Amid the flurry of activity and hype surrounding mobile TV, STAY CONNECTED steps back and takes a look at the various network models and technology platforms that have emerged as contenders. 10 Wireless coverage where everybody WINS Whether standing on the thirtieth floor of a skyscraper or seated in a subway, today’s consumers want wireless access whenever and wherever they are. RFS Wireless Indoors Solutions provides the solutions. RF conditioning gets a Latin feel With the global demand for network optimization components on the rise, RFS launches its fourth RF conditioning manufacturing facility in Embu, São Paulo, Brazil. 15 6 13 Base station antenna’s evolution of integration The ubiquitous wireless base station antenna takes the next step in its evolution—one that sees the ‘antenna’ become an ‘antenna system’, with integrated functionality that transforms it far beyond its passive roots. It’s a fact of modern life—many of us these days are looking to shed extra pounds or kilograms to feel the benefits. It’s exactly the same in the RF industry. Losing a few pounds on infrastructure has real ‘lifestyle benefits’ for carriers, broadcasters, tower owners and managers, system integrators and installers. Weight—or lack of it—has significant total life-cycle cost implications. Reduced weight at the tower top is a core Radio Frequency Systems’ Value Message, and an area where we clearly lead the market. RFS offers the wireless world the lightest weight solutions—pound-for-pound, ounce-for-ounce, kilo-for-kilo. Interestingly, it has been a cornerstone objective of our RF solutions almost since our company began. In the early 1950s, RFS presented the wireless market with the world’s first corrugated outer foam-dielectric coaxial cable. Manufactured using our patented continuous welding technique, the ‘new’ RFS flexible feeder system liberated installers of the time from an RF transmission system that was extremely heavy and labor-intensive to install. The RFS corrugated transmission line relieved towers and civil structures of an unnecessary load, dramatically reducing the labor efforts required to complete the transmitter to tower-top link. Shedding kilograms on the end-to-end RF solution has very real, very quantifiable capex and opex impacts to those paying the check. Consider these: Tower space rentals—The vertical real-estate sector bases a large portion of its tariffs on the weight, rather than the volume or total number, of the components mounted at the tower-top. In many areas of North America, for example, tower-top ‘components’ attract zero weight tariff for total weights up to 20 pounds (9 kilograms), and then a sliding scale applies for weights above that. Carriers pay dearly for those extra pounds—every month. Support infrastructure—The weight cost passes down the line to those who own and maintain the actual infrastructure supporting the RF components. Every kilogram counts— transmission line, antennas, RF conditioning components, brackets and so on. More kilograms mean more steel, more welding more bracketing, bracing and supporting. Labor and installation—In some parts of the world, the difference between 22 kilograms and 19 kilograms (48 pounds and 42 pounds) is the difference between two men up the tower versus one. That’s twice the labor costs during installation and maintenance. With these costs a major element of modern capex and opex, an opportunity to save on associated labor is all-important. Logistics and transport—And it’s not just the at-site handling that matters. Logistics and transport are often the great ‘hidden cost’ of any roll-out strategy and one thing is for certain— consignment weight is the biggest factor in determining the bottom line on logistics. Stéphane Klajzyngier Radio Frequency Systems President Across its entire solution set, RFS has demonstrated that weight really matters. We offer the market’s lightest weight solution in every sector. Consider these examples: CELLFLEX L-Series—Our new aluminum outer corrugated foam-dielectric transmission line is the lightest RF transmission line solution available today. Weighing in at just 330 grams per meter (3.5 ounces per foot), CELLFLEX L-Series is less than two-thirds of the weight of competing transmission lines. It’s a world’s-first, and a lightweight solution for the wireless generation. Lightweight tower solutions—Courtesy of our towers division group, CGTI Towers, RFS is able to offer some of the lightest self-supporting tower structures in the world. These include innovative tower designs that boast extremely high wind- and weight-loading capacities, yet weigh a fraction of legacy galvanized steel tower solutions. Lightweight polymer filters—RFS was the first on the market with silver-plated polymer filters. Slashing the weight of tower-top RF conditioning technologies by around 50 percent, this RFS innovation also provides the highest RF performance. Twin tower-mount amplifiers (TMAs)—The recently launched twin PCS-band TMAs for the US market demonstrate the weight advantage of our advanced RF conditioning designs. For this market, we’re providing twice the functionality in a standard weight and sized package. Low-profile/low wind-load microwave solutions— With microwave antennas, the very nature of the EDITORIAL antenna means that wind load equates to the effective ‘weight’ of the antenna on the tower. Our ultra-low profile SlimLine and CompactLine solutions provide a microwave antenna that is almost invisible to wind. Ingenious design of the feed system has allowed us to develop the slimmest profile antenna with ‘beyond industry standard’ operational and survival windspeed rating. The end result? Less effective ‘weight’ on the supporting tower means less cost to the end-user. In some parts of the world, the ‘light-weight’ title is something of a putdown—in the RF solutions world, it’s quite the opposite. RFS has worn the ‘lightweight leader’ badge proudly for over half a century. For more than five decades we have led the market in the development of minimal weight end-to-end RF solutions. Our long-term goal is to continue reducing, trimming and cutting back on component weight. At RFS, we are taking— and will continue to take—the weight off our customers’ shoulders.

Optimizer Rooftop: Cleverly compact— powerful performance Striking the optimal balance between aesthetics, RF performance and capex/opex, RFS’s new Optimizer Rooftop is set to transform urban rooftops the world-over. The new Optimizer Rooftop is a unique all-in-one solution comprising base, mast, tri-sector antenna cluster and RF cabling. It strikes at the heart of the modern network manager’s most vexing problem—the visual impact requirements that often prove to be the ‘Achilles’ heel’ of urban site acquisition and site renewal negotiations. Available now in selected regional markets, the Optimizer The Optimizer Rooftop has been developed with the site crew in mind, permitting easy assembly with simple tools and a two-person crew. (155 miles per hour) and mast deflection of less than one-degree at 160 kilometers per hour (100 miles per hour). Total lifecycle cost reduction The Optimizer Rooftop reduces the total lifecycle cost of the rooftop base station, by providing premium value to all stakeholders.
