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 and CTTL Complete First CTIA MIMO Over-the-Air Dynamic Channel Model Test System Validation

  • Collaboration implements and validates first dynamic MIMO over-the-air channel model for the 5G New Radio FR1 frequency band
  • Solution benchmarks realistic user equipment performance of different manufacturers and chipset vendors

 

Keysight Technologies, Inc. (NYSE: KEYS) has built the first MIMO over-the-air (OTA) dynamic channel model test and user equipment (UE) performance validation system with China Telecommunication Technology Labs (CTTL) based on CTIA requirements for the 5G New Radio (NR) FR1 frequency band.

UE suffers from performance degradation in real-world use due to various propagation channel effects. These issues are addressed by optimizing UE hardware and software design and validating them under real-world conditions. To do this, design engineers need consistent, reliable, and repeatable digital twins that can emulate the real-world channel effects.

Keysight and CTTL collaborated to meet this need by integrating the first CTIA-compliant MIMO OTA test system with a dynamic channel model validation test. The new validation tool is based on Keysight’s OTA Emulation Solutions that emulates real world environments to perform OTA testing for UE with multiple antennas. The Keysight solution includes:

Xu-Dong An, Director of OTA and LBS Division at CTTL, said: “The new 5G dynamic MIMO test solutions further expand our ability to serve a wide range of customers. With this addition, CTTL-Terminals is poised to provide comprehensive services for research, development, testing, and certification across the entire industry.”

Peng Cao, Vice President and General Manager at the Keysight Wireless Test Group said: “We are pleased to provide the first test system in the world for MIMO OTA with dynamic channel model validation. Keysight will continue driving the development of industry standards as a leading contributor in CTIA.”
