Patterns of Success: Antenna Patterns to Play a Key Role in WiMAX Success
As the wireless data market grows, deploying wireless technologies with high spectral efficiency will be of paramount importance. The more effectively systems can manage signal interference, the higher the cell capacity, and the more profitable the system. In short, the degree to which WiMAX succeeds will depend in large part on the ability to minimize channel interference. This positions the base station antenna system as critical to WiMAX long-term success. Going forward, antenna pattern shaping and interference control will play a significant role in successful WiMAX deployments. This paper examines some of the key causes of signal interference in the WiMAX environment and discusses techniques being employed and developed to provide RF engineers with greater ability to improve spectral efficiency.
