Abstract	We present measurement results with a GSM1800 smart antenna base station. The base station is equipped with an adaptive antenna array processor that allows in every GSM frame full beam adaptation in uplink and downlink. The smart antenna processing is based on the estimation of the directions of arrival in uplink. It includes separate DOA trackers for uplink and downlink, angular diversity, and beamforming with broad nulls. Measurements in a static line{of{sight (LOS) scenario demonstrate the potential to suppress interference by 25dB. The smart antenna achieves a bit{error ratio (BER) of 1% at a carrier{to{interference ratio of 14dB. A eld measurement in a microcell setup con rms the tracking capability even in scenarios with strong multipath. In a non{LOS situation we achieve an average signal{to{noise gain of 7:4dB, while it increases up to 8:3dB in a LOS environment. The angular diversity concept results in an additional diversity gain of 5:8dB at the 1% BER level in case of NLOS when a dual beam con guration is applied.
