When Tower Design Meets the Real World: How Antenna Selection Must Adapt During the Site Development Phase of a New Tower Build

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

This article is Part 2 in a series that Antenna Systems & Technology has invited me to write about how antenna selection evolves over the course of a new wireless tower project, impacted by factors that emerge during each of the three phases of these projects:

  • The initial RF design and antenna selection phase
  • The site development phase, which includes site Engineering, leasing and permitting; and
  • The final phase of tower construction and testing Continue reading

The Many Benefits Of Testing Your Antenna

Glenn Robb, Principal Engineer
Antenna Test Lab Co.

Your customers must succeed for you to succeed. Customers expect your system or products to perform their best at all times. In this RF world, that means your antennas have to “shine”! Not only will great antennas contribute to joint vendor/customer success, they help your company rise above the competition of mediocre or even bad antenna competition. Continue reading

What Does “5G” Mean for IoT?

Chris Anderson, Vice President of Engineering
Taoglas

The universal goals of 5G are to decrease latency, provide at least a 10 times speed increase over LTE, and service up to a million Internet of Things (IoT) devices per square kilometer. To meet these goals,5G networks will look a lot different than any existing 3G or 4G network. Deploying technology solutions in the millimeter wave spectrum has completely different requirements and challenges from anything currently commercially deployed. Continue reading

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. (see Figure 1) Continue reading

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?

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.
