction. The160-character limit on text messages has led to a new,
abbreviated version of English for fast and instantaneous communication.
Traditional rules of grammar and spelling are much less important when you’re
sitting on the bus, hurriedly typing “Will B 15min late - C U @ the bar. Sorry!
:-)”.
Mobile phones, once the preserve of the high-powered businessperson
and the “yuppie”, are now a vital part of daily life for an enormous amount of
people. From schoolchildren to pensioners, every section of society has found
that it’s easier to stay in touch when you’ve got a mobile. Over the last few
years mobiles have become more and more advanced, with built-in cameras, global
positioning devices and internet access. And in the next couple of years, we
can expect to see the arrival of the “third generation” of mobile phones:
powerful micro-computers with broadband internet access, which will allow us to
watch TV, download internet files at high speed and send instant video clips to
friends.
Alexander Graham Bell would be amazed if he could see how far
the science of telephony has progressed in less than 150 years. If he were
around today, he might say: “That’s gr8! But I’m v busy rite now. Will call U
2nite.”
