Glossary

A register used to prevent read and write access to all CPU registers and memory-mapped addresses.

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

A manufactured product undergoing testing.

A method in mobile communication to conserve the battery of a mobile device by turning the RF modem in a sleep state.

A development platform used for application development.

A register used to block NVMC ERASEALL and CTRL-AP.ERASEALL functionality.

A method to conserve the battery of an IoT (Internet of Things) device by allowing it to remain inactive for extended periods.

A satellite-based radio navigation system that provides its users with accurate location and time information over the globe.

A semiconductor chip consisting of fabricated transistors, resistors, and capacitors.

A measurement channel definition.

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

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 Cat-NB1.

The relation of the Signal-to-Noise Ratio (SNR) in the device input to the SNR in the device output.

Refers to any type of wireless transmission.

A feature introduced in 3GPP Release 12 to improve battery life of IoT (Internet of Things) devices by minimizing energy consumption. The device stays dormant during the PSM window.

A board that connects electronic components.

A modem firmware version used in the device manufacturing phase.

3GPP specified measurement channels for RF performance verification.

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

Circular polarization in which the electric field vector rotates in a right-hand sense with respect to the direction of propagation.

A register used to prevent read and write access to all secure CPU registers and secure memory-mapped addresses.

A standard two-wire interface for programming and debugging Arm® CPUs.

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

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

A number of 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.

A procedure initiated by the UE when moving to a new tracking area in the LTE (Long-term Evolution) system.

A hardware device for asynchronous serial communication between devices.

A new generation Subscriber Identity Module (SIM) used in UE for ensuring the integrity and security of personal data.

An industry standard that establishes specifications for cables and connectors and protocols for connection, communication, and power supply between computers, peripheral devices, and other computers.

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

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