Methods for Measuring and Optimizing Capacity in CDMA Networks Using Smart Antennas
Scot D. Gordon, Martin J. Feuerstein, Michael A. Zhao · Kluwer Academic Publishers eBooks · 2005
Smart antennas for CDMA networks have now entered commercial service in a number of IS-95 cellular markets, where they are used to increase capacity through traffic load balancing, managing handoff activity and reducing interference. With the introduction of CDMA smart antennas comes the complex question of how best to first measure and then to optimize capacity. This paper outlines an approach for estimating the forward link capacity of a CDMA cell site using readily available CDMA metrics obtained from switch statistics and drive test data. This capacity model is applied to a realworld smart antenna in a commercial deployment, where a 27% capacity improvement is projected over the existing conventional antenna system These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
