LoRa

LoRa: Proprietary radio modulation technology for LPWAN (Low-Power Wide-Area Network) used by LoRaWAN.
LoRaWAN: Low-Power Wide Area Network (LPWAN) specification. LoRaWAN defines the communication protocol and system architecture for the network.
Packet forwarder: The packet forwarder is a program running on the host of a Lora gateway that forwards RF packets received by the concentrator to a server and emits RF packets that are sent by the server.
CPF: Common Packet Forwarder issued from Kerlink for Wirnet iBTS and iFemtoCell gateways.

Network

IMEI (International Mobile Equipment Identity): Unique number that identifies mobile phone sets.
IMSI (International Mobile Subscriber Identity): Unique number, usually fifteen digits, associated with Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) network mobile phone users. The IMSI is a unique number identifying a GSM subscriber.
MCC (Mobile Country Code): Number used in combination with an MNC to uniquely identify a mobile subscribers network.
MNC (Mobile Network code): Number used in combination with an MCC to uniquely identify a mobile subscribers network.
AT commands: Specific command language. The command set consists of a series of short text strings which can be combined to produce commands for operations such as dialing and changing the parameters of the connection.
Ofono: Ofono is a free software project for mobile telephony (GSM/UMTS) applications.
ConnMan: ConnMan is an internet connection manager for embedded services running the Linux operating system.

VPN (Virtual Private Network): A Virtual Private Network extends a private network across a public network. A VPN secures the private network, using encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
IPsec: IPsec is a suite of protocols designed to authenticate and encrypt all IP traffic between two locations. IPsec can be deployed to implement VPNs.
strongSwan: strongSwan is an Open Source IPsec-based VPN solution for Linux and other UNIX based operating systems.
OpenVPN: OpenVPN is an open-source software application that implements virtual private network (VPN).
Optee: OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. The main design goals for OP-TEE are: Isolation from the non-secure OS, Small footprint and Portability.

Systemd: systemd is a software suite that provides an array of system components for Linux operating systems. It is a suite of basic building blocks for a Linux system, providing aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic.
SNMP (Simple Network Management Protocol): Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
MIB (Management Information Base): Database used for managing the entities in a communication network. Most often associated with SNMP, the term is also used more generically.
IPK: Extension of OPKG packages.
OPKG (Open PacKaGe management): Lightweight package management system.
