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 Validation for First 3GPP Release 16 16/32 Transmitter Performance Enhancement Test Cases

  • Validations cover single and multiple precoding matrix indicator test cases for 16 and 32 element transmitters operating on the frequency-division duplexing and time-division duplexing bands
  • First test cases for 3GPP Release 17 Enhanced Power Saving covering reductions in network paging and the increase of RedCap device discontinuous reception cycles validated
  • Validation achieved at Conformance Agreement Group #77 meeting hosted by Keysight in Malaga, Spain

Keysight Technologies, Inc. (NYSE: KEYS) gained approval for the industry’s first 3GPP Release 16 (Rel-16) 5G New Radio (NR) single and multiple precoding matrix indicator (PMI) test cases for 16 and 32 element transmitters operating on the frequency-division duplexing (FDD) and time-division duplexing (TDD) bands. The validated test cases, which are for use with Keysight's 5G network emulation conformance test platform (TP168), were obtained at the Conformance Agreement Group (CAG) #77 meeting of the Global Certification Forum (GCF) hosted by Keysight in Malaga, Spain during January.

Networks based on 5G NR standards support multi-antenna technologies known as MIMO, which improve spectral efficiency and enhance communication. To implement multi-antenna systems, enhanced precoding techniques are applied to the transmitter to map data into the different transmit antennas. The optimal precoding depends on a PMI Codebook value reported by the device, which makes the choice from several precoding options based on its own channel measurements.

As part of Rel-16, the 3GPP added new test cases to validate device performance in multi-antenna systems. Keysight S8705A RF/RRM test solution is the first to gain validation for these new tests, which require unprecedented fading resources to emulate 16 and 32 transmitter connections to use equipment (UE) with 2 and 4 receivers.

Keysight also achieved the following achievements supporting Release 17 (Rel-17) Enhanced Power Saving and RedCap features:

  • Validation of test cases verifying UE support of a function that reduces the number of times a device interacts with the network, in order to extend the battery life of devices using the S8705A RF/RRM test solution.
  • Validation of test cases ensuring RedCap devices support the Rel-17 increase in the extended discontinuous reception (eDRX) cycle, which is the duration of time a device is in sleep mode in order to extend battery life. This was completed with the Keysight S8704A Protocol Conformance Toolset and activates the RedCap Rel-17 eDRX GCF work item.

Muthu Kumaran, General Manager of Keysight's Device Acceptance Solutions, said: "Enhancing connection performance is a priority for network operators to deliver a better quality of service to final users. Multi-antenna systems are possible with NR and now the first approved tests are brought into the market by Keysight to ensure device’s performance is thoroughly tested. Additionally, validations supporting Rel-17 Enhanced Power Saving features are crucial to drive advancements in 5G NR Rel-17 for commercial 5G NR and RedCap devices market introduction."
