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.


Patented by Innovatron, it is a type of protocol that uses the same physical layer as ISO/IEC 14443 Type B but with proprietary upper layers.


Technical specification (ETSI TS 102 124) that allows (U)SIM cards to download data through the phone’s high-speed data channel like GPRS and 3G onto the (U)SIM. Services like RAM and RFM will be significantly faster through BIP and are therefore ideally suited for efficient administration (loading, updating) of applications on the (U)SIM.


Basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. The most common representation of these values are 0 and 1. The term 'bit' is the abbreviated form of binary digit.


Anti-collision method for PICCs of Type A, employing collision detection at bit level within a frame.


In ISO/IEC 7816-3, a bit sequence consists of 1 start bit, 8 data bits, and 1 parity bit. It begins with the first falling edge after a reset or after a previous bit sequence, and ends with the parity bit.


In Single Wire Protocol (SWP), bit streams that do not have the same or rationally related bit rates are synchronized by bit stuffing. The location of the stuffing bits is communicated to the receiving end of the data link, where these extra bits are removed to return the bit streams to their original bit rates or form. Bit stuffing is used to synchronize the channels before multiplexing or to rate-match two single channels to each other.


Unit of digital information in computing and telecommunications that most commonly consists of eight bits. These are designated b8 to b1, from the most significant bit (MSB, b8) to the least significant bit (LSB, b1).
