BRUSSELS — Radio Frequency Systems (RFS) will be showing a series of 'WiMAX-ready' tower-top solutions that comprise truly global electrical-tilt WiMAX antennas, to be unveiled at the Mobile World Congress 2008 exhibition in Barcelona.
Designated the Optimizer APXVx56516 antenna series these products form part of a broad and growing IEEE 802.16 WiMAX-compliant solution set — a set that includes antennas, fibre-to-the-tower top technologies, RF conditioning, and in-building solutions.
Comprising both variable and remote electrical-tilt versions, the dual-polarised WiMAX antenna series is available in two wideband variants — 2.3 to 2.7 GHz (APXV256516-x) and 3.3 to 3.8 GHz (APXV356516-x). As a result, the latest antenna series supports the widest range of sub-bands currently allocated for WiMAX applications across Europe, the Americas and the Asia-Pacific region.
In support of emerging WiMAX network capacity enhancement strategies, side-by-side 'quad-polarised' versions of the entire Optimizer APXVx56516 series are also planned for launch later in 2008.
The WiMAX electrical-tilt antennas provide RF performance for which the RFS Optimizer family is renowned — infinite beam tilt adjustment from zero to ten degrees, upper side-lobe suppression of better than 18 dB across the entire tilt range, and null fill of the first lower null. Global reach is achieved with just two models, dramatically cutting inventory requirements and costs, and improving deployment efficiencies.
The RFS WiMAX remote-tilt antenna solution (APXVx56516-RET) features a unique antenna control unit (ACU) that is discretely built within the antenna radome. The onboard ACU allows precision WiMAX antenna beam tilt control either locally (from the tower base), or remotely from the network's operations and maintenance centre (OMC). Connectivity to the antenna beam tilt-control system is achieved via an Antenna Interface Standards Group v2.0-compliant interface at the base of the antenna.
