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 Gains First Validation of 5G New Radio FR1 1024-QAM Demodulation Test Cases

  • 1024-QAM test case validations for the FR1 frequency band support the throughput performance enhancements needed for enhanced Mobile Broadband services
  • 3GPP Release 16 Demodulation Performance Enhancement test cases also validated
  • Validations confirmed at Conformance Agreement Group #79 meeting

Keysight Technologies, Inc. (NYSE: KEYS) gained validations for the industry’s first 5G NR FR1 1024-QAM demodulation test cases based on the 3GPP TS 38.521-4 test specification. The validated test cases, which are for use with Keysight’s 5G network emulation conformance test platform (TP168), were secured at the Conformance Agreement Group (CAG) #79 meeting of the Global Certification Forum (GCF) in July.

Developed by 3GPP, 5G New Radio (NR) radio access technology delivers the performance needed to support enhanced Mobile Broadband (eMBB), which provides end users with better multimedia experiences through higher data rates, increased bandwidth, improved reliability, and lower latency. eMBB services can be improved further in the 5G FR1 frequency range by using 1024-QAM modulation, which significantly enhances spectral efficiency and data throughput rates.

Keysight achieved these test case validations through the addition of 1024-QAM support on the E7515B UXM 5G Test platform, which is available as a software-only upgrade to existing users. By achieving this validation milestone, Keysight enables users to thoroughly validate their devices, ensuring full compliance before their products are launched in the market.

Keysight also achieved test case validation for WI-528 Release 16 NR Demodulation Performance Enhancements, which is now open for certification following Keysight’s validations in several frequency bands. This work item is supported by multiple operators, with test cases checking the incremental downlink performance when a transmitter is configured based on a precoding matrix index reported by the device instead of using a random value.

Muthu Kumaran, General Manager of Keysight’s Device Acceptance Solutions, said: “Keysight remains dedicated to helping chipset and device manufacturers verify and obtain certification for their New Radio devices supporting the most advanced 3GPP Release 16 and Release 17 features. Following extensive collaboration with our customers, we are pleased that the Global Certification Forum has officially recognized our validation status for 1024-QAM. These test cases enable the rigorous testing of NR devices, ensuring their successful entry into the market with confidence.”
