This paper shows the results for a direction of arrival (DOA) algorithm, which is designed for downlink beamsteering in a GSM related system. Measurement campaigns have been conducted for an 8 element adaptive antenna array in an urban environment. The results using measurement data indicate that an averaging window size of one SACCH frame (0.48s) is a wise choice for DOA estimation in a non-FH network or a FH network using DTX. Downlink beamsteering performance is analysed for different antenna array configurations and different number of fixed beam directions. The performance evaluations are made for both the measured data and data obtained from simulations
