What is claimed to be one of the world's first 'WiMAX-ready' adaptive antenna systems has been released by Radio Frequency Systems.
Specially designed to meet the needs of emerging IEEE 802.16 worldwide interoperability for microwave access (WiMAX) broadband wireless data networks, the W4A series antenna system features beam-pattern shaping and is part of a growing WiMAX suite from RFS.
Available in 2.5 and 3.5 GHz models (W4A25-90ANV and W4A35-90AN), at the heart of each system is a four-element 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.
