GSM (Global System for Mobile Communications).............. GSM is the branded term referring to a particular use of TDMA (Time-Division Multiple Access) technology. GSM is the dominant technology used around the globe and is available in more than 100 countries. It is the standard for communication for most of Asia and Europe. GSM operates on four separate frequencies: Youll find the 900MHz and 1,800MHz bands in Europe and Asia and the 850MHz and 1,900MHz (sometimes referred to as 1.9GHz) bands in North America and Latin America. GSM allows for eight simultaneous calls on the same radio frequency and uses narrowband TDMA, the technology that enables digital transmissions between a mobile phone and a base station.

This technology allows several callers to share the same channel at the same time.
