The AIS-compliant antenna products open the door to remote electrical tilt (RET) technology, as well provide the benefits of real-time network optimization. According to RFS, the AISG-compliant suite is an end-to-end solution comprising RET components, tower mounted amplifiers (TMA) and bias tee. At its heart is the Optimizer RT, an RET system that uses the RFS antenna control unit (ACU) to perform remote and accurate electrical tilt operations, obviating the need for direct antenna access. It is retro-fittable onto all RFS Optimizer antennas with variable electrical tilt.

In addition, the company has launched a new AISG control network interface (CNI-P), which is designed to provide connectivity between active equipment in the mast, such as ACU and TMA, and both on-site (local PC) and off-site (LAN, WAN or the Internet) locations. Using the CNI-P, operators can adjust antenna tilt from the network management center, as well as extract a wide range of manufacturing parameters, alarms, and status data from all tower mounted AISG devices. The CNI-P incorporates a power distribution unit (PDU) for supporting up to three RFS dual TMAs and nine ACUs.
