GSM System Architecture
GSM stands for the Global System for Mobile Communications. It is a standard initially created to solve the incompatibility of the 1G cellular systems and equipments in Europe. Originally, it operates in the 900 MHz band, but subsequently the 1.8 GHz and 1.9 GHz bands are also supported.
