  • Reduce Tower Climbs, Get Ready for C-RAN and Carve the Path to 5G with CPRI Panel Solutions from RFS

    RFS’ new Common Public Radio Interface (CPRI) panel enables easy RF over CPRI testing at the bottom of the tower, reducing the need for unnecessary tower climbs, to minimize maintenance costs and overall OPEX for customers.

  • Nuclear Power Plant Tests DAS

    An initial test of a distributed antenna system (DAS) shows promise for addressing nuclear power plant coverage challenges.
    Nuclear power plants need reliable wireless communication systems for efficient management and maintenance, but their complex, super-reinforced concrete construction makes it difficult to get RF signals to and through most areas within. RFS and SOLiD developed and tested a DAS system for a decommissioning plant in Florida as a proof-of-concept to overcome these challenges and enable wireless communications inside the plant. RFS’ higher-order mode suppression technique, which allows its radiating cable to have no stop bands from 698 MHz to 2.7 GHz, was a significant factor in the system’s success. For a nuclear plant, this capability is needed to accommodate a high-performance, future-proof design and fewer shadows to enable LTE technology for data management. The radiating cable provided a uniform distribution of RF energy over the entire distance of the cable, improving coverage in all frequencies. The feasibility test was so successful that further testing will now be conducted in active power plants for future deployment.

  • The Effect of Low Quality Antennas on Network Backhaul

    In today’s world, people often overlook the details that allow us to take advantage of the technology presented to us.  For instance, the antenna is usually taken for granted, yet this passive component is vital to the success of your entire network.  This paper describes the effects of numerous quality variables on the performance of a microwave antenna, and provides insight into the long-term consequences of using a low-cost/ poor quality antenna.  Additionally, it demonstrates the effect of operators’ preference for low-cost antennas without considering the possible detriments to their quality of service.  Various suppliers offer low-quality antennas at reduced prices that can backfire on performance, ultimately weakening your network and business.

  • Eileen Januszkiewicz, RFS Commercial Product Manager of Cables, contributed to Microwaves & RF’s recent report, "Passive Components Punch Through Walls"

    Due to their superior power-handling capability, passive components are an extremely important aspect of a high performance distributed antenna system.  Throughout the article, RFS addresses how its passive components go above and beyond when it comes to satisfying the imperative need for consumer connectivity through their power dividers/combiners, directional couplers, hybrid couplers and other passive devices. This special report, written by Microwaves & RF, takes a look at some of these passive component solutions designed to meet the increasing demand for communication and connection wherever people may go.

  • Know Your Options: Future-Proof Antennas for the US Repack

    As the North America broadcast market embarks on the spectrum repack later in 2016 there are many decisions to be made. One of those is antenna technology selection. The US market has traditionally opted for the narrowband antenna known as a slotted pole or pylon. There are many advantages in choosing a pylon antenna, but also several limitations, including lack of flexibility for future channel changes. Broadband antennas provide advantages, especially those using variable polarization technologies. Furthermore,  broadband slot antennas, pylon alternative antennas, and master panel antennas can be used by multiple broadcasters to share costly site infrastructure and significantly reduce operating costs, while adding flexibility of site redundancy for very high availability networks.  This white paper explores the pros and cons of these antenna technologies.

    NBC 5 shows how it is preparing for the US repack with the installation of an RFS PEPL-28 antenna at Cedar Hill, Texas this week.

  • How Future-Proof Antenna Systems Help Broadcasters in the U.S. Television Spectrum Repack

    The U.S. broadcast spectrum repacking program is imminent, and challenges for broadcasters transitioning to new channel assignments are many. Nick Wymant, CTO Broadcast at RFS, delivered a presentation at NAB2016 evaluating some of those challenges and providing insightful recommendations for broadcasters’ infrastructure solutions. Find out how future-proof antenna systems can help stations through the conversion.

  • Technical Analysis: Flexible Feed Design

    This RFS White Paper highlights RFS’ “flexible feed” architecture of its CompactLine® and CompactLine® Easy antennas. The flexible, easily-modified design lowers re-design costs and allows quicker response to changes in today’s complex networks including  several uncertainties that exist in designing network backhaul systems. Sometimes parameters such as frequency range of operation are not confirmed until the last minute. This can potentially cause delays in finalizing specifications of passive components such as antennas, and hence, delays in overall system installation.
