Introduction
Having gained tremendous momentum over a number of years, WiMAX is now widely viewed as a leading candidate for fourth-generation
(4G) wireless data communication. Because WiMAX is based on Internet Protocol (IP), the technology builds on principles that
have proven versatile and cost-effective in the Internet. Compared to traditional 3G cellular networks, WiMAX offers a more
affordable technology for transferring large amounts of data with high throughput.
A technology known as adaptive beamforming can magnify this WiMAX advantage considerably. At a relatively low implementation
cost, beamforming improves both the range and capacity of a WiMAX network. In fact, beamforming reduces capital and operating
expenses for WiMAX implementations by minimizing the number of base stations needed in a network.
Fujitsu and Cisco are strongly committed to the use of beamforming in WiMAX networks, and both companies use beamforming in
their WiMAX products. This white paper outlines the operation and advantages of beamforming.
