The Ripple Effect: Impacts of Antenna Selection on the Stages of a New Wireless Tower Build

John Keating, P.E., EVP of Market Operations
Centerline Solutions

Every decision has consequences. Like ripples in the surface of a pond that travel outward, each choice influences everything that comes afterward. These ripples intersect with those created by other decisions, forming new patterns in the process. Standing on the shore of a pond and watching the water’s surface probably isn’t the first thing that comes to mind when you think of wireless tower projects, but it’s an apt metaphor for the way antenna-related decisions throughout a tower project impact how the process unfolds and reshapes the next phase of the project.

Selective Deposition of Silver Layers via Jet Metal Technology for the Production of Antennas

Koen Staelens, Business Development Manager
Jet Metal Technology

Since the start of the company in 2007, Jet Metal Technologies focused its efforts to place its unique in-line metallization technology by spraying on the market for decorative applications in cosmetic and spirit bottle applications. In such decorative applications a layer stack consisting of a base coat varnish (15-20 µm), a thin silver layer (~80 nm) and a protective top coat varnish (15-20 µm) is used. The many advantages of the Jet metal technology led to great success as nearly 20 industrial lines in Europe and North & Middle America were installed and produce annually millions of metallized spirit bottles, scent bottles and caps for big players like Coty, Hennessy, L’Oréal, Louis Vuitton, Procter and Gamble and Pernod-Ricard.

Aperture Tuning, the Best Technique for Closed Loop Tuning

Paul Tornatta, VP RF Systems and Antenna Engineering
Cavendish Kinetics, Inc.

Modern Smart Phones are packed with useful features. In order to maximize the user experience, the performance of the radio must be optimized at all times. Antenna Aperture Tuning is a method used by all top-tier Smart Phone makers for optimizing the antenna performance across several frequency bands of operation. The next step in antenna optimization is closed loop tuning. In closed loop tuning, some performance metric (often antenna reflection coefficient) is used to change the response of the RF front-end to dynamically compensate for variations in usage including compensating for the detuning effects of the users head and hands during phone operation.  Dynamic tuning to compensate for head and hand effects is not a new concept. Most RF engineers believe the best way to implement closed loop tuning is with an impedance matching network, but if aperture tuning, not impedance matching, is the best way to tune an antenna, then why not use aperture tuning for closed loop tuning as well?

Sinclair Technologies Helps NAV Canada Safely Move Millions of Aircraft

Michel Gagnon, Sinclair Technologies
Tammy St-Amand, NAV Canada

Who is NAV Canada?
NAV CANADA is Canada’s Air Navigation Service Provider (ANSP) managing 12 million aircraft movements a year for 40,000 customers over 18 million square kilometers. They are the world’s second-largest ANSP by traffic volume. Created in 1996 through the combined efforts of commercial air carriers, general aviation, the Government of Canada, as well as their employees and their unions, NAV CANADA is the world’s first fully privatized civil air navigation service provider.

The Ongoing IoT Conundrum: Who’s Going to Pay?

Dermot O’Shea, Co-Founder and Joint CEO 
Taoglas

The adoption of Internet of Things (IoT) technologies has certainly been on the rise, and just about every industry—in every corner of the globe—has made strides forward with IoT projects. We’re seeing Smart City initiatives pop up around the world, Smart Metering projects mandated by governments, healthcare initiatives developed that drive adoption of IoT devices, and so on.

High Density, Low Profile Connectors Benefit from New Breed of Spring-Loaded Pin

Plastronics

For decades, connector manufacturers have relied on traditional spring-loaded, or pogo-style pins, to provide highly compliant, reliable interconnections. Although expensive, these highly compliant pins are used to connect batteries to docking stations, antennas to PCBs, for rugged, high-shock and vibration applications, or to compensate for floating heights and uneven mating surfaces.

Spotlight on New HyperStacking Ground Penetrating Radar Technology

Jeffrey Feigin, PhD, GSSI

Ground-penetrating radar (GPR) is an electromagnetic imaging technique that allows users to see beneath the surface through soil, pavement, concrete, ice, and even water. GPR is widely used for utility mapping, concrete inspection, forensic investigations, geological surveys, and archaeology. Regulatory agencies place stringent power emission limits on GPR equipment to prevent disruption to other technologies that share the same spectra, for example, wireless communications and global positioning systems.  Continue reading
