RFS unveils ‘UMTS-on-AWS’ RF control at CTIA Wireless 07

A new end-to-end solution set that allows precise remote control and monitoring of tower-top RF components will be unveiled by wireless technology group, Radio Frequency Systems (RFS) at CTIA Wireless 2007. Fully compliant with the latest revision of the open communications standard of the Antenna Interface Standards Group (AISG), the new RFS suite addresses the unique challenges facing carriers in the new advanced wireless services (AWS) band, particularly those planning to deploy UMTS services in the new band.

“AWS broadband wireless networks--most notably UMTS networks--will be particularly demanding from an operational and optimization perspective,” said RFS Director of Marketing and Product Management, Larry Heisler. “It’s for this reason that our new AISG v2.0-compliant tower-top control and monitoring solution set is the cornerstone of our AWS-band solution set. As the AISG v2.0 is ratified by the ‘Third Generation Partnership Project’ (3GPP), the RFS AISG v2.0-compliant suite is ideal for UMTS deployments.”

The new RFS AISG version 2.0-compliant solution set makes it possible for carriers to accurately control and monitor tower-top components either locally (from the tower base), or remotely from the network’s operations and maintenance centre (OMC).The suite frees the end-user from the inherent restrictions associated with proprietary control and monitoring systems. This ensures the fastest and most cost-efficient installations--both greenfield deployments and mature network retrofits.

A true end-to-end solution, RFS’s new AISG version 2.0-compliant product suite comprises all key antenna line elements--the control network interface (CNI), a selection of tower-mount amplifiers (TMA), an antenna control unit (ACU) and a modem bias-tee.

The new RFS AISG version 2.0-compliant solution set includes RFS’s innovative Network Element Manager (NEM) software--considered to be one of the most intuitive and user-friendly software interface for an AISG version 2.0 solution set. The NEM software has been specifically designed for ease-of-use and ensures fast-track network installation, commissioning and troubleshooting. Step-by-step instruction provides uncomplicated access to a vast library of antenna line device (ALD) diagnostics and settings, such as antenna tilt, azimuth adjustment and real-time ALD system diagnostics. As a result, abnormalities such as loose connections, power loss and antenna over-travel, can be detected and corrected before they impact on network QoS.

The suite also boasts the industry’s most compact and high-performance AISG version 2.0-compliant ACU. Its lightweight construction (only 470 grams/16 ounces) helps reduce tower loading, while its small footprint and sleek design minimizes environmental impact. Performance-wise, it provides a continuous torque of 0.15 NM and boasts an angular resolution of better than 0.2 degrees. The new ACU also features a non-volatile on-board memory, ensuring that all programming data is retained if the CNI has to be replaced or DC power is disconnected.

The new RFS 19-inch rack format CNI-P incorporates a power distribution unit (PDU), which supports up to six TMAs and 12 ACUs across three sectors. Individual ACU and TMA units are linked in a ‘daisy-chain’ configuration, with the CNI’s networks capable of supporting up to a total of 18 ALDs over a maximum cabling length of 100 meters (330 feet). The CNI itself provides three separate RS485 field output ports (one per antenna sector). CNI backhaul connectivity is achieved via either point-of-protocol (PPP), SNMP or DHCP protocols, with either fixed or dynamic IP address management.
