A white paper on benefits of adaptive
beamforming in WiMAX Networks
Fujitsu Microelectronics and Cisco have published a new
white paper named "Beamforming Boosts the Range and
Capacity of WiMAX Networks." explaining how adaptive
beamforming can magnify the advantages of a WiMAX network.
Adaptive beamforming is adopted in WiMAX networks to increase
both the range and capacity of a WiMAX network. Beamforming
saves capital and operating expenses of WiMAX implementations
by decreasing the number of base stations and relay stations
needed.
Beamforming technology selects better signal paths for
WiMAX receivers operating indoors fitted on laptops and
mobile phones by mapping the optimal downlink path for signals
arriving by multiple pathways from the subscriber device.
Both Fujitsu and Cisco said, they 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 elements.
