| Abstract(in English) | We have proposed a distributed smart antenna system (D-SAS) for wireless LAN, which suppresses the interference among OBSSs and improves the system throughput in high-density wireless LAN scenarios. We have also developed the prototype of wireless LAN AP with D-SAS and demonstrated the system throughput of the proposed scheme with stadium experiment. In this paper, we show the experimental evaluation of the developed wireless LAN AP with D-SAS on a train 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. |
