RFS proves AISGv2-ready at 3GSM Barcelona

At the 3GSM World Congress 2007 in Barcelona, leading wireless technology group, Radio Frequency Systems (RFS), will unveil a new end-to-end solution set that allows remote control and monitoring of tower-top RF components. Fully compliant with the latest revision of the open communications standard of the Antenna Interface Standards Group (AISG), the new RFS suite empowers carriers to cost-effectively optimize their networks in real-time.

The new RFS AISG version 2-compliant product suite frees the end-user from the inherent restrictions associated with proprietary control and monitoring systems, ensuring fast-track network retrofits and greenfield deployments. The solution makes it possible for carriers to control and monitor tower-top components either locally (from the tower base), or remotely from the network’s operations and maintenance centre (OMC).

A true end-to-end 3G solution, RFS’s new AISG version 2-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 day-to-day, hour-to-hour--and even minute-to-minute--network RF monitoring and optimization that the RFS AISGv2-compliant solution provides is essential in today’s competitive wireless world,” said David Kiesling, RFS Global Product Manager Wireless Infrastructure Solutions. “This is particularly crucial in advanced broadband wireless data solutions, along with mature 2G networks.”

The new RFS AISG version 2-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 solution set.

The new RFS 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-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.
