About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Keysight Secures New Test Case Validations for Narrowband Non-Terrestrial Networks Standard

  • Test case validations include transmitter and receiver, demodulation, and radio resource management for narrowband internet of things over non-terrestrial networks
  • Validations support certification testing at GCF Recognized Test Organizations
  • Record number of new test cases secured at Conformance Agreement Group #78 meeting, including RedCap radio resource management for single receiver and inter-radio access technology with EUTRA

Keysight Technologies, Inc. (NYSE: KEYS) has validated new conformance test cases for 3rd Generation Partnership Project (3GPP) Release 17 (Rel-17) standards for non-terrestrial networks (NTN) using narrowband internet of things (NB-IoT) technology. Available through the Keysight RF/RRM DVT and Conformance Toolset, the validated test cases were obtained at the Conformance Agreement Group (CAG) #78 meeting of the Global Certification Forum (GCF).

The convergence of terrestrial and non-terrestrial networks is a key component of the telecommunications industry’s goal of achieving global coverage, enabling new use cases and ubiquitous mobile connectivity. NB-IoT over NTN extends service to use cases requiring non-continuous data connections with low power consumption, while maintaining sufficient throughput, for diverse applications such as supply chain tracking and two-way messaging.

The new NB-IoT NTN conformance test case validations cover transmitter and receiver, demodulation, and radio resource management (RRM). The RF/RRM DVT and Conformance Toolset ensures mobile devices perform as expected on a live mobile network and is an approved test platform for device certification at GCF and PTCRB supporting a variety of frequency bands.

These test case validations also enable Keysight to support certification testing at GCF Recognized Test Organizations (RTO). The test cases are managed through the Keysight ATLAS Test Management Center, the company’s new framework for automated acceptance testing.

Keysight is at the forefront of NTN conformance solutions with the S8711A Test Application Toolset and UXM 5G, featuring a built-in channel emulator that emulates satellite orbits to test and certify devices in real-world conditions. The company has validated test cases for Skylo’s Rel-17 NB NTN certification program and recently demonstrated satellite handovers in Low Earth Orbit constellations, using UXM 5G and PROPSIM at Mobile World Congress.

In addition, Keysight expanded its portfolio of validated test cases to other crucial 3GPP Release 16 (Rel-16) and Rel-17 areas to achieve a record number of new validations in a single meeting. Notable test case validations included RRM RedCap for single receiver and inter-radio access technology with EUTRA.

Muthu Kumaran, General Manager for Keysight’s Device Acceptance Solutions, said: “Industry standards and reference certification programs play a pivotal role in expanding technology adoption. Keysight‘s NTN solutions, which enables NB-IoT NTN certification testing in GCF Recognized Test Organizations, are empowering the industry to advance mixed terrestrial and non-terrestrial connection scenarios with confidence by adhering to globally recognized standards. We look forward to continuing our support for the wireless industry in the realm of NTN through our comprehensive test solutions.”
