Understanding the Mobile World

The intertwining of telecom, banking, and M2M/IoT produces a new degree of complexity. We hope our COMPRION glossary helps you to get a good overview of all the connected terms, technologies, and concepts.


Conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers. The model is a product of the Open Systems Interconnection project at the ISO, maintained by the identification ISO/IEC 7498-1.

The entire data transmission from and to the chip card can be represented by the OSI Model. A distinction is made between the electrical events on the I/O line, the logical sequences of the actual transmission protocols, and the behavior of the overlying application. The behavior and the sequences within and between these layers are specified in various international standards.

The OSI Model is organized into seven layers, three application-oriented, two transport-oriented, and two hardware-oriented.
