Datagram Transport Layer Security (DTLS)
A communications protocol providing security to datagram-based applications by allowing them to communicate in a way designed to prevent eavesdropping, tampering, or message forgery.
Development Kit (DK)
A hardware development platform used for application development.
DK
Constrained Application Protocol (CoAP)
A specialized web transfer protocol for use with constrained nodes and constrained networks in the Internet of Things.
CoAP
E-UTRAN Node B (eNB)
The hardware that is connected to the mobile phone network that communicates directly wirelessly with mobile handsets (
UE), like a base transceiver station in GSM networks. Also known as
Evolved Node B.
Enhanced Machine Type Communication (eMTC)
A low-power wide area network radio technology standard developed by 3GPP to enable a wide range of cellular devices and services.
eMTC
Firmware-Over-The-Air (FOTA)
A firmware update performed remotely over the air (OTA).
FOTA
Global Navigation Satellite System (GNSS)
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.
GNSS
Hypertext Transfer Protocol Secure (HTTPS)
An extension of the Hypertext Transfer Protocol (HTTP) used for secure communication over a computer network.
HTTPS
Internet of Things (IoT)
Physical objects that are embedded with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems of the Internet or other communications networks.
IoT
Internet Protocol (IP)
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.
IP
Lightweight M2M (LWM2M)
A device management protocol developed by OMA SpecWorks designed for sensor networks and the demands of a machine-to-machine (M2M) environment.
LWM2M
Long-Term Evolution (LTE)
A wireless broadband communication standard for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies.
LTE
Low-power Wide Area Network (LPWAN)
A type of wireless telecommunication wide area network designed to allow long-range communications at a low bit rate among things, such as sensors operated on a battery.
LPWAN
LTE-M
An open standard that is most suitable for medium throughput applications requiring
low power, low latency, and/or mobility, like asset tracking, wearables, medical, POS, and
home security applications. Also known as Cat-M1.
Message Queueing Telemetry Transport (MQTT)
A lightweight, publish-subscribe network protocol that transports messages between devices.
MQTT
Mobile Network Operator (MNO)
A provider of wireless communications services that owns or controls all the elements necessary to sell and deliver services to an end user.
MNO
Over-the-Air (OTA)
Refers to any type of wireless transmission.
OTA
Pre-shared Key (PSK)
A password authentication method, a string of text, expected before a username and password to establish a secured connection. Also known as a shared secret.
PSK
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
System in Package (SiP)
Several integrated circuits, often from different technologies, enclosed in a single module that performs as a system or subsystem.
SiP
Transmission Control Protocol (TCP)
One of the main protocols of the Internet protocol suite. TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network.
TCP
Transport Layer Security (TLS)
A cryptographic protocol that provides end-to-end security of data sent over a
computer network.
TLS
User Datagram Protocol (UDP)
One of the core members of the Internet protocol suite that lets computer applications send messages (datagrams) to other hosts on and Internet Protocol network. Prior communications are not required to set up communication channels or data paths.
UDP
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
