Increase in performance of a new or deployed system by cell site re-configuration

In a CDMA system deployed using the hexagonal cell arrangement, locations can exist where there are too many available pilots, while there are not sufficient in other locations. This can lead to degradation in performance at these locations. Preliminary results on a simple but effective change in the underlying cell architecture and deployment strategy that can alleviate some of these problems is presented. This is achieved by re-orienting the transmit antennas which helps balance the number of signals by distributing them more evenly and thus increasing overall performance. This reduces the effect of the pilot pollution and increases the worst case E/sub 0//I/sub 0/ while also reducing the interference on the forward and reverse links. This is especially beneficial for wireless local loop (WLL) systems or microcells where channel conditions exhibit line-of-sight properties.
