The capabilities of service composition aim to support service chaining and instantiation, specification interpretation, service brokering and execution, and context- aware and dynamically adaptive service composition. The purpose of the Software Defined Quantum Communication SDQC standard is to define a classical interface to quantum communication devices that permits these devices to be reconfigured to implement a variety of protocols and measurements.
This standard defines the Software-Defined Quantum Communication SDQC protocol that enables configuration of quantum endpoints in a communication network in order to dynamically create, modify, or remove quantum protocols or applications. The standard defines a set of quantum device configuration commands that control the transmission, reception, and operation of quantum states. These device commands contain parameters that describe quantum state preparation, measurement, and readout. This standard facilitates the rapid realization of the Tactile Internet as a 5G and beyond application, across a range of different user groups.
Additionally, this standard provides the groundwork upon which the Tactile Internet will be formed. To this end, this standard provides a baseline for a pioneering range of further standards that will be created under this working group realizing the key necessary technical capabilities of the Tactile Internet. This standard defines a framework for the Tactile Internet, including descriptions of various application scenarios, definitions and terminology, functions, and technical assumptions.
This framework prominently also includes a reference model and architecture, which defines common architectural entities, interfaces between those entities, and the mapping of functions to those entities. The Tactile Internet encompasses mission critical applications e. This standard defines haptic codecs for the Tactile Internet TI. These codecs address TI application scenarios where the human is in the loop i.
The standard defines perceptual data reduction algorithms and schemes for both closed-loop kinesthetic information exchange and open-loop tactile information exchange communication. These codecs are designed such that they can be combined with stabilizing control and local communication architectures for time-delayed teleoperation.
Further, the standard also specifies mechanisms and protocols for the exchange of the capabilities e. This standard enhances the situational awareness of aircraft to communicate in an ad hoc aerial network. This standard defines air-to-air communications for self-organized ad hoc aerial networks. The communications and networking standards are independent of the type of network Wireless or Cellular or other and are applicable to manned and unmanned, small and large, and civil and commercial aircraft systems.
This standard introduces more automation in networking by means of an SDN bootstrapping procedure that can be used regardless of the networking and connectivity service environments for the sakes of proper interoperation between SDN computation logic instance s and the managed resources networking, storage, CPU , virtualized or not, that will be involved i. This standard covers interoperability, collaboration and autonomous operation of an Internet of Things IoT system with computing required for context building, security, access control, data storage, data aggregation and ability to choose different cloud and application service providers.
Furthermore, this standard defines how an end user is able to securely provision, commission and decommission the devices. This standard leverages existing applicable standards and is complementary to architectural frameworks defined in broader IoT environments. This standard defines an architectural framework for the Internet of Things IoT , including descriptions of various IoT domains, definitions of IoT domain abstractions, and identification of commonalities between different IoT domains.
The architectural framework for IoT provides a reference model that defines relationships among various IoT verticals e. It also provides a blueprint for data abstraction and the quality "quadruple" trust that includes protection, security, privacy, and safety. The reference architecture covers the definition of basic architectural building blocks and their ability to be integrated into multi-tiered systems.
The reference architecture also addresses how to document and, if strived for, mitigate architecture divergence. This standard leverages existing applicable standards and identifies planned or ongoing projects with a similar or overlapping scope. This document comprises recommended practices for the measurement of antenna transmitting and receiving properties.
Throughout this standard it may be assumed that the antenna to be measured can be treated as a passive, linear, and reciprocal device. Therefore its radiation properties can be measured in either the transmitting or the receiving mode.
Many of the test practices described can, however, be adapted for use in the measurement of antenna systems containing circuit elements that may be active, nonlinear, or nonreciprocal. For these cases there is no simple relationship between the antenna systems transmitting and receiving properties.
Therefore measurements shall be performed for the mode or modes in which the antenna system has been designed to be used. A fundamental property of any antenna is its radiation pattern. The measurement of radiation patterns in an antenna test facility is discussed. The design of antenna test facilities is described along with instrumentation requirements for the proper operation of the antenna facility, directions for the evaluation of an existing range, and the operation of ranges is discussed. For each direction of space, the radiation pattern is characterized by amplitude, phase, and polarization.
From the measurement of these parameters, gain, directivity and radiation efficiency can be determined. Power transfer from generator to antenna is controlled by the input impedance to the antenna. This important parameter frequently limits the useful bandwidth of the antenna.

A method adopted in other standards is presented and discussed for its applicability to the various test facilities described. Throughout this standard, attempts are made to discuss measurement techniques as thoroughly as is practicable. However, in general step-by-step procedural descriptions have been avoided.
References are provided which are illustrative of measurement techniques and in which details may be found. The standard provides terms and definitions used in the context of electromagnetic wave propagation relating to the fields of telecommunications, remote sensing, radio astronomy, optical waves, plasma waves, the ionosphere, the magnetosphere, and magnetohydrodynamic, acoustic, and electrostatic waves. Some obsolete terms and definitions will be removed. The language used for some already existing terms will be refined. The standard will also include some additional terms that are commonly accepted in these fields.
Near-field test practices for the measurement of antenna properties are described in this document and near-field measurement practices for the three principal geometries: cylindrical, planar, and spherical are recommended. Measurement practices for the calibration of probes used as reference antennas in near-field measurements are also recommended. The key feature of these standards is the definition of a TEDS. The TEDS is a memory device attached to the transducer, which stores transducer identification, calibration, correction data, and manufacture-related information.
The goal of is to allow the access of transducer data through a common set of interfaces whether the transducers are connected to systems or networks via a wired or wireless means. This standard defines a method for data sharing, interoperability, and security of messages over a network, where sensors, actuators and other devices can interoperate, regardless of underlying communication technology.savilertatu.tk

The standard utilizes the advanced capabilities of the XMPP protocol, such as providing globally authenticated identities, authorization, presence, lifecycle management, interoperable communication, IoT discovery and provisioning. Descriptive meta-data about devices and operations will provide sufficient information for infrastructural components, services and end-users to dynamically adapt to a changing environment.
Key components and needs of a successful Smart City infrastructure will be identified and addressed. The purpose of this standard is to present minimum performance requirements for those precision connectors used at RF, microwave and millimeter-wave frequencies. It introduces the performance requirements needed to standardize precision pin and socket type connectors.
The standard presents updated test methods to utilize automatic vector network analyzers VNAs along with current state-of-the-art concepts in connector technology, and displays specification values from individual connector types in a connector summary table. A very important utility of this standard is that it serves as a user's guide. One unique feature of this standard is that it embodies the general requirements, definitions, measuring methods, and other pertinent information into one document for all eight standard connector types while making use of the "detail specifications" information from each connector type for standardization into separate Annexes.

The scope of this standard is to specify coaxial connectors for precision electrical measurements for use at RF, microwave and millimeter-wave frequencies. Current state-of-the-art coaxial connectors are covered by the Standard. This document provides recommended practices for the determination of measurement uncertainty for digitally modulated signals used in wireless communications. Applications include the determination of uncertainty in system-level distortion metrics that are used in wireless communication standards, such as error vector magnitude.
Recommended best practices are provided for each metric. This Recommended Practice defines common terms in large-signal vector network analysis. Some fundamental terms used in small-signal vector network analysis that are also commonly used in large-signal vector network analysis are covered as well.
