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.

DOCOMO Develops Solution to Create High-frequency Mobile Cells By Placing Small Plastic Antenna on Dielectric Waveguide Cable

TOKYO, Jan 17, 2022 - (JCN Newswire) - NTT DOCOMO, INC. announced today that it has developed an antenna system capable of creating a high-frequency mobile communication cell when a small (roughly one cubic centimeter) piece of plastic is placed on top of a dielectric waveguide. The solid plastic cube serves as an antenna by creating a "leak" from the cable to propagate signals up to several tens of meters. DOCOMO successfully tested the system with an ultra-high-frequency 60 GHz radio signal, similar to those expected to be used in future 6G networks.

DOCOMO envisions its simple, low-cost solution being used to create instant mobile environments in indoor areas not reachable with highly directional high-frequency signals propagated by outdoor base stations.

This system, named "Drop-n-Prop Antenna," takes advantage of the physical phenomenon of radio waves leaking (propagating) from the contact point created by placing ("dropping") a small piece of plastic on top of a dielectric waveguide carrying the signal.

In the trial, DOCOMO constructed a communication area by running a rod-shaped dielectric waveguide made of polytetrafluoroethylene into an indoor area that was inaccessible to external mobile signals. The waveguide was embedded in a length of polystyrene-foam board with one side barely exposed to allow contact with antennas. Multiple communication cells were created simultaneously by placing antennas along various parts of the waveguide. Signal coverage and direction were controlled by changing the material, shape and positioning of the antennas.

Both millimeter waves (28 GHz) for 5G and higher frequencies (60 GHz, etc.) expected to be used for 6G travel in very straight (rectilinear) lines. It is difficult for such waves to reach devices not in a base station's direct line of sight, or if the signals are blocked by surrounding obstacles (walls, equipment, etc.). DOCOMO's simple, low-cost antenna system being announced today merely requires a rod-shaped dielectric waveguide to be run into an area and then embedded in the floors, walls, ceilings, furniture or work surfaces. Communication areas can be constructed easily and unobtrusively in offices, factories, etc. and reconfigured quickly and flexibly just by moving the antenna(s) as required.

The new antenna system also will help to lower energy use by efficiently propagating signals to desired areas only, thereby eliminating wasteful usage of power to propagate signals in areas where communication is not required.

DOCOMO will begin verifying a system using 28 GHz 5G radio signals in the first half of fiscal 2022 starting this April, aiming to introduce a commercial version of its new antenna system as soon as possible.

DOCOMO will demonstrate the new Drop-n-Prop Antenna system during New windowDOCOMO Open House 2022, which is being held online from today for three days (January 17-19).
