Economical growth which is a target in any country all over the globe requires sophisticated powerful communication systems. They have to be connected to each other in order to form worldwide communication networks. Today this target is already achieved for the fixed telephone networks. During the eighties the demand for mobile communications increased strongly, because people spent more and more time in traveling. Business traveling follows mainly the corresponding business opportunities, becoming more international. In consequence, the need for an immediate information exchange (voice + data) regardless the location of communicating partners became the driving point for the development of the mobile communication. The list of requirements forming the bases for a sophisticated mobile communication system therefore comprised a large set of features and performances, as for instance roaming within and between networks even crossing boarders, a broad spectrum of services, privacy by ciphering and many features more.
The GSM System was designed during the 1980's and entered operation in various European countries during 1992. GSM was designed internationally, in standardization committees by the major European communications operator and manufacturers as Italtel.
The GSM system architecture is composed of three main subsystems and two main service centers:
Italtel offers a complete GSM System composed of these subsystems, based on the European standard, so that all of its parts are compatible with subsystems from other manufacturers.
In addition, Italtel offers the CCW (Combined Cellular & Wired) system for telephone services in rural and mixed geographical areas like small communities (farms)/cities. The CCW IS a product based on GSM Technology.
