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.


General term for smart card, chip card, or SIM card used in the context of telecommunications.


Technical specification (ETSI TS 102 223) that provides mechanisms that allow applications, existing in the UICC, to interact and operate with any terminal that supports the specific mechanism(s) required by the application.


Mode that enables NFC devices to act like smart cards, allowing users to perform transactions such as retail purchases and transit access with just a touch.


Data input device that reads data from any kind of card. Contactless smart card readers use radio waves to communicate with, and both read and write data on a smart card.


Next to UMTS, one of the 3G technologies that allow a higher data rate than GSM (for 2G) does. CDMA2000 is an upgraded version of CDMA.


Brand name for Interim Standard 95. IS-95 (also known as TIA-EIA-95) is the first CDMA-based digital cellular standard by Qualcomm. It is a 2G mobile telecommunications standard that uses CDMA, a multiple access scheme for digital radio, to send voice, data, and signaling data (such as a dialed telephone number) between handset and cell sites.


General term for a card that contains one or more semiconductor chips. Chip cards may have memory ICs or microprocessor ICs. The term is often used synonymously with smart card or ICC.


Form of multiplexing that allows several transmitters to send information simultaneously over one single communication channel (for example, wireless networks) instead of assigning a specific frequency to each user as it is usual for GSM systems. CDMA encodes individual conversations by random digital sequence. It offers a transmission speed of up to 14.4 Kbps in its single-channel form and up to 115 Kbps in an eight-channel form.


In ISO/IEC 7816-3, the coding convention determines the representation of logical values by voltages and how a transmitted byte is serialized. For direct convention, a high voltage of 5 V (or 3 V or 1.8 V, respectively) represents a logical 1, and a byte is transmitted beginning with the lower order bit. For inverse convention, 0 V represents a logical 1, and the higher order bit of a byte is transferred first. For both conventions, I/O is in high state when no data is transferred. The coding convention used by Device Test Center is displayed as a message in the Info view.


Transmission by two PICCs in the same electromagnetic field and during the same time period, such that the PCD is unable to distinguish from which PICC the data originated.


It is possible to compare the test cases and verdicts of two test plans in a report. This enables you to identify which test cases have been added or removed and if the verdicts have changed.


In general, compliance means conforming to a rule, such as a policy, standard, or law. Regulatory compliance describes the goal that organizations aspire to achieve in their efforts to ensure that they are aware of and take steps to comply with relevant laws and regulations.


Conformance testing or type testing is testing to determine whether a product or system conforms with the requirements of a specification, international standard, or regulation. It is often physical testing but may involve chemical testing or requirements for efficiency or interoperability. To aid in this, many test procedures and test setups have been developed, either by the standard's maintainers or external organizations, specifically for testing conformance to standards. Conformance testing is sometimes performed by external organizations, which is sometimes the standards body itself, to give greater assurance of compliance.


Functional unit in the terminal that provides the contactless communication interface in the SWP/HCI context. The term is defined and used in ETSI documents.
