Internet of Things (IOT) Glossary
Whatever the growth forecasts, connected objects are already widely present in our daily lives, considerably changing our uses. The world of the Internet of Things is vast and involves different but complementary concepts. What is Artificial Intelligence? What is a Network? What does Healthcare mean? When are we talking about a Connected Home? What is the purpose of a Cloud? What does Interoperability mean? What does Big Data mean? To answer your questions, Legrand offers you a glossary containing all the definitions of terms related to the IoT.
AI (Artificial Intelligence)

The process of assuring that all systems and components of a project or solution are designed, installed, tested, operated, and maintained according to the operational requirements of the project owner or final client.
Note: A commissioning process may be applied not only to new also to existing units and systems subject to expansion, renovation
A communications system quantity. They have 7 layers and the focus is usually on two functions, the network and the application.
• Network Layers: The network (layers 1-6) defines the physical properties and how data is transferred. (An everyday example of a network layer is the telephone network which include cell phones, land lines, VoIP as network layers.)
o Common networks for IoT include:
• IP standards (Ethernet, Wi-Fi, Cellular, Long range RF networks such as SigFox, and Thread)
• Other non-IP networks examples include the serial network RS-485 (used for BACnet MS/TP)
o These layers require a language (application) to communicate before they can be leveraged.
• Application Layer: The application layer is the language on the network. (An everyday example of Application Layer for telephones is French / English / Spanish.)
o Common Applications for IoT include: BACnet, KNX, Zigbee, Dot Dot Dot, Weave and IoTivity.
• BACnet for example can run on RS-485, Wi-Fi and Thread.

Thing that makes something possible.
Consumer services and devices/apps allow people to track, control and monitor their gas/electricity consumption.
Federated Identity (Login)
The means of linking a person’s identity and attributes, stored across multiple distinct identity management systems. (Such as single sign-on (SSO), in which a user's single authentication ticket, or token, is trusted across multiple IT systems or even organizations. SSO is a subset of federated identity management, as it relates only to authentication and is understood on the level of technical interoperability.
Fog (An IoT Architecture)
An architecture approach that uses a collaborative multitude of end-user clients or near-user edge devices to carry out a substantial amount of temporary storage, communication, control, configuration, measurement and management.
Gateway (An IoT Enabler)
An IoT gateway is a device that enables machine-to-machine communication by connecting appliances in the home, workplace or smart city to networks.
Devices or applications related to the fitness and wellness sector that seamlessly integrate with each other to create a strong customer experience.
Technologies and/or services that focus on monitoring and protecting the home as well as the remote and automated control of doors, windows, blinds and locks, heating/air conditioning, lighting and home appliances, and more.
Information Access Management (IAM)
The security disciple that enables the right individuals to access the right resources at the right times for the right reasons.
Things that allow connected devices to connect permanently and securely within buildings.
Intelligent LED Lighting
Refers to lighting that has automated or mechanical abilities beyond those of traditional lighting, utilizing DC power and control delivered through partial or complete Ethernet based structured cabling, for improved efficiency and tailored user experience.
The Internet of Things is a network of uniquely identifiable endpoints (or “things”) that contain embedded technology to sense, collect, communicate and, exchange data locally or with external environments, without human interaction affecting our daily life.
Combination of network Infrastructure & active devices to support IoT environment: e.g. PoE, WAPs, gateways, edge devices, etc…
Protocols Include Network and Application layers (All 7 layers) Examples include: IoTivity, Zigbee, KNX, ZWave, BACnet MS/TP, EnOcean, Echelon, KNX-IP.
• Note I: Applications can run on different networks to form a protocol
• Note II: Primary benefit of IP and Iotivity is no translation required (eg. English to Spanish)
• Note III: Some solutions today use a layer and the network layer
• Note IV: Application translation requires driver development which requires constant updating
IP Convergence refers to the capability of the Internet to act as a single foundation for various functions that traditionally had their own platforms.
Responsible for transmitting the data collected by the physical layer to different devices.
The internet communication layer that enables the entity to communicate with their device, and sometimes enables devices to communicate with each other.
Familiar home networking technologies (high bandwidth/high power consumption), such as Multimedia over Coax Alliance (MoCA), Ethernet, Wi-Fi, Bluetooth, as well as 3G and Long Term Evolution (LTE), are complemented with low-power consumption networking standards for devices and sensors that require low bandwidth and consume very little power, such as thermostats.
