GSM (Global System for Mobile communications) is
an open, digital cellular technology used for
transmitting mobile voice and data services. GSM
differs from first generation wireless systems in that
it uses digital technology and time division multiple
access transmission methods. GSM is a circuit-
switched system that divides each 200kHz channel
into eight 25kHz time-slots. GSM operates in the
900MHz and 1.8GHz bands in Europe and the
1.9GHz and 850MHz bands in the US. The 850MHz
band is also used for GSM and 3GSM in Australia,
Canada and many South American countries. GSM
supports data transfer speeds of up to 9.6 kbit/s,
allowing the transmission of basic data services
such as SMS (Short Message Service). Another
major benefit is its international roaming capability,
allowing users to access the same services when
travelling abroad as at home. This gives consumers
seamless and same number connectivity in more
than 210 countries. GSM satellite roaming has also
extended service access to areas where terrestrial
coverage is not available.
Today's GSM
GSM (Global System for Mobile communications) is
the technology that underpins most of the world's
mobile phone networks. The GSM platform is a
hugely successful wireless technology and an
unprecedented story of global achievement and
cooperation. GSM has become the world's fastest
growing communications technology of all time and
the leading global mobile standard, spanning 214
countries.
Today, GSM technology is in use by more than one in
five of the world's population - by June 2006 there
were over 2 billion GSM subscribers, representing
approximately 80% of the world's cellular market.
The growth of GSM continues unabated with almost
400 million new customers in the last 12 months

The progress hasn't stopped there. Today's GSM
platform is living, growing and evolving and already
offers an expanded and feature-rich 'family' of voice
and multimedia services.
