Triple-Band Antennas

Radio Frequency Systems (RFS) has introduced the APXVBLL20X-C and APXVBLL20X-C-I20 models of its RF X-TREME Triple-Band Antenna, RFSwhich facilitate triple-band site upgrades for reduced cell interference in high traffic areas.  BLL RF X-TREME antennas can be used for multiple bands such as LTE 700, LTE 800, Digital Dividend 2, CDMA, GSM, DCS, UMTS and LTE 2.6.  With the RF X-TREME portfolio, RFS provides the capacity of three full-band antennas by orienting them side by side to achieve high gain and optimal performance in a single package. Using the entire antenna length for every band instead of the traditional method of stacking antennas on top of one another allows operators to move from a dual-band antenna to a triple-band antenna of the same length and maintain similar gain levels.  Providing full-band coverage on every port enables operators to now implement 4xRx and 4xMIMO on any of the higher frequency bands, enhancing cell-edge performance with fewer base stations – which is particularly effective for LTE advanced. www.rfsworld.com

Ultra-Broadband Triple-Band Antennas

Radio Frequency Systems (RFS) has introduced the APXVBLL20X-C and APXVBLL20X-C-I20 models of its RF X-TREME Triple-Band Antenna. The latest ultra-broadband antennas facilitate triple-band site upgrades for reduced cell interference in high traffic areas. BLL RF X-TREME antennas can be used for multiple bands such as LTE 700, LTE 800, Digital Dividend 2, CDMA, GSM, DCS, UMTS and LTE 2.6.

With RF X-TREME, RFS provides the capacity of three full-band antennas by orienting them side-by-side to achieve high gain and optimal performance in a single package. Providing full-band coverage on every port enables operators to implement 4xRx and 4xMIMO on higher frequency bands for cell-edge performance with fewer base stations.

The aerodynamic BLL models support 694-2690MHz frequency bands. They are triple-band cross-polarized with three arrays (6 ports), 1×694-960 / 2×1695-2690. The radome design reduces wind load and minimizes tower loading. RFS triple-band antennas offer broad variable tilt range from 0-10 degrees, beneficial in dense areas, while maintaining 28dB isolation premium performance.

Variable electrical downtilt enhances precision for controlling intercell interference; tilt is remotely adjustable according to AISG/3GPP standards. The antennas offer integrated RET, manual overdrive and tilt indicator to streamline installation and ease-of-use. Integrated RET serial numbers on the antenna radome ease on-site commissioning and secure remote mapping from OMC. www.rfsworld.com

AWS-3 Antennas

RadioFrequencySystemsShowcase0315 (2)Radio Frequency Systems (RFS) offers products to help carriers support the new AWS-3 frequency bands. All RFS 65-degree core antenna models are already compatible with AWS-3, and AWS-3 support will be extended to every other RFS antenna model. RFS’ product portfolio for AWS-3 includes new models of filters, diplexers and tower-mounted amplifiers to include AWS-3 paired spectrum, 1755 MHa to 1780 MHz and 2155 MHz to 2180 MHz, all with the same RF performance. The products feature lightweight, low insertion loss, IP67 Class protection and a new triplexer with DC sensing. www.rfsworld.com

Tower-Mounted Amplifiers

Radio Frequency Systems has announced the availability of tower mounted Amplifiers (TMAs) for the 700 MHz ABC-block, 700 MHz upper-C block, 700 MHz public safety LTE spectrum and AWS-PCS dual band with integrated 700/850 MHz diplexer. As operators roll out Voice-Over-LTE (VoLTE) services, they need to deliver the high-quality voice services no interruptions in service. This can be accomplished by optimizing the uplink signal from the user device with tower-mounted amplifiers, ensuring seamless VoLTE coverage while maintaining the high data throughput needed to deliver an optimal user experience.

Tower-mounted amplifiers are increasingly being deployed in low-band frequencies, such as 700 MHz, because the LTE is uplink-limited — and VoLTE underlines this limitation even further. The LTE system takes advantage of the added uplink gain provided by a TMA, reducing the transmitted power of all mobile devices in the cell. This reduces the overall interference that mobile devices generate in the uplink spectrum. www.rfsworld.com

 

Plenum-Rated Omni-directional Antennas

PIM-rated, LTE-ready antennas from Radio Frequency Systems can be concealed for improved aesthetics while meeting stringent building codes. The I-ATO3-698/2700 Series of plenum-rated, PIM-certified omni-directional antennas is designed for broadband in-building distribution of LTE, GSM, CDMA, PCS, 3G, Wi-Fi and WLAN services.

The I-ATO3 series can be used in in-building passive DAS applications. It has an optimized design to avoid passive intermodulation because of its plenum-rated, helically corrugated low-loss pigtail cable with copper outer conductor and factory attached N female connector. The I-ATO3 series also features a PIM rating  of 150 dBc @ 2x20W, and the virtually non-existent upper side lobe reduces interference with cells on other floors, delivering better patterns and superior gain and directivity. www.rfsworld.com
