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 portal (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.
