New White Paper from Fujitsu Microelectronics, Cisco, Describes Benefits of Adaptive Beamforming in WiMAX Networks

    Beamforming Significantly Improves Indoor Penetration of Broadband Signals
    by Increasing WiMAX Network Range and Capacity

    SUNNYVALE, Calif., July 28 /CNW/ -- Fujitsu Microelectronics America,
Inc. (FMA), a global leader in WiMAX SoC technology and solutions, has
co-authored with Cisco a new white paper entitled "Beamforming Boosts the
Range and Capacity of WiMAX Networks." The paper, which describes how adaptive
beamforming can magnify the advantages of a WiMAX network, is available at
    WiMAX is an affordable technology for transferring large amounts of data
reliably and with high throughput. Adaptive beamforming magnifies these
advantages by increasing both the range and capacity of a WiMAX network at a
relatively low implementation cost. In fact, beamforming reduces both the
capital and operating expenses for WiMAX implementations by decreasing the
number of base stations and relay stations needed.
    Beamforming also significantly improves indoor penetration of wireless
broadband signals by mapping the optimal downlink path for signals arriving by
multiple pathways from a subscriber device. The result is a high
signal-to-noise ratio, which enables the use of higher orders of modulation,
with transmission and decoding using 64QAM or other high-order symbols. The
reduced interference and higher signals made possible with beamforming
translate into faster data downloads and better overall service.
    Both Fujitsu and Cisco are committed to using beamforming technology in
WiMAX networks and in their WiMAX products as well.
    The paper also describes the basics of multiple in/multiple out (MIMO)
technology, which can improve wireless data communications. Finally, the paper
reviews the history of beamforming and similar technologies, and offers a
basic explanation of beamforming alternatives with details on antenna
