Global System for Mobile Communications
GSM

    (GSM) One of the major standards for
   digital mobile communications.  In 1982, the Groupe Speciale
   Mobile was formed by the Confederation of European Posts and
   Telecommunications (CEPT) to design a pan-European mobile
   technology.  GSM was named after the "Groupe de travail
   Spéciale pour les services Mobiles" group of CEPT that wrote
   the first GSM specifications.

   By 2011, GSM was in use in over 60 countries and serving over
   six billion subscribers.  The GSM standard uses the 900 MHz,
   1800 MHz and 1900 MHz bands.

   GPRS allows packet switched data communications over GSM,
   and is widely used for web and electronic mail access from
   mobile devices.
