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.

Knowles Releases New TWS Reference Design with Best-In-Class Music Experience and Advanced Features

Incorporating results of new listening study, KN2 reference design delivers audio quality consumers demand

Knowles Corporation (NYSE: KN), a market leader and global provider of advanced micro-acoustic microphones and speakers, audio solutions, and high-performance capacitors and RF products, today announced the availability of KN2, the first True Wireless Stereo (TWS) reference design tuned to the Knowles Preferred Listening Response Curve for the best music listening experience. KN2 features a state-of-art hybrid dual speaker system paired with an advanced Bluetooth system-on-chip (SoC) to deliver superior High Definition (HD) audio and active noise cancellation (ANC) performance along with other advanced features.

Consumer expectations for HD audio are at an all-time high, placing more pressure on OEMs across markets to deliver premium sound performance with robust connectivity and long-wear comfort. The hybrid dual speaker system consists of a dynamic speaker for warm, robust bass combined with a Knowles balanced armature (BA) tweeter for delicate, precise treble. Together they deliver a full-bodied listening experience. The small form factor of the system enables a comfortable fit without compromising sound quality and range.

Knowles recently released its Preferred Listening Response Curve for earphone design. Knowles began by analyzing 200 Billboard Hot 100 songs to determine the treble content of popular music, then performed double-blind listening tests on a range of consumers to evaluate their preferred treble response when listening to that music. Knowles’ study revealed that treble response beyond 10 kHz is essential for delivering the best and most satisfying music listening experience. Designing and tuning an earphone that matches the high frequency response of the Knowles Preferred Listening Response Curve is expected to consistently provide a highly satisfactory end user experience and solicit high ratings from consumers. KN2 is the first earphone reference design to be tuned to the curve, optimizing treble performance to bring breadth and life to music.

KN2 also incorporates a robust collection of must-have TWS features into its small footprint. It includes the Qualcomm QCC5144 BT SoC with the aptX codec and aptX Adaptive for robust, low-bit rate, low-latency HD audio and hybrid ANC. Also, within the earbuds are multiple Knowles SiSonicTM MEMS microphones to enable voice call algorithms for enhanced noise canceling performance. This compact, comfortable and high-performance reference design accelerates the time-to-market and alleviates design challenges for TWS manufacturers.

“Consumer expectations for TWS performance are high and now technology is primed to deliver HD audio wirelessly. OEMs across all market segments – from luxury brands to household names to new entrants – are growing more ambitious and competing to deliver feature-rich devices with the best sounding audio,” said Jon Kiachian, Vice President and GM of Knowles Hearing Health Technologies. “Knowles knows the audio business beyond just components. KN2 is designed from over 75 years of audio performance expertise to enable manufacturers to bring wireless HD audio to the masses and deliver the functionality, range and performance customers crave, without the hurdles of product design.”

The KN2 reference design will be available for purchase on Digi-Key and Mouser in Q4 2022. For more information visit www.knowles.com/KN2.
