Given the potential market for wireless LAN W A N ) technology, capacity within the available 2 and 5GHz frequency bands is likely to fall short of market demands. Multiple-sector antenna arrays are known to be able to provide capacity enhancement by means of interference reduction through spatial filtering. In this paper, the performance of an eightelement circular array acting as an Access Point (AP) in indoor wireless LAN environments is analysed. Spatial-temporal channel data used witlhin

Performance analysis of the array employing a switched-sector controller within Hiperlad2 standard is appraised in terms of carrier-to-interference (Cm ratios. Results show that an isolation of up to 15dl3 can be achieved between the two polarisations by means off using an antenna array at the AP. It is shown that 54% of the time, 2 users per timeslot can be supported by the system.
