A metadata record is a file of information, usually presented as an XML document, which captures the basic characteristics of a data or information resource.

A short-range wireless band commonly used in wireless technologies such as Wi-Fi, Bluetooth, and ZigBee. 2.4GHz has a relatively slow data throughput in comparison to other networks.

Global Navigation Satellite System (GNSS) is a satellite system that is used to pinpoint the geographic location of a user's receiver anywhere in the world. Each of the GNSS systems employs a constellation of orbiting satellites working in conjunction with a network of ground stations.

The Russian global navigation satellite system with a constellation made of 24 satellites orbiting Earth.

Global Positioning System (GPS) is a global navigation satellite system that uses at least 24 satellites, a receiver, and algorithms to provide a location, velocity, and time synchronization for air, sea, and land travel.

4G LTE is a 4G wireless communications standard developed by the 3rd Generation Partnership Project (3GPP) that's designed to provide up to 10x the speeds of 3G networks for mobile devices.

In contradiction to brownfield, a greenfield project is a one where no consideration of previous systems is needed; thus, already existing standards can be ignored.

An open-source software framework for distributed storage and distributed processing of very large data sets. An application can be broken down into numerous small parts, called fragments or blocks, that can be run on any node in the cluster.

The running of Hadoop in the Cloud requires no local hardware or IT infrastructure. The service is typically elastic, allowing the adding or removal of nodes depending on user needs.

The Hadoop Distributed File System (HDFS) is designed to store very large data sets reliably, and to stream those data sets at high bandwidth to user applications.

Also referred to as Haptics or “touch feedback,” haptic technology applies tactile sensations to human interactions with machines. The simplest example is the actuator that vibrates a cell phone, but more advanced haptics can detect the pressure applied to a sensor, affecting the response.

A hard fork (or hardfork), as it relates to blockchain technology, is a radical change to a network's protocol that makes previously invalid blocks and transactions valid, or vice-versa.

Head-Mounted-Display is a display device, worn on the head or as part of a helmet that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD).

A term coined by design academics Anthony Dunne and Fiona Raby, Hertzian Space refers to the hidden electromagnetic environment generated by the increasing number of wireless devices.

A heterogeneous network (HeNet) is a network connecting computers and other devices with different operating systems and/or protocols. HetNets allow mobile operators to better utilize their data networks’ capacity.

High-Speed Downlink Packet Access (HSDPA) is an enhanced 3G mobile-telephony communications protocol in the High-Speed Packet Access family, also dubbed 3.5G, 3G+, or Turbo 3G, which allows networks based on Universal Mobile Telecommunications System to have higher data speeds and capacity.

High Speed Packet Access (HSPA) is a wireless access technology designed for increasing the capacity of Internet connectivity from 3G mobile terminals/

An improvement made to UMTS to enable faster uploading of data from devices, increasing capacity and throughput while reducing delay. The specifications for HSUPA are included in the Universal Mobile Telecommunications System Release 6 standard published by 3GPP.

Homomorphic encryption is a form of encryption that allows computations to be carried out on ciphertext, thus generating an encrypted result which, when decrypted, matches the result of operations performed on the plaintext.

Hotspot (Wi-Fi) is a physical location where people may access to the Internet, typically using Wi-Fi technology, via a wireless local-area network (WLAN) using a router connected to an Internet service provider.

Human augmentation is used to refer to digital technologies that enhance a person’s cognitive, productivity, or physical capabilities. An example is using active control systems to create limb prosthetics with characteristics that can exceed the highest natural human performance.

Human-computer interaction (HCI) is the study of how people interact with computers and to what extent computers are or are not developed for successful interaction with human beings.

Another way of expressing the Quantified Self-concept, the Human Internet of Things (HIoT), refers to the collection and optimization of physiological data from sensors applied to humans, generally with wearable tech.

A user-interface is consisting of hardware and software that lets a person send requests/commands to a machine. Typically HMIs are meant to make it as easy as possible for a person to control a machine with little difficulty.

Hyperautomation involves the application of advanced technologies, including AI and machine learning, to increasingly automate processes and augment humans. Hyperautomation extends across a range of tools that can be automated, but also refers to the sophistication of the automation

Hyperscale computing is a distributed computing environment in which the volume of data and the demand for certain types of workloads can increase exponentially yet still be accommodated quickly in a cost-effective manner.

An application protocol for distributed, collaborative, hypermedia information systems. Hypertext Transfer Protocol (HTTP) is the foundation of data communication for the World Wide Web.

A set of systems that includes a source system and a collection of consuming systems. Each system in a given identity domain uses the same unique identifier. The operational server enables the integration of information across multiple identity domains.

Processes and policies involved in managing the lifecycle and value, type, and optional metadata of attributes in identity known in a particular identity domain.

The Identity of Things (IDoT) is an area of endeavor that involves assigning unique identifiers (UID) with associated metadata to devices and objects (things), enabling them to connect and communicate effectively with other entities over the Internet.
