For high-density wireless LAN environment, the interference among overlapped basic service sets (OBSSs) is a serious problem. To address this issue, we have proposed distributed smart antenna system (D-SAS) for wireless LAN, which suppresses the interference among OBSSs and improves the throughput. We have also developed the prototype of wireless LAN access point (AP) with D-SAS and demonstrated the system throughput with stadium environment. In this letter, we evaluate the performance of the developed wireless LAN AP with D-SAS on a train environment and describe that throughput with D-SAS is superior to that with the conventional centralized antennas. It was found that the developed D-SAS AP provides twice system throughput larger than the conventional AP with centralized antennas.
