RFS launches global WiMAX adaptive antenna solution at 3GSM

The next in the series of Radio Frequency Systems’ ‘WiMAX-ready’ adaptive antenna systems--a truly global wideband suite--will be unveiled at the 3GSM World Congress 2007 exhibition in Barcelona. The new global W4AxxW antenna solution 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.

RFS’s new wideband W4AxxW solution set streamlines and simplifies global WiMAX deployment strategies. Comprising just two models--the W4A25W-90ANV (2.3 to 2.7GHz) and the W4A35W-90ANV (3.3 to 3.8GHz)--the new wideband antenna series supports the widest range of sub-bands currently allocated for WiMAX applications across Europe, the Americas and the Asia-Pacific region. Achieving global reach with just two models, the new RFS W4AxxW dramatically cuts inventory requirements and costs, and improves deployment efficiencies.

Purpose-built to meet the exacting needs of emerging WiMAX broadband wireless data networks, RFS’s new wideband W4AxxW series antenna system features precision beam-pattern shaping. The wideband W4AxxW 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 mobile platforms,” said Radio Frequency Systems (RFS) Area Product Manager Rémi Deniel. “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 wideband W4AxxW 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.”

The heart of each W4AxxW 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.

The RFS WiMAX exhibit at 3GSM World Congress 2007 will also include a sneak preview of its ‘in-development’ WiMAX remote radio head (RRH). Designed to provide transmit output power of 4 watts per channel, the new unit boasts one of the industry’s lightest and most compact form factors. With a total package volume of just 10 liters (one-third cubic foot) and weighing only 10kg (22 pounds), the new RFS WiMAX RRH can be either pole-mounted at the tower top, or wall-mounted at tower base.

Based on an open industry standard, the RFS WiMAX RRH will offer premium performance, compact size and reliability. The new RRH is expected to be commercially available at end-2007/early-2008.

RFS’s growing suite of WiMAX-compliant base station solutions will be exhibited at 3GSM World Congress 2007: Hall 2, Stand C34, Venue Fira de Barcelona, Montjuic, Barcelona, Spain, 12 to 15 February 2007.
