What is GSM?
GSM (Global System for Mobile communication) is
a digital mobile telephony system. GSM uses a
variation of time division multiple access (TDMA)
and is the most widely used of the three digital
wireless telephony technologies (TDMA, GSM and
CDMA).
GSM is a second generation Cellular
standard developed to cater voice services and
data delivery using digital modulation.

How GSM Works
GSM networks come into play when it comes to
actual tracking. When and if the phone is turned
on, these networks capture the signal, then sends
it to the satellite for processing and the
satellites sends the data to the person with the
query.
There is a need of network service providers,
those who enable communication between mobile
phones, as well. The phone must have a SIM card
installed which connects to the service provider
network as often these networks double up as GSM
networks. Using these combinations, the actual
location of the GPS GSM enabled phone can be
known.

Advantages Of GSM
GSM is used all over the world with more than 450
million users. International roaming facility
permits the use of one phone throughout the world
unlike CDMA which will work in Asia, but not
European nations. GSM is established, started in
the mid-80s due to which a more stable network
with healthy features are available.
The accessibility of Subscriber Identity Modules
(SIM cards), which are smart cards provide
secure data encryption to give GSM m-commerce
advantages. GSM service is in more than 200
different countries, so it is quite easy to
simply use your GSM phone when you are in one of
these countries.

Disadvantages of GSM
Incase of GSM, SIM cards, individual
authentication keys of the users are stored in
the authentication centers. Any person with the
rights and qualifications to access to
authentication center can manipulate these to
impersonate that mobile user.

Security algorithms used in GSM e.g. A3, A5, and
A8 are all undisclosed algorithms. But
researchers have proved that these algorithms
cannot guarantee 100 security. Privacy of a
call and mystery of a subscriber are only assured
on the air interface among the mobile station and
the base station subsystem leading to likelihood
of eavesdropping of voice data.
