Remember those days when portable
phones were heavier (and larger) than
bricks? Back in those primitive days,
business people (the only ones who could
afford such an expensive service) spent
as much on doctors and massages (to get
rid of the contractures caused by
carrying around those eight pound
monsters) as they spent on mobile
telephony itself. Worse yet, those huge
phones were rarely sold, but instead
they were leased, so you didn’t even own
your own equipment.
Luckily for us, mobile telephony has
evolved in such a way that today cell
phones are even more used that toasters
or Television sets, as most houses have
at least one phone per family member,
but rarely more than three TVs per
household.
Amazing advances in technology made cell
phones evolution possible; with the
arrival of smaller electronic components
every day, cell phones manufacturers
like Motorola or Sony Ericsson are able
to include much many features in the
same physical space. Better yet, many
electronic equipment manufacturers have
started to produce cell phones
themselves, making what was almost a
monopoly in those days into a very
competitive market.
Today, cell phones are almost as small
as a lighter, and some are in fact
smaller than a pack of cigarettes. This
makes mobile phones really easy to use
and carry in your pocket in such an easy
way that most people forget they have a
phone until it starts ringing.
And if we talk about ringing phones, we
can not avoid mentioning one of the
latest fashions: ringtones.
Monophonic tones, polyphonic music and
different tones for different incoming
calls are several features that are very
common nowadays. Some phones even allow
you to choose your own MP3 file to play
as a ringtone (I got a “Hey! Answer me!”
ringtone I have recorded myself, hehe).
What’s more, modern cell phones take
communication to the next level by
including the capability to take
pictures and record real time video.
When I look back to those primitive
times and then I compare those monsters
to modern equipment, I cannot stop
wondering what new and amazing features
will future cell phones include.
Even though the popularity of mobile
phones is at an all time high, the
complexity of the systems driving this
technology usually means that only those
involved with the industry have a
complete understanding on how mobile
phones actually work.
Until recently, and like most of today’s
millions of mobile phone users, I found
myself confused by the amount of
information on the subject, and even
when I found information which was
relevant, the terminology used was best
suited to someone with a degree in
telecommunications.
In truth, the technology is very easy to
understand when the information is
presented in simple terms. In this
article I’ll try to do just that –
simplify the technology.
The concept: Even though technology has
become widely known as wireless, this is
only true between your handset and your
nearest receiving antenna. After that
the connection goes through a series of
telephone wires until it reaches the
antenna nearest to the person you are
calling – assuming the call is to
another mobile.
Your handset and provider: If you put
features to one side, one handset works
in much the same way to any other and
the same is true of the actual network
provider you choose to go with.
Manufacturers such as Nokia and Samsung
dedicate themselves at producing the
handsets and network providers such as
Vodafone and O2 focus on the structure
of the network itself.
Cellular networks: The term “Cellular”
has been derived from the fact that each
antenna only has a reach of a limited
area; this area is known as a cell. By
placing antennas in various part of the
country, providers have created Cellular
network. The total area within these
cells, determines the coverage of a
network service provider.
Making and receiving calls: When you
make a call, your mobile phone locates
the nearest antenna available for your
network and connects you to the wired
telephone system. The telephone network
then locates the nearest antenna
available for the person you are trying
to call and connects you to that mobile.
The opposite happens when you receive a
call.
Your location: For a connection to be
successful, your network needs to know
where your phone is located. To achieve
this you mobile phone is in constant
communication with your nearest antenna.
If you move location, and your original
antenna no longer has enough reach to
connect to your mobile, your phone will
automatically search for another one.
The new antenna then informs the system
of your new location.
Conclusion This article is by no means
trying to undermine the achievements or
the potential the technology has to
offer. Instead, it is intended to
provide an insight to the key elements
of the mobile phone technology which
would otherwise remain invisible to
everyday users.
