Glossary

A digital modulation technique used for signals in which four bits are modulated at once by selecting one of 16 possible combinations of carrier phase shift and amplitude.

A command used to control the modem.

A digital modulation technique used for signals in which one bit is modulated by selecting one of two possible carrier phase shifts with a 180-phase difference.

A single-frequency electromagnetic wave that can be modulated in amplitude, frequency, or phase to convey information.

The last one-digit number of the International Mobile (Station) Equipment Identity (IMEI) code used for error detection.

A non-cellular radio standard included as part of the 5G standards by the ITU.

A manufactured product undergoing testing.

A unique number embedded on a microchip for identifying mobile devices.

A satellite navigation system with global coverage. The system provides signals from space transmitting positioning and timing data to GNSS receivers, which use this data to determine location.

A digital signal pin that can be used as input, output, or both. It is uncommitted and can be controlled by the user at runtime.

A unique code consisting of 14 digits and a check digit for identifying 3GPP-based mobile devices.

A unique code consisting of 16 decimal digits and two software version digits for identifying 3GPP-based mobile devices.

The network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.

A seven-bit coded character set for information exchange.

In a radio receiving system, an electronic amplifier that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio.

A wireless broadband communication standard for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. 

A dedicated control interface for the RF front-end subsystem. MIPI Alliance

A narrowband technology standard with longer range, lower throughput, and better penetration in, for example, cellars and parking garages compared to LTE-M. NB-IoT is most suitable for static, low throughput applications like smart metering, smart agriculture, and smart city applications. Also known as E-UTRAN (NB-S1), Cat-NB1, and Cat-NB2.

A 3GPP communication system that delivers wireless connectivity using satellites, drones, or high-altitude platforms instead of ground-based infrastructure.

Memory that can retrieve stored information even after having been power-cycled.

A type of non-volatile memory that permits data to be written to memory only once.

A type of digital transmission and a method of encoding digital data on multiple carrier frequencies.

A device used to increase the transmit power level of a radio signal.

A board that connects electronic components.

A modem firmware version used in the device manufacturing phase.

A form of modulation used to represent an analog signal with a binary signal where the switching frequency is fixed, and all the pulses corresponding to one sample are contiguous in the digital signal.

A digital modulation technique used for signals in which two bits are modulated at once, selecting one of four possible carrier phase shifts.

The smallest unit of resources that can be allocated to a user.

A unique six-digit number part of the IMEI code identifying each equipment within each Type Allocation Code (TAC).

The level of signal power compared to the level of noise power, often expressed in decibels (dB).

Part of the IMEI code identifying the revision of the software installed on a mobile device.

A card used in User Equipment (UE) containing data for subscriber identification.

Several integrated circuits, often from different technologies, enclosed in a single module that performs as a system or subsystem.

A microchip that integrates all the necessary electronic circuits and components of a computer or other electronic systems on a single integrated circuit.

The initial eight-digit part of an International Mobile (Station) Equipment Identity (IMEI) code used for identifying the model of a mobile phone.

Any device used by an end-user to communicate. The UE consists of the Mobile Equipment (ME) and the Universal Integrated Circuit Card (UICC).

A unique address for identifying each slave device in an RFFE (RF Front-End) system.

A card used in User Equipment (UE) containing data for subscriber identification.
