Technological advances in antenna steering and beam width control have allowed accurate antenna orientation adjustments to be conducted through a remote control system from tower base or the network management center. Furthermore, radio optimization methods for CDMA-1X and 1xEV-DO air interfaces have been developed. This paper identifies the match between these two complementing technologies. The extent of potential performance improvement resulting from the exploitation of flexible antenna down-tilt and azimuth orientation is measured. Performance gains including capacity increase as measured independently by a simulator are measured. The ability to optimize pilot powers and antenna pointing independently is assessed. The study finds that optimization of pilot powers in a CDMA-1X system does not increase the performance of the system significantly and substantial reduction in capacity can be associated with pilot power optimization. However the optimization of the antenna parameters is able to yield substantial capacity improvements. Similarly, in a 1xEV-DO system the data throughput rate can be significantly increased by optimizing the antenna parameters.
