One of the world’s first ‘WiMAX-ready’ adaptive antenna systems will be unveiled by wireless technology leader, Radio Frequency Systems (RFS), at the 3GSM World Congress 2006 exhibition in Barcelona. The new adaptive antenna is part of RFS’s broad and growing suite of IEEE 802.16 worldwide interoperability for microwave access (WiMAX)-compliant solution set–a set which will include: antennas, RF conditioning solutions, and ‘WiMAX-ready’ in-building solutions.
Purpose-built to meet the exacting needs of emerging WiMAX broadband wireless data networks, the new RFS W4A series antenna system features precision beam-pattern shaping. The new RFS W4A series antenna system provides network managers with a powerful tool to ensure optimal data throughput and a reduction in overall cell-to-cell interference across the WiMAX network.
“WiMAX technology promises us a new era in broadband wireless connectivity across fixed, nomadic and, eventually, mobile platforms,” said RFS WiMAX Business Development Director, Martial Guillaume. “It also poses new challenges on the network management and RF fronts–most particularly as subscriber demand increases and greater network capacity is required. The new W4A series WiMAX adaptive antenna system specifically addresses these challenges, by providing the precision beam-pattern shaping required to dynamically support the evolving needs of the WiMAX network.”
Available in 2.5 and 3.5-GHz models (W4A25-90ANV and W4A35-90ANV), the heart of each W4A series adaptive antenna system is a four-element antenna array. Flexible beam-pattern tailoring is achieved by applying phase and amplitude modulation to each element. As a result, the shape of the beam-pattern can be modified in response to changing subscriber traffic and interference sources, or as part of a longer-term strategy to ensure optimal data throughput, spectrum use or network capacity.
Commercial launch of the new RFS W4A series WiMAX antenna is planned for the second half of 2006. RFS will unveil the new W4A series adaptive antenna at 3GSM World Congress, Hall 2, Stand F30, Venue Fira de Barcelona, Montjuic, Barcelona, Spain, 13 to 16 February 2006.
