Glossary

The glossary contains terms and acronyms that are used in this document.

Development Kit (DK)

A hardware development platform used for application development.

DK

International Mobile (Station) Equipment Identity (IMEI)

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

IMEI

General-Purpose Input/Output (GPIO)

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.

GPIO

Global Positioning System (GPS)

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

GPS

Integrated Development Environment (IDE)

A software application that provides facilities for software development.

IDE

Low-Noise Amplifier (LNA)

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

LNA

MCUboot

A secure bootloader for 32-bit microcontroller units, which is independent of hardware and operating system.

Near Field Communication (NFC)

A standards-based short-range wireless connectivity technology that enables two electronic devices to establish communication by bringing them close to each other.

NFC

nRF Cloud

Nordic Semiconductor's platform for connecting IoT devices to the cloud, viewing and analyzing device message data, prototyping ideas that use Nordic Semiconductor chips, and more. It includes a public REST API that can be used for building IoT solutions. See nRF Cloud (nrfcloud.com).

Personal Identification Number (PIN)

An optional security feature in mobile devices used for identifying a user. PIN is a numeric code which must be entered each time a mobile device is started.

PIN

Personal Unblocking Key (PUK)

A digit sequence required in 3GPP mobile phones to unlock a Subscriber Identity Module (SIM) that has disabled itself after an in correct personal identification number has been entered multiple times.

PUK

Software Development Kit (SDK)

A set of tools used for developing applications for a specific device or operating system.

SDK

SEGGER Embedded Studio (SES)

A cross-platform Integrated Development Environment (IDE) for embedded C/C++ programming with support for Nordic Semiconductor devices, produced by SEGGER Microcontroller.

SES

Subscriber Identity Module (SIM)

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

SIM

System in Package (SiP)

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

SiP

System on Chip (SoC)

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

SoC

User Equipment (UE)

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

UE

Universal Integrated Circuit Card (UICC)

A new generation SIM used in UE for ensuring the integrity and security of personal data.

UICC

Universal Serial Bus (USB)

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.

USB
