Other Broadband Wireless Technologies WiMAX

WiMAX and Other Broadband Wireless Technologies WiMAX is not the only solution for delivering broadband wireless services. Several proprietary solutions, particularly for fixed applications, are already in the market. A few proprietary solu-tions, such as iBurst technology from ArrayComm and Flash OFDM from Flarion (acquired by QualComm) also support mobile applications. In addition to the proprietary solutions, there are standards-based alternative solutions that at least partially overlap with WiMAX, particularly for the portable and mobile applications.

In the near term, the most significant of these alternatives are third-generation cellular systems and IEEE 802.11 based WiFi systems. In this section, we compare and contrast the various standards-based broadband wireless technologies and high-light the differentiating aspects of WiMAX.
