Sensitivity analysis of capacity enhancement with adaptive multibeam antennas for DCS1800

The authors present results for the likely capacity improvement when an adaptive multibeam antenna is used in conjunction with air interface parameters, as with the DCS1800 system. An analysis is made of the possible capacity enhancement while taking into account parameters such as power control, radio channel characteristics and different frequency reuse patterns. The results show that a substantial capacity improvement can be achieved with adaptive antennas, and also highlight the sensitivity of the capacity to operational parameters
