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.


Standardization body that develops open standards for the mobile phone industry.


Application programming interface that enables the applications running in the mobile operating system to communicate with Secure Element (SE) applications.


Device, previously called an oscillograph and informally known as a 'scope', is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time. In COMPRION Software, it is called Analog Scope.


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.


Various methods of distributing new software updates, configuration settings, and even updating encryption keys to devices like cell phones, set-top boxes, or secure voice communication equipment (encrypted 2-way radios). One important feature of OTA is that one central location can send an update to all the users; who are unable to refuse, defeat, or alter that update, and it applies immediately to everyone on the channel.
