GSM (Global System for Mobile communications) is a digital cellular communications system. It was developed in order to create a common European mobile telephone standard but was rapidly accepted worldwide. GSM was designed to be compatible with ISDN services, but is now being integrated into Next Generation Networks. This course gives a broad overview of the GSM system and explains in greater depth how nodes in GSM communicate to provide voice and circuit-switched services.
