What is GSM?
Originally called Groupe Sp¨¦cial Mobile, it is commonly known as the Global System for Mobile Communications.
It is a cellular network that operates in four different frequency ranges: 850MHz, 900MHz, 1,800MHz and 1,900MHz. Scandinavian countries use 400MHz and 450MHz frequency bands.
The network consists of the base station subsystem, the network and switching subsystem, and the GPRS core network (an optional part that enables packet-based data transmission.
