We developed a high speed wireless LAN prototype in the 5GHz band. Maximum transmission rate
of the developed WLAN equipment was 324Mbit/sec using 6 multi-channels of 802.11a. We
proposed a novel frame aggregation scheme to improve MAC efficiency. The proposed frame
aggregation scheme had a feature of an adaptive aggregation size selection depending on the
wireless channel conditions and application requirements. Throughput performance was obtained
from simulation using a multiple station system with the proposed frame aggregation. A throughput
of more than 150Mbit/sec was achieved with an evaluated system of 10 STAs. We also found that
the measured throughput of more than 170Mbit/sec was achieved using the proposed frame
