In Part 1 an experimental demonstration of both transmit and receive beamforming supporting SDMA user access was given. In Part 2 some implementation issues critical to the performance of an adaptive antenna system are studied from a practical point of view. Results for the sensitivity of the system to calibration errors and the linearity of the transmit power amplifiers are now presented from measurements made during the field trials
