GSM (Global System for Mobile
communications) is a standard technology for mobile phones. Initially
based in Europe and where the original GSM acronym is taken from
(Groupe Spcial Mobile) it has long since spread its wings to
encompass much of the world, to easily become the most popular
technology for cellular services. With approximately 80% of the world's
mobile phones using GSM, its flexibility and digital features make it a
very popular choice. It has large benefits in the ability of roaming,
or using your phone in other parts of the world, and it is a fully
digital service that superseded the original analogue services. This
advance led to the technology being able to incorporate many more
features as well as being able to send and receive packets of data.
Roaming is an important feature for consumers, and GSM comes into its
own in with its ability to link together GSM base stations across the
world, for wide and continued service. On a basic level, one GSM
provider will have an agreement with another and vice versa, ensuring
that a consumer, when passing from one country to another will still be
able to get good GSM service. This helps to cut out extortionate
roaming charges for using services outside of your own comfort zone.
The other benefit of GSM
mobile networks is their reliance on SIM
(Subscriber Identity Module) cards. What this allows is for the same
phone to be operable on different GSM carriers without the need to
change phones, as it carries your subscription details. Alternative to
this, when visiting another country you can simply purchase a local SIM
card and put it in your phone for cheaper calls.
Text messaging (SMS short message service) is a phenomena which rapidly
grew into a cultural change of not actually speaking to anyone via a
phone. With people, mostly youngsters, being able to write a text
message faster than they can talk, this was a pioneering technology
created by GSM. It wasn't long before the benefits of this new
alternative were picked up by other mobile phone carriers that used
different technologies, primarily CDMA (Code Division Multiple Access).
GSM mobile networks work on a cellular network and because of its great
uniformity it allows all GSM networks to have an emergency telephone
number (112), which can be used worldwide to get in touch with local
emergency services.
A cellular network, such as the GSM standard, operates by the antenna,
in this case the mobile phone, picking up a signal
from a cell (the broadcast range of a base station in the area). A
network of these base stations will ensure that a GSM network provides
good, consistent coverage to an end user wherever they go. GSM has a
much broader coverage across the world than CDMA. The network that
operates behind the handset operation involves a lot of unseen work.
This work and planning allows the network to reach further into rural
areas to ensure even remote coverage. GSM mobile networks are far
reaching across the globe now, and with a quad band phone, you can stay
connected whatever part of the world you are in. The flexibly make the
GSM standard the ever growing popular mobile phone carrier system.
