GSM - Global System for Mobile Communications
2G mobile telephone. Standard used in 2G digital mobile communication systems in Europe and Asia which specifies how data is encoded and transferred through the spectrum. GSM digitalises and compresses data related to a connection, transmitting it through a channel together with that of other users, using time-division multiplexing.
